| Abstract: | A novel PID controller is designed for the excitation system of synchronous generator and its parameters are optimized using a modified Genetic Algorithm(GA)to overcome the subjectivity and raise the search speed.The computing results show that the modified GA is more quickly and precisely than Error-and-Trial method and conventional GA,and the simulation results indicate that the modified-GA-based PID controller can improve dynamic characteristic of power system compared with conventional excitation contro... |
