基于PSO的配电网静止同步补偿器PI控制器整定

针对配电网静止同步补偿器(D-STATCOM)控制器参数难以整定且过分依赖经验,提出用粒子群优化(PSO)算法同时整定D-STATCOM电压控制器和电流控制器的方法,其寻优时间短,编程简单。通过不同系统参数、不同给定输入、不同负载情况下的多组优化实验,验证PSO优化算法寻优的有效性。最后通过仿真和实时控制实验验证了基于PSO算法的PI控制器具有良好的鲁棒性和动态性能。所进行的多组优化实验也为PSO编码选择提供一定参考。

Particle swarm optimization based on PI controllers' tuning for distribution static synchronous compensator

The parameters’ adjustment of distribution static synchronous compensator(D-STATCOM) is difficult and relied on experience.A particle swarm optimization(PSO) method was applied to adjust the parameters of both voltage controller and currents controllers for DSTATCOM in this paper.The adjustment process is quick and easy.The PSO optimization ability was verified and compared by experiments under different system parameters,setup values,and load conditions separately.The effectiveness of PSO based PI controllers were demonstrated by simulation and real-time experiments.The optimization ability experimant provide an option for the selection of the coding parameters of PSO method.
