Reactive power optimization of power system can reduce active power loss and ensure the safety and economy of operation. Phasor particle swarm optimization (PPSO) is used to solve the problem of reactive optimizationin power system. The phase angle obtained through initialization is introduced into the speed updating process to improve the searching accuracy. In IEEE-14 node system, reactive optimization simulation experiments are conducted through PPSO algorithm, standard particle swarm optimization algorithm, stochastic inertia weighted particle swarm optimization algorithm, improved attractive repulsive particle swarm optimization algorithm. The simulation results show that PPSO can better reduce the active power loss.

Key words: phasor particle swarm optimization, power system, reactive power optimization, active power loss
