This repository contains an open source Perl 5 system to construct Microsoft Excel spreadsheet models to calculate electricity distribution use of system charges.
The repository also contains data used by regional electricity distribution companies in England, Scotland and Wales in models to set their use of system charges, in a format suitable for use with the Perl 5 code.
Go to http://dcmf.co.uk/models/ to download some workbooks built using this code.
To get started with building spreadsheet models on your own computer using this code, follow the instructions below.
You need a terminal or console interface, and Perl 5 (v5.8.8 or later).
This is normally easy to set-up on desktop and server computing platforms:
- On Apple macOS, the built-in Terminal.app and Perl 5 installations are good.
- On Microsoft Windows, the built-in Command Prompt and the Strawberry Perl package available from strawberryperl.com are good.
- On FreeBSD and many Linux distributions, console applications and Perl 5 are either pre-installed or available from the ports/packages system.
On mobile operating systems, setting up a suitable environment is much more troublesome; the dcmf.co.uk/models website might better meet your needs.
To test whether you have a suitable version of Perl 5, try this at the Terminal or command line:
perl --version
Either download https://github.com/f20/power-models/archive/master.zip and extract all the files from it, or use a git client to clone this repository.
Change directory to the root of the repository and try these sample commands:
perl -Icpan -Ilib -MSpreadsheetModel::Book::Manufacturing -e "SpreadsheetModel::Book::Manufacturing->factory->runAllWithFiles('models/Samplers/FormatSampler.yml')"
perl -Icpan -Ilib -MSpreadsheetModel::Book::Manufacturing -e "SpreadsheetModel::Book::Manufacturing->factory(validate=>['lib'])->runAllWithFiles('models/CDCM/2017-02-Baseline/%-extras227.yml','models/CDCM/2017-02/SPEN-SPM.yml')"
If this fails, examine the error messages. Sometimes the problem is a missing module which can be installed from CPAN (www.cpan.org).
The "EDCM Stata validator" and "EDCM Stata generator" folders under models contains Stata tools to test aspects of implementations of the EDCM charging methodology. See "How to use.txt" under "EDCM Stata validator" for more information. This code is deprecated and unmaintained.
