Reactive Power Optimization Based on Improved Particle Swarm Optimization Algorithm Considering Voltage Quality

摘要

With the target of voltage quality, an improved PSO algorithm is proposed in reactive power optimization(RPO) of power system. The algorithm adopts some way of chaos theory and flexible inertia weight based on basic PSO and suitable penalty factor on function constraint, which can overcome limitations of partial constringency in basic PSO and improve the efficiency in global optimizing. The simulation of IEEE-14-buse shows this algorithm has better convergence than basic PSO algorithm.
