基于IFA的PSS与STATCOM阻尼控制器参数协调优化策略
Coordinated Optimization Strategy for the Parameters of Damping Controller Applied to PSS and STATCOM Based on Improved Firefly Algorithm
摘要
Abstract
In order to optimize the damping characteristics of power system,an improved firefly algorithm(IFA)is used for the coordinated optimization of parameters of the damping controller applied to power system stabilizer(PSS) and static synchronous compensator(STATCOM)in this paper. Based on the introduction of the Gaussian decreasing in?ertia weight to the standard firefly algorithm(FA),the global and local searching abilities of FA is coordinated,so its optimization performance can be increased. In addition,the eigenvalues and characteristics of electromechanical oscil?lation modes of the power system under a variety of operation conditions are used as an objective function to ensure the adaptability and robustness of this coordinated optimization strategy. The proposed method is applied to a four-generator two-area system. Simulation results show that under a variety of operation conditions,the damping ratios of the system after coordinated optimization have been improved significantly,which can effectively suppress the low frequency oscil?lation of the power system and improve its dynamic stability performance.关键词
