An Improved Hybrid Particle Swarm Optimization Method for Distribution Network Planning

An improved hybrid particle swarm optimization for distribution network planning problem was proposed. The special mutation operator and the crossover operator among extremums of dynamic neighborhood were led. Another method called' trying its best to meet the radial restriction' was proposed to solve the contradiction between coping with discrete variables and judgment of radial network. Numerical simulation results demonstrate that the method possesses excellent global convergence capability, and is feasible and efficient. It is valuable to popularize the application of the PSO in power system.
