Instances
UnitCommitment.jl provides a collection of large-scale benchmark instances collected from the literature in a standard data format and, in some cases, extended with realistic unit commitment data, produced by data-driven methods. If you use these instances in your research, we request that you cite UnitCommitment.jl, as well as the original sources (as listed below).
Raw instances files are available at our GitHub repository. Benchmark instances can also be loaded with
UnitCommitment.read_benchmark(name), as explained in the usage section, where name is one of the names below.

2. MATPOWER
MATPOWER is an open-source package for solving power flow problems in MATLAB and Octave. It contains a number of power flow test cases, which have been widely used in the power systems literature.
Because most MATPOWER test cases were originally designed for power flow studies, they lack a number of important unit commitment parameters, such as time-varying loads, production cost curves, ramp limits, reserves and initial conditions. The test cases included in UnitCommitment.jl are extended versions of the original MATPOWER test cases, modified as following:
-
Production cost curves were generated using a data-driven approach, based on publicly available data. More specifically, machine learning models were trained to predict typical production cost curves, for each day of the year, based on a generator's maximum and minimum power output.
-
Load profiles were generated using a similar data-driven approach.
-
Ramp-up, ramp-down, startup and shutdown rates were set to fixed proportion of the generator's maximum output.
-
Minimum reserves were set to a fixed proportion of the total demand.
-
Contingencies were set to include all N-1 transmission line contingencies that do not generate islands or isolated buses. More specifically, there is one contingency for each transmission line, as long as that transmission line is not a bridge in the network graph.
For each MATPOWER test case, UC.jl provides two variations (2017-02-01 and 2017-08-01) corresponding respectively to a winter and to a summer test case.
2.1 MATPOWER/UW-PSTCA
