【Abstract】 This paper briefly describes the basic particle swarm algorithm,and elaborates the mathematical model and variable constraints in the reactive power optimization.To solve two major problems facing the particle swarm algorithm: easy to fall into local optimal solution and relatively slow post-convergence rate,it proposes two methods which were simulated in IEEE-6 node system.The simulation results prove the feasibility and superiority of the algorithm.更多还原
