基于改进BBO算法的PSS参数优化的鲁棒性研究
Research on Robustness of PSS Parameter Optimization Using Improved Biogeography-based Optimization Algorithm
摘要
Abstract
Unreasonable configuration of PSS parameters may cause poor suppression effect of low frequency oscillation,or even damage stability of the power grid.Therefore,this paper firstly builds linear equations of the generator,the excitation system and PSS as well as related objective functions under multiple operating modes and multi-electromechanical oscillation modes so as to optimize corresponding PSS parameters.Secondly,it combines the difference algorithm (DE)and the bioge-ography-based optimization algorithm(BBO)for improving migration operators and variation parts.Finally,in PSASP it es-tablishes part of northwest Yunnan power grid by simulation and verifies effectiveness of the proposed optimized objective functions and improved BBO-DE algorithm. Simulation indicates the optimized PSS parameters have good adaptabilities which can effectively improve damping ratios of the system and adapt to multiple operating modes of Yunnan power grid.关键词
