PowerModelsACDCsecurityconstrained (PMACDCsc)

PMACDCsc is a Julia/JuMP package for steady-state security-constrained optimization problems for hybrid AC/DC grids. PMACDCsc extends PowerModelsSecurityConstrained.jl to the features of PowerModelsACDC.jl. The code is engineered to address the problem specifications such as:

• Security-constrained optimal power flow (SCOPF);
• Security-constrained unit commitment (SCUC);
• Post-preventive SCOPF curative re-dispatch;
• Contingency filtering (severity index (SI filter), and non-dominated contingency (NDC filter));
• Security-constrained transmisssion network expansion planning (SCTNEP);
• Optimal power and frequency control ancillary services (OPFCAS); and
• Marginal Loss Factor (MLF) calculation.

Building upon the PowerModels.jl and PowerModelsACDC.jl architecture, the code supports the formulations such as:

• ACPPowerModel; and
• DCPPowerModel.

Moreover, the code supports the following netowk data formats:

• Matpower ".m" files; and
• PTI ".raw" files (PSS(R)E v33 specification).

SCOPF implimentations

PMACDCsc provides several SCOPF formulations conforming to the ARPA-e GOC Challenge 1 specifications extended for hybrid AC/DC grids, which are given as follows.

Two-stage mathematical programming model (TSMP): complete base and contingency case models:

run_scopf_acdc_contingencies(data, scopf_formulation, filter_formulation, scopf_problem, scopf_solver, filter_solver, setting)

As an example, it can be used as:

result = PowerModelsACDCsecurityconstrained.run_scopf_acdc_contingencies(data, PowerModels.ACPPowerModel, PowerModels.ACPPowerModel, PowerModelsACDCsecurityconstrained.run_scopf, Ipopt.Optimizer, Ipopt.Optimizer, setting)

TSMP model: complete base and contingency case models with soft constraints and penalized slack variables:

run_scopf_acdc_contingencies(data, scopf_formulation, filter_formulation, run_scopf_soft, scopf_solver, filter_solver, setting)

TSMP model: complete base and contingency case models with soft constraints, penalized slack variables, and smooth approximated generator's frequency and voltage response, and AC/DC converter's P-Vdc droop control:

run_scopf_acdc_contingencies(data, scopf_formulation, filter_formulation, run_scopf_soft_smooth, scopf_solver, filter_solver, setting)

TSMP model: complete base and contingency case models with soft constraints, penalized slack variables, and mixed-integer based generator's frequency and voltage response, and AC/DC converter's P-Vdc droop control:

run_scopf_acdc_contingencies(data, scopf_formulation, filter_formulation, run_scopf_soft_minlp, minlp_scopf_solver, filter_solver, setting)

Decomposition based model conforming to the ARPA-e GOC Challenge 1 Benchmark heuristic developed in PowerModelsSecurityConstrained.jl, which is extended to include AC/DC converter station and DC grid models. The contingency case branch flow constraints are enforced by PTDF and DCDF cuts and penalized based on a conservative linear approximation of the formulation's specification.

run_scopf_acdc_cuts(data, scopf_formulation, filter_formulation, run_acdc_scopf_cuts, scopf_solver, filter_solver, setting)

The above mentioned decomposition based model with soft constraints and penalized slack variables:

run_scopf_acdc_cuts(data, scopf_formulation, filter_formulation, run_acdc_scopf_cuts_soft, scopf_solver, filter_solver, setting)

Proof-of-concept studies

Several scripts are provided to showcase how effectively PMACDCsc solves the real-world research problems:

• The scripts directory provides differnt test case examples of SCOPF implimentations.
• The src/nem directory provides the AC/DC SCOPF huiristic for the Australian National Electricity Market (NEM).
• The src/nem directory provides the AC/DC OPFCAS for the Australian NEM.
• The scripts directory provides the MLF calculation huiristic for the Australian NEM.

The Australian NEM datasets are available at Synthetic-NEM-2000bus-Data.
