摘要

提出了一种基于STATCOM的减振方法来增强电力系统小信号稳定性。本文采用基于STATCOM的超前滞后辅助控制来抑制电力系统的振荡。采用简化的灰狼优化算法对控制动作变量进行优化。对输入机械功率和参考电压进行阶跃摄动，并考虑基于ITAE的目标函数进行优化。在扰动条件下，与粒子群算法和GWO算法相比，所提动作能显著提高系统的动态稳定性。

Enhancement of dynamic stability of power system by optimal STATCOM control action

A STATCOM based damping action has been proposed for small signal stability enhancement of power system. An auxiliary lead-lag control action based on STATCOM has been employed here to damp power system oscillation. The control action variables are optimized by a simplified Grey Wolf Optimizer algorithm. Step perturbation of input mechanical power and reference voltages are executed and ITAE based objective function considered for optimization problem. Pertained to disturbances the dynamic stability has been found to be much improved by proposed action, in contrast with PSO and GWO algorithm.
