Abstract

In this paper, enhanced genetic algorithm (EGA) is used to solve the short-term unit commitment problem (UCP) and the enhanced lambda iteration (ELI) method is used to solve the economic dispatch (ED) sub-problem. Based on EGA, the problem specific operators have been integrated in the simple GA algorithm and thus, enhanced the quality of the solution. Performance of EGA is tested on 2 test systems comprising of 4-unit and 10-unit over the scheduling time horizon of 8 hours and 24 hours respectively. Results demonstrate that the proposed method is superior to the other reported methods in the literature.
