A Chaos Control Method of the Interconnected Power System Based on Fuzzy Delay Feedback
In order to improve the control effect of existing methods on power system oscillation chaos,a chaos control method for interconnected power system is designed based on fuzzy delay feedback.Firstly,the mathematical model of the interconnected power system is constructed,and then a fuzzy delay feedback chaotic controller is designed based on fuzzy delay feedback.The controller takes signal difference differential and signal delay difference as input to avoid finding feedback gain.The controller parameters are optimized by particle swarm optimization,and finally the chaos of the interconnected power system is controlled by the optimized controller.A hybrid transmission system is built as an experimental interconnected power system,and the application performance of the proposed method is tested through this system.The test results show that the chaos control performance of the design method is satisfactory,which proves that the proposed method is a control method with anti-interference performance.
