Abstract

This paper uses genetic algorithms (GAs) to solve the economic load dispatch (ELD) problem for the Eastern region of Thailand´s utility (EGAT) power system. A piecewise model of cost characteristics is derived for the combined cycle and the cogeneration power plants in the system and utilized for the ELD formulation. Results of ELD are obtained by using a conventional GA and micro GA models. Both the models effectively solve the ELD problem and reduce the operating cost. However, the micro GA model offers faster convergence
