摘要:

电力系统无功优化可以降低系统的有功损耗,保证系统运行的安全性和经济性.采用向量粒子群优化(PPSO)算法求解电力系统无功优化问题,在算法中通过初始化得到向量的相位角,并将相位角引入速度更新过程,这样可以更有效地提高搜索精度.在IEEE-14节点系统中,采用PPSO算法、标准粒子群优化算法、随机惯性权重粒子群优化算法和改进吸引排斥粒子群优化算法进行无功优化仿真实验对比,结果表明,PPSO算法可以更好地降低有功损耗.

Abstract:

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
