Interactive Power Flow (IPF) is a family of programs for doing power flow studies. IPF models the balanced steady-state operation of an electric power network. It is used by power system planners, design engineers, and students to investigate electric power networks, determine bus voltage distribution, study real and reactive power flows in lines, check for line overloads, understand system reactive requirements, plan area controls, examine effects of load shedding, generator dropping, and line outages.
IPF was originally developed by Bonneville Power Administration (BPA). IPF was made public domain by Bonneville Power Administration (BPA) back in 1994. This project is a fork of Bonneville Power Administration's Interactive Power Flow (IPF) programs including the Transient Stability Program (TSP). The original source code for this repo was obtained from ftp://ftp.bpa.gov, which no longer seems to be available. The goal of this project is to breathe life into this codebase again and continue enhancing it while preserving all of its legacy features. Most of the command line tools are working. Note that the original programs had a GUI component built with Motif X Window, but given how dated it is, most will find it cumbersome to use relative to modern applications.
You can find complete documentation for this project here. The documentation at that site has details on how to install it, what command line tools are available, record and command syntax for defining the model and studies, how to use the C API, how to use the GUI, and more. Most of the content on that site came from the original documentation for IPF and TSP applications in these manuals so if something is missing from the ReadTheDocs site, check the manuals. Additionally, check out John Schaad's website for some additional history on the original BPA project.
There are a variety of sample cases in the data directory of this repo. Some of them came from original IPF codebase others came from publically available cases like Texas A&M's set of synthetic cases found here. None of the data is from real power system networks since such information is generally considered confidential by Transmission System Operators.
If you're looking for a quick reference on using some of the IPF commands, see below.
Batch Power Flow (bpf) executes using commands from a Power Flow Control (.pfc) file. Users write commands in the .pfc to do power flow runs. The documentation describes the commands available. You can try it out using test cases found in the data directory. To run a case just run bpf <controlfile.pfc> or bpf and follow the prompts. For example,
$ bpf bench.pfc
The output is a Power Flow Output file <casename>.pfo. When you use bpf, you must first create a <casename>.pfc file with the appropriate commands to accomplish the solution task at hand. At runtime these commands are accepted by bpf and executed according to a logical processing order determined by the program. Hence you need not be concerned with the ordering of commands in your PFC file. Input commands will be processed first, and a solution done automatically before any output is produced. Finally, a new base (.bse) file will be created, if you have requested one. See the IPF Batch Users Guide for more information.
Cuts out a section of the entire system model and prepares it to be set up for running with its own slack bus.
Usage: ipfcut <controlfile.pfc> or ipfcut
Output: Powerflow Network Data file <cutcasename.bse>
This is a stand-alone program that cuts out a subsystem from a solved base case (.bse) file. Flows at the cut branches are converted into equivalent generation or load on specially formatted +A continuation bus records. An ensuing power flow run should solve with internal branch flows and bus voltages which are identical to those quantities in the original base case.
In almost all cases, you will have to convert one of the buses in the cut subsystem into a slack bus, to replace the original system slack bus.
Several methods are available to define the cut system: bus names, zones, base kVs, and individual branches. A pi-back feature replaces selected buses with a passive-node sequence (lines consisting of sections) with the original loads pi-backed in proportion to the line admittances.
Below is a sample control file:
( CUTTING, PROJECT=EWEB, CASEID=EWEBCUT1 )
>DEBUG<
.>EXCLUDE_BUSES<
.>INCLUDE_BUSES<
.>PI_BACK_BUSES<

/ DEBUG, TX = ON, DC_MODEL = ON
(STOP)
The batch version of ipfsrv. It accepts a Power Flow Control Language (PCL) file. This is an alternate set of commands from PFC used by bpf.
Usage: ipfbat <controlfile.pcl>
Example of use: ipfbat test.pcl.
The PCL commands used with ipfsrv and ipfbat (standard filename extension of .pcl) are described in the IPF Advanced Users Guide and in Appendix A of the IPF CFLOW Users Guide. Many of the PFC commands from Chapter 4 of this manual are supported, but not all, and there are many additional new commands.
ipfbat allows you fine control over the case and solution engine (ipfsrv). When you use the PCL approach, you first create a PCL file with the
appropriate commands to accomplish the solution task at hand. At runtime these commands are interpreted by ipfbat. The PCL file commands are processed sequentially. Additional PCL command files may be specified by name, so that a chain of PCL files may be processed in one run. See the IPF Advanced Users Guide for details.

Usage: gui
Screen/Mouse-driven, Point-and-Click control of IPF powerflow program.
The X-based (X Window System using the Motif Window Manager) push-button and
menu-driven Graphical User Interface (gui) program that works in conjunction
with the power flow server, ipfsrv. Documentation is in the IPF Basic/GUI
Users Guide.
When you use the GUI, you use the dialog boxes, menus, windows, etc. This makes data input, output, and manipulation easy. In addition to allowing basic case solution tasks to be accomplished, certain specialized tasks such as creating coordinate files, taking line outages graphically, printing plots, tapping lines, viewing summary reports, and line impedance calculations, are available.
For information about how to work with the GUI dialog
boxes, menus, windows, etc., see the IPF Basic/GUI Users Guide. This guide
also has a tutorial to show you how to solve straightforward power system
cases. However,for some more involved analysis tasks, you need to use the bpf,
ipfbat, and CFLOW approaches.
Usage: ipfplot <coordinatefile.cor> <basefile1.bse> <basefile2.bse(opt)>
Output: PostScript Plot file <plot.ps>
Batch plotting program to produce printed map files in PostScript (.ps)
format. The program accepts a coordinate file (.cor) and a base case file
(.bse) on the command line, as well as an optional second base case file. When
the second base case file is specified, a difference plot is produced. You can
also use ipfplot to produce bubble diagrams.
The same coordinate files (.cor) are used by both gui and ipfplot, but not
all capabilities are available in the gui. Documentation is in the IPF
Advanced Users Guide.
Creates customized output reports and summaries.
Usage: ipf_reports <basefile1.bse> or ipf_reports
CFLOW is a C library (libcflow) for IPF. This repo contains several programs that have been created with CFLOW:
- pvcurve
- post_pvcurve
- qvcurve
- findout
- lineflow
- mimic
To create a CFLOW program or routine, you write your routine using the C
programming language (at least the main must be in C), including the header
file cflowlib.h, which defines all the structures and unions which allow
access to the powerflow input and solution values. To retrieve these values,
you call various CFLOW routines. You can also pass modifications to ipfsrv,
ask for a new solution, etc. See the IPF CFLOW Users Guide for information
on writing these programs.
See section 3.4 of the IPF Advanced Users Guide for information on including these routines in .PCL control files, along with other processes.
Powerflow (ipfbat) output report post-processor. Generates a table of the
loading of overloaded branches for a list of outages with data from one or
more .pfo files. Uses CFLOW library.
Original author: William D. Rogers, BPA
Generate a table of values showing the loading of various branches under the condition of a specified outage for various cases. For each case, the "Summary of bus and line problems for each outage" report in the corresponding .pfo file is scanned for the loading, percent of rating, and rating type for each branch-outage pair. One input file contains a list of .pfo file path names. A second input file contains a list of outages and branch-outage pairs. Where branch-outage pair is specified, data is collected from each .pfo file for that pair. Where only an outage is specified, all of the overloaded branches for that outage are reported. Data fields in the output report table are character delimited to ease importing to MS Excel or DECwrite.
Powerflow (`ipfbat`) output report (`.pfo`) files.
Text file containing a list of *.pfo file path names, 'pfo file list'.
Text file containing overloaded and outaged branchs, 'outages list'.
Prompts user for file names and ouput options. Defaults in brackets [].
> Enter 'pfo file list' file spec [pfolist.dat]:
> Enter 'outages list' file spec [outages.dat]:
> Enter 'output report' file spec [fastout.rpt]:
> Enter 'output report' page width....... [132]:
Text file containing a table of reported values, 'output report'. stdout messages.
INPUT FILE FORMATS:
*.pfo files - Output reports generated by Powerflow (`bpf`) that contain the
"Summary of bus and line problems for each outage" report.
'pfo file list' - a text file containing a list of powerflow (`bpf`) output
files (*.pfo) with one file specification per line. The symbols !,*, or
. in the first column indicate a comment line. The default filename is
pfolist.dat.
For example:
! Any of the three symbols {!*.} in column 1 indicate a commment line.
. Names of powerflow output files listed one per line.
'outages list' - a text file containing a list of either monitored-branch
and outaged-branch pairs or outaged branches. If only a single branch
name is listed on a line, it is taken as the name of an outage and all
branches overloaded by that outage will be reported in the output file.
If a pair of branches is listed on a single line, the first is taken to
be an overload caused by the outage of the second listed branch. The
loading of that overloaded branch will be listed in the output file, but
the other overloaded branches for that outage will not be reported
unless specified explicitly.
Branch names are listed in Powerflow netdata format. An optional
vertical bar '|' can separate the overloaded from outaged branches when
listed together on a single line. Spaces before and after the vertical
bar are ignored. Branch id starts with the first character in the type
field. Branch types L, E, T, and TP are allowed. The symbols !, *, or
. in the first column indicate a comment line. The default file name is
outages.dat.
For example:
. Any of the five symbols {!*.} in column 1 indicate a commment line
. This same file may be used by LINEFLOW in which case the Outaged Branch data
. is ignored.
. Monitored Branches | Outaged Branches

L BEAVER 115 TILLAMOK 11500
TP BROAD ST 115 EASTPINE 115
OUTPUT REPORT OPTIONS:
'output report' name - any valid file specification. The default is
fastout.rpt.
Page width - the width in columns of the 'output report'. Data for three
cases of delimited data fields fit in 132 columns and 1 in 96 which the
program defaults to if fewer columns are specified. A large page width
can be specified to cause all of the cases be printed in one table. If
more cases are included than will fit across the page, additional tables
are generated, following consecutively. The default is 132 columns.
OUTPUT REPORT FORMAT: Data delimiter - an vertical bar '|' character is inserted between each data field in the 'output report'. The vertical bar is used as a delimiter so that the tables can be imported into Microsoft Excel of DECwrite.
A table of values is generated. For each overloaded-branch/outaged-branch pair, the critical rating is given and for each case, each branch's load and percent of rating is given. Critical ratings are based on the first case that is read, which is assumed to be the base case. Flags are placed in the output report in the |F| columns to indicate the type of rating found in the .pfo file.
The table is then printed to a text file. For example (fictionalized data):
Data fields delimited with |. Note: A full report of even one case requires 100 columns. Shown here wrapped around. Actual output is 132 columns wide.

Powerflow (ipfbat) output report post-processor. Generates a table of outages
and corresponding branch overloads or bus voltage violations from multiple .pfo
files. Sorts and screens. Uses CFLOW library.
DEVELOPER: William D. Rogers, BPA, TEOS (detail), 230-3806, wdrogers@bpa.gov
Works with the .pfo output files of /OUTAGE_SIMULATION runs as a
post-processor to screen and sort the results and present them in
tabular form. Tables of 'Outages and Overloads' or 'Outages and
Bus Violations' can be produced. Entries in these tables can be
screened according to Zone, Owner, Base kV, Loading and Bus Voltage.
Tables can be sorted by Zone, Owner, Base kV, or alphabetically. The
idea is to allow the user to automate the creation of a report
detailing the results of outages--saving time and reducing errors
from the current method of doing so which generally includes cut and
paste operation with an editor.
Data fields in the output report table are character delimited to ease importing to MS Excel or DECwrite.

*.log - Log/error file containing error messages, if any.
Stdout messages.
INPUT AND TRACE DATA FORMATS:
Forward-slash / tags alert the program to the type of data to follow. Data
should follow on subsequent lines, but not on the line with the / card.
/ tags and data are recorded in a trace (.TRC) file after all prompts have
been answered. The trace file is a record of input and can be user-modified
and input into the program on subsequent runs.
All characters after a \ (back slash) are ignored.
A line with a . in column one is ignored.
/INCLUDE
when this tag occurs in a trace file, a list of text file names will be
read from the following lines. Each file will be opened and scanned for
other / cards containing basecase, branch, or script data. The data
files (usually .DAT or .LIS) can also be specified at the /PFO or
/INCLUDE prompts when running interactively.
/PFO
a list of Powerflow analysis files (*.PFO). Multiple files may occur on
each line. To include a text file containing a list of pfo files,
specify it after a /INCLUDE card. The needed .PFO files are generated
by using IPF's fast outage capability through the /OUTAGE_SIMULATION
command.
The following "Summaries" are searched for in the *.PFO files.
Summary of bus and line problems for each outage
Summary of System Separations and Divergences
Summary of Common Mode Outages
note: at the "/PFO or /INCLUDE" prompt, *.pfo and include (data) files
may both be specified in a list form. For example:
/PFO or /INCLUDE
> Enter list of .PFO files (and/or data files): J.PFO, A.PFO, DIFF.TRC
where, J.PFO and A.PFO could be winter and summer cases and DIFF.TRC
could be a trace file requesting a list of branches loaded above 85%
and with overloads differing by 5% or more, belonging to BPA, in
zone NB, at 230kV, and formatted for export to Excel and sorted by
percent over-loading.
/OUTAGE, /COMMON_MODE, /OVERLOAD, /BUS
Branch and bus data is specified in Powerflow card format. Specify one
branch or bus per line. Only the key id items are required: T, L or
B for type, bus name(s) and kv(s). If section or circuit id are blank,
they are treated as wild cards and all branches between the specified
buses will be found. Note, this works much faster than using ?? for the
circuit and section.
Note: all branches will be sorted low alpha to high alpha and high kv to
to low kv in order to conform to the fastoutage data in the PFO file.
For wildcard searches, place at least one question mark, ?, in the data
and all non-blank characters will be matched. For example:
> Tycown< BUS1 ><V1> < BUS2 ><V2>cs (Lowercase fields optional)
> ? B??MON?????
will match any branch (transformer or line) whose owner starts with 'B'
and has a bus starting with 'MON'. Note: This function can be very
slow and base kv, if specified, must be in the form: [500.] instead of
[ 500] in its 4 digit field. Leave ckt and section blank if wild card
search is desired.
/OUTG_OWNER, /OUTG_ZONE, /OUTG_BASE_KV - outage and common_mode outages
/PROB_OWNER, /PROB_ZONE, /PROB_BASE_KV - overloaded branches, u/o voltages
Enter a list of owner, zones, or base kv after each appropriate tag.
The wildcard * may be used in owner or zone names. For example,
N* as a zone matches NA, NB, NC,...,NZ.
The bang ! symbol is used to exclude zones or owners. For example,
!NA, !NB will retrieve data on all zones except NA and NB.
To specify ALL ZONES or ALL OWNERS (these are the defaults) use ** and
***, respectively.
Base kv is specified explicitly or by range. For example,
69, 115, >230, <69, 115-500, are all valid. >115 gets all base kv
strictly greater than 115 kV, not including 115. 115-230 gets all
base kV between 115 and 230 kV including 115 and 230 kV. Use >0 to
specify ALL BASE KV; this is the default.
/LIMIT
This tag has up to seven valid data items:
MAX_DELTA_PCT = 5 (any valid percentage)
MAX_LOAD_PCT = 80 (any valid percentage)
MAX_500_PU = 1.100 (for 500 kV busses)
MIN_500_PU = 1.000
MAX_BUS_PU = 1.052 (for busses with kV less than 500 kV)
MIN_BUS_PU = 0.950
INC_SOLN_PROB = YES
note: for a difference report, both the MAX_DELTA_PCT and MAX_LOAD_PCT
must be satisfied or the MAX_DELTA_PCT and voltage limits, depending
on the type of report requested.
/REPORT
This tag contains all other program control data.
NAME = LINEFLOWX.RPT (specifies the name of the report)
TYPE = OUTAGE-OVERLOAD (or, OVERLOAD-OUTAGE, OUTAGE-BUS_V,
BUS_V-OUTAGE)
SORT = SOLUTION (or, ALPHA, BASE_KV, ZONE, OWNER, INPUT)
FORMAT = DATA_FULL (or, DATA_BRIEF, PAGE_WIDE, PAGE_COMPACT)
REMOVE_REDUNDANT = NO (or, YES; used with common-mode outages)
TRACE = ON (or, OFF, stops generation of trace)
DELTA = ON (or, OFF; differences between PFO files)
CASES_PER_TABLE = 6 (width depends upon FORMAT and TYPE)
A note on the REMOVE_REDUNDANT option:
A value of 'NO' causes FINDOUT to report all outages not filtered
out by other means, such as owner, zone, etc. This is the default.
A value of 'YES' causes FINDOUT to not report problems caused by
outages that have previously been taken as part of a common-mode
outage. This is an additional screening tool. For example, if
a bus delete common-mode outage resulted in a branch outage, that
branch would be taken out a second time by itself by the IPF
Fastoutage facility. This option allow the user to automatically
screen out the problems caused by the second occurance of that
branch outage.
OUTPUT REPORT FORMAT:
Data delimiter - a vertical bar '|' character is inserted between each data
field in the output report. The vertical bar is used as a delimiter so
that the tables can be imported into Microsoft Excel of DECwrite.
A table of values is generated. For each branch, the critical-rating is
given and for each case, each branch's load and percent of rating is given.
Critical ratings are based on the first case that is read. Flags are placed
in the output report in the |F| columns to indicate the rating type of
subsequent cases.
The table is then printed to a text file. For example (FORMAT = PAGE_COMPACT):
--------------------------------------------------------------------------------
. | |OUTAGES CAUSING OVERLOADS| | | | | | | A.PFO|||
. | | Outage followed by... | | | | | | |[ ]|||

For Generation Integration Studies, the use of Powerflow Plots showing proposed new generation facilities and associated system improvements is essential. Generally the diagrams available are the Standard BPA Powerflow Plots (.cor files) developed for the Budget Cases. Creation of new plots or modification of these existing .COR files is necessary to show the additional facilities. Manual modification using a text editor is very time consuming and is not intuitive. Use of the IPF GUI is a very effective way to update the poweflow plots with the new system information, or to create new plots from scratch.
The following step-by-step procedure is a guide to the steps necessary to create (1) an updated .COR plot file based on an existing Budget Case Powerflow Plot .COR file, or (2) to create a new .COR plot file from scratch using the IPF GUI.
Procedure
- Modify Existing Budget Case .COR File:
Run the IPF GUI and click the appropriate "select" and "apply", and "load selections" buttons to load the base case file (.bse) already containing the added Generation and associated system improvements and the Budget Case coordinate file (.cor) for the part of the system you are going to show. Then click the "load selections" buttons to load them both. Then "File, Save-As" to save the .COR file with a name of your choice in your user directory. After that, activate the "Explode" function by clicking the 2nd Button in the 2nd Column, and click on the busses with the new generation and facilities you have added to the system model in the .BSE file. Then, activate the "Symbol Move" function by clicking the 5th Button in the 2nd Column, and use the mouse to rearrange the symbols on the diagram representing the new generation and facilities. When you are done, use "File, Save-As" to save your new .cor file.
- Click "Select" for Base Case File directory list
- Click the .BSE file you want to use
- Click "Apply"
- Click "Select" for Coordinate File directory list
- Click the .cor file you want to use
- Click "Apply"
- Click "Load Selections"
- After the .BSE and .COR files are loaded, click "View, Solution Data On"
- Click "File, Save-As". For "Coordinate", click "Select" and enter your new name for this coordinate file. Click "OK" , then click "Save" to save the .COR file; then click "Close".
Procedure
- Create New .COR File from scratch:
Run the IPF GUI and click the appropriate "select" and "apply", and "load selections" buttons to load the base case file (.bse) already containing the added Generation and associated system improvements and the Blank Template coordinate file (L85X11.COR or P85X11.COR) to show the part of the system you are going to show. Then click the "load selections" buttons to load them both. Then "File, Save-As" to save the .cor file with a name of your choice in your user directory.
Activate the "Bus Input Data" function by clicking the 6th Button in the 1st Column. The
cursor will change from an arrow to an open square. Close the "Bus Input Data" window.
Click "Edit, Alpha List" to bring up a list of all the busses in the .bse case. Now select the
bus you will use to start the diagram. Click in the "Search Bus Name kV" window and with
"CapsLock" on, type in the 1st letter of the bus name, then the 2nd, etc. until the bus name
appears in the list. Select the desired bus and click "Close". Then, with the mouse, locate the
1st bus at the appropriate location on the blank diagram, and click to place it there.
After that, activate the "Explode" function by clicking the 2nd Button in the 2nd Column, and click on the busses with the new generation and facilities you have added to the system model in the .BSE file. Then, activate the "Symbol Move" function by clicking the 5th Button in the 2nd Column, and use the mouse to rearrange the symbols on the diagram representing the new generation and facilities. When you are done, use "File, Save-As" to save your new .COR file.
- Click "Select" for Base Case File directory list
- Click the .BSE file you want to use
- Click "Apply"
- Click "Select" for Coordinate File directory list
- Click the .COR file you want to use
- Click "Apply"
- Click "Load Selections"
- After the .BSE and .COR files are loaded, click "View, Solution Data On"
- Click "File, Save-As".
- For "Coordinate", click "Select" and enter your new name for this coordinate file.
- Click "OK", then click "Save" to save the .COR file; then click "Close".

MODES OF OPERATION: MIMIC uses built in intelligence to prompt the user based on the information already provided. This serves to reduce the number of queries the user must answer to run the program.
MIMIC automates these operations:
1) Applying multiple changes to multiple base cases
2) Solving and screening multiple base cases
3) Comparing two or more base cases
4) Generating plots (including difference plots)
5) Building Excel-ready report tables
6) Logging all user input into a "TRACE" file
7) Performing multiple similar studies
8) Re-running studies with updated base cases
9) Automating /Outage_simulation studies
10) Solving basecases with /SOLUTION options
MIMIC screens data using these filters:
1) Line and transformer loading
a. maximum allowable loading
b. changes in loading
c. changes in loading above a threshold
2) Bus voltage
a. separate limits for 500 kV buses and sub-500 kV buses
b. maximum and minimum voltage
c. heavy winter conditions
d. changes in voltage
e. changes in voltage above a threshold
3) Owner (include, exclude, all, and/or wildcard; NA, !PR, A*, !T*)
4) Zone (include, exclude, all, and/or wildcard; NA, !PR, A*, !T*)
5) Base kV (list and/or ranges; 230, >350, <35, 69-115)
MIMIC reports these quantities:
1) Branch loadings
2) Bus voltages
3) Transformer tap settings
4) Difference in value between two base cases
5) /OUTAGE_SIMULATION reports go to their own file
MIMIC generates these reports:
1) Summary of Voltage Violations
2) Summary of Voltage Violations and Voltage Changes
3) Summary of Overloaded Transformers
4) Summary of Overloaded Transformers and Loading Changes
5) Summary of Overloaded Lines
6) Summary of Overloaded Lines and Loading Changes
7) Summary of Tap Positions
8) Summary of Tap Positions and Tap Changes

Report File - text file containing table of reported values.
Trace File - text file containing list of all input values.
Stdout messages.
Text file containing output from Powerflow (ipfsrv) called ipfsrv_cf.out.
MIMIC.LOG
*.pfo files generated with /OUTAGE_SIMULATION analysis.
INPUT FILE FORMATS:
trace file - this file contains a 'trace' of all inputs to MIMIC on a
previous run. It can be edited and modified. Information deleted from
a trace file will be prompted for on the next run. Thus, a trace file
can be set up to contain a list of 'default' inputs. To control the way
cases solve, add (all solution options can be used):
/SOLUTION
> solution option
> solution option
> etc. until done.
'base case/list' -
basecase - a single basecase name. MIMIC searches the local directory
and then the various basecase directories to find it.
basecase list - a text file containing a list of Powerflow cases with
one file specification per line. The file name should end in .DAT.
For example:
BASE.DAT
! The symbol '!' in column 1 indicates a comment line and is ignored.
! List the names of the powerflow cases one per line.
!
'pri chngs/list' -
pri chngs - Primary Changes file. Contains change records to be applied
to the base case(s).
pri chngs list - Primary Changes List file. A text file containing a
list of change files.
'aux chngs/list' -
aux chngs - Auxillary Changes file. Contains change records to be
applied to the base case(s).
aux chngs list - Auxillary Changes List file. A text file containing a
list of change files.
A change file example:
/CHANGES,FILE= *\
. REMOVAL OF THE COL FALL 230/115-kV TRANSFORMER FROM BASE
. SIMULATED LOSS OF 230/115-KV INTERCONNECTION
T D COL FALL 230 COL FALL 115
(END)
A list of primary changes example:
! The symbol '!' in column 1 indicates a comment line and is ignored.
! List the names of the change files one per line.
!
'ref base /list' -
ref base - a Reference Basecase name. MIMIC searches the local directory
and then the various basecase directories to find it.
ref base list - a text file containing a list of Powerflow cases with
one file specification per line. The file name should end in .DAT.
'cor file /list' -
cor file - a Coordinate File used for generating plots. MIMIC searches
the local directory and then the various basecase directories.
cor file list - a text file containing a list of Coordinate files with
one file specification per line. The file name should end in .DAT.
Outage simulation control file (OUTG_CON_FILE) - a text file containing
commands for /OUTAGE_SIMULATION studies. MIMIC will send a command
structured as follows:
/OUTAGE_SIMULATION, FILE = <OUTG_CON_FILE>, OUTFILE = <basecase>.PFO

Converts binary base file (.BSE) to an ASCII network data base file (.NET, .BPA, .PTI, or .GE).
This is the batch version of the "save netdata file" function built into the GUI/IPFSRV. This program generates a WSCC-formatted network data file in any of the following dialects: BPA, WSCC, or PTI. "Dialects" means that the file is still WSCC, but the data is generated with special processing or restrictions and is destined for use with other programs. In the case of the PTI dialect, that data is preprocessed by the PTI-proprietary conversion program WSCFOR. Documentation is in Appendix F of the IPF Batch Users Guide.

A new version of 'puf' (Path Use Factors aka Line Flow Analysis) corrects a factorization error and introduces new command-line options.
Usage: puf [-x|] [-lossless] [-pv] [-ai] [-g] [-ps] [-p1] [-c <cutfile>]
The parameters are:
-x<flag> : defines an Excel field separation character.
<flag> is usually set to "|" (vertical bar).
-pv : sets all buses as PV. Default is PV and PQ.
-ai : sets area interchange control on. Default is off.
-g : restricts sensitivities to generator buses only. Default is all buses.
-ps : includes phase-shifter sensitivities. Default excludes phase shifter
sensitivities.
-lossless : formulates the lossless sensitivities and should be used in
conjunction with -pv option. The lossless formulation minimizes the affect
of slack bus location. Default uses full Jacobian solution.
-l1 : sensitivities expressed as dLine/dP (default)
-l2 : sensitivities expressed as 1.0 + dLine/dP.
-c <cutfile> : constrain the flow path with the cut system defined by cutting
commands in <cutfile>.
Example, using a single parameter: puf -x|
You will be prompted for three files:
- basecase file name (.bse)
- output file name (.out)
- flowgate file name (.txt)
The flowgate file name consists of WSCC-formatted branches which define a
particular cut plane. For this example, use a single but critical branch, L RAVER 500 PAUL 5001 put in a text file, flowgate.txt
Generates voltage reactance curves. Automates production of P-V curve plot files and plot routine setup files for multiple base cases and outages.
