This paper presents a heuristic solution for short-term thermal unit commitment. The algorithm has been developed as a FORTRAN based production type program. Tests of this algorithm on data provided by a midwest utility have demonstrated satisfactory results. The proposed algorithm produces the same unit commitment schedule as a standard dynamic programming (DP) based algorithm in one fourth the computation time for the DP based algorithm for the provided data. The algorithm is nearly linear with the number of unit periods. A unit period is defined as the on-line duration time versus operation level for each unit. Present operating system restrictions limit the prototype to thirty thermal power units as implemented on a PS/2 Model 50 personal computer.
