A hybrid FFA-MPSO algorithm for solving economic power dispatch problem with valve-point effect

Abstract

This paper developed a new method to solve the economic power problems (EPD) considering the valve-point effects in power systems. The method is based on a hybrid algorithm composed of FFA algorithm and micro Particle Swarm Optimization (MPSO) .The searching process starts with the FFA by initializing a group of random fireflies, then the search is pursued by the MPSO, then the best results (better than FFA) found from MPSO are also communicated to the FFA as an initial space search.
The method suggested was applied to three cases different of power systems. The cost the property of convergence and the effectiveness of calculation of the method suggested were explored by the comparison with the recent existing techniques for problems of EPD to consider the valve-point effects.
