基于环形拓扑的粒子群优化算法在无功优化中的应用

电力系统无功优化是一个复杂非线性的动态问题,将粒子群优化算法用于电力系统优化虽然取得了广泛的应用,但粒子群本身存在早熟的问题使得无功优化过程中容易陷入局部最优,导致优化效果不理想。针对粒子群因为全连接拓扑造成的早熟问题,将一种环形拓扑的粒子群算法用于无功优化,使用标准测试函数测试表明其性能较一般粒子群好,然后将其用于IEEE14节点的无功优化,结果表明其收敛结果明显优于原粒子群。

Application of Particle Swarm Optimization Algorithm Based on Ring Topology in Reactive Power Optimization

Reactive power optimization for power system is a complicated nonlinear dynamic problem. It is widely applying particle swarm algorithm in power system optimization, but precocity of particle swarm is a reason for causing local optimum in process of reactive power optimization which may result in unsatisfactory optimization effectiveness. Aiming at precocity caused for reason of full join topology, this paper applies a kind of ring topology particle swarm algorithm in reactive optimi- zation and uses standard testing function to prove better performance of this new algorithm than other general particle swarm. Practical application of this ring topology particle swarm algorithm in IEEE14 node indicates obvious superior con- vergence result than original particle swarm.
