DEMOCRATIC PSO ALGORITHM FOR THE ECONOMIC DISPATCH PROBLEM WITH VALVE-POINT EFFECTS

Abstract

This paper presents an optimization algorithm called Democratic Particle Swarm Optimization (DPSO), aiming to solve the economic dispatch problem. The DPSO algorithm is applied in the original version and also in a new version in which it is endowed with the chaotic Sine map (DPSO-Sine algorithm). The performance of DPSO and DPSOSine algorithms is tested on two systems having 13, and respectively 40 generating units. The results show that DPSO and DPSO-Sine have better performances than PSO algorithm and few other optimization techniques used to solve the economic dispatch problem.
