Economic Dispatch Using Particle SwarmOptimization

[摘要] The important optimization problems regarding issue is to determine and provide an economic condition for generation units based on the generation and transmission constraints ,which is called Economic Dispatch (ED).In the present paper ,Particle Swarm Optimization (PSO)is used to find fast and efficient solutions for different power systems with different 3 and 6 generation units numbers. The proposed algorithm is capable of solving ED problem which determines in such a way the algorithm minimizes total cost function .The results reveal that the proposed algorithm is capable of reaching a higher quality solution including mathematical simplicity, fast convergence robustness to cope with the non-linear ties of economic load dispatch problem.
