Combined Economic and Emission Dispatch by using Hybrid PSO-GA with Real and Reactive Power Constraints

Abstract — This paper uses a hybrid PSO-GA for solving the combined economic and emission dispatch problems with real and reactive power constraints. The objective of Economic Load Dispatch is to minimize the overall cost of generation with required constraints. This paper concentrates on both the total production cost and total emission taken into account with satisfying constraints. Hybrid PSO-GA algorithm combines the advantage of PSO and GA. PSO algorithm can be used during the first stage of solving the optimization problem near the global optima. The last particle of the PSO is taken as the initial population of GA and it continues to further refine the optimized solution.
