Improved Power System Stabilizer Considering Imperialist Competitive Algorithm Based on Levy Mutation
摘要
Abstract
To strengthen the capability of suppressing low-frequency oscillations when designing the traditional power system stabilizer(PSS)and improve its setting range and control capability,a PSS system is designed based on a frac-tional-order proportional-integral-derivative(PID)controller that has advantages of flexible control capability and satis-fying tracking performance. Meanwhile,the imperialist competitive algorithm(ICA)based on Levy mutation is adopted to optimize the configuration of the improved PSS system,and simulations are carried out on the design model under a single-machine infinite bus system. Simulation results show that the proposed design can fully suppress the low-frequen-cy oscillations of power system and flexibly control the controlled object with satisfying control effect and robustness.关键词
