Abstract

The advancement in power systems has led to the development of economic load dispatch (ELD) that is difficult to solve by classical optimization method. The proposed paper work is to evolve a simple and effective method for an optimum generation dispatch to minimize the fuel cost and emission cost of power networks. The approach is based on Particle Swarm Optimization (PSO) technique, its variants and Hybrid Differential Evolution HDE. The proposed techniques are tested on a 6-generator, 30-bus standard test system. The effectiveness of the proposed optimization is verified in simulation studies using MATLAB software. The PSO based approach has been extended to evaluate the trade-off curve between the fuel cost of power production and the emission cost according to the multi- objective function.
