Comparison of state-of-the-art transmission constrained unit commitment formulations

The paper reviews and compares several mixed-integer linear programming formulations of the transmission constrained unit commitment problem. It analyzes these formulations and provides extensions that properly address all the generator initial conditions. Computing times to solve the unit commitment problem using these different formulations are analyzed and compared. Tests were performed using a version of the IEEE RTS-96 system that has been updated to include generator types that better reflect contemporary generation mixes. Detailed data on all the power system parameters are provided, including initial generator conditions.
