PowerModels Experiment Results

This section presents results of running PowerModel.jl on collections of established power network test cases from NESTA. This provides validation of the PowerModel.jl as well as a results baseline for these test cases. All models were solved using IPOPT.

Experiment Design

This experiment consists of running the following PowerModels commands,

result_ac  = run_opf(case,   ACPPowerModel, with_optimizer(Ipopt.Optimizer, tol=1e-6))
result_soc = run_opf(case, SOCWRPowerModel, with_optimizer(Ipopt.Optimizer, tol=1e-6))
result_qc  = run_opf(case,  QCRMPowerModel, with_optimizer(Ipopt.Optimizer, tol=1e-6))

for each case in the NESTA archive. If the value of result["termination_status"] is LOCALLY_SOLVED then the values of result["objective"] and result["solve_time"] are reported, otherwise an err. or -- is displayed. A value of n.d. indicates that no data was available. The optimality gap is defined as,

soc_gap = 100*(result_ac["objective"] - result_soc["objective"])/result_ac["objective"]

It is important to note that the result["solve_time"] value in this experiment does not include Julia's JIT time, about 2-5 seconds. The results were computed using the HSL ma27 solver in IPOPT. The default linear solver provided with Ipopt.jl will increase the runtime by 2-6x.
