Particle Swarm Optimization Technique with Time Varying Acceleration Coefficients for Load Dispatch Problem

Economic load dispatch is a non linear optimization problem which is of great importance in power systems . While analytical methods suffer from slow conversion and curse of dimensionality particle swarm optimization can be an efficient alternative to solve large scale non linear optimization problem.A lot of advancements have been done to modify this algorithm. This paper presents an overview of Classical PSO and then PSO with TVAC. Results are compared first with GA then CPSO and PSO with TVAC. Keywords— Classical particle swarm optimization (CPSO), Particle swarm optimization with time varying coefficients(PSOTVAC),Swarm intelligence, non smooth cost functions. __________________________________________________*****_________________________________________________
