Abstract :
A method and an algorithm based on this new method are presented. The effectiveness of the algorithm is illustrated by studying a 20-unit midwestern utility system, the EPRI 174-unit synthetic utility system D, and the EPRI 155-unit synthetic utility system E. The algorithm produces the same unit commitment schedule for the 20-unit system as a frequently used DP-STC algorithm in 15 s of computation time versus 524 s, respectively. The computation time is approximately linear with the number of hours in the unit commitment horizon. For the EPRI 174-unit system the algorithm requires only 205 s of computation time on a VAX 11/780 for a 48-hour horizon
