Multi-objective Power and Emission Dispatch using Modified Group Search Optimization Method

This paper presents heuristic modified group search optimization (MGSO) algorithm for solving combined economic power and emission dispatch (CEED) multi-objectiveproblem. Some modifications have been done on the proposed method to improve its convergence. Simulations have been doneon IEEE 30 bus standard system in order to validate effectiveness of the proposed method. Simulation analyzes mentioned system for pure power, pure emission and combined economic power and emission dispatch considering system loss. Numerical results indicate that, the proposed method has better performance andconvergence time, in comparison with some recently published papers.
