Tuning of PID controller of synchronous generators using genetic algorithm

摘要

Control of synchronous generators such as automatic voltage regulators have been developed to maintain stability and to improve damping of power systems. When an operating condition changes greatly, however, such controllers may become less effective because of nonlinearity of the power system. The mathematical model of AVR system has been established for control and analysis using a flexible and fast tuning method based on genetic algorithm (GA) technique. Tuning with different population size and generations number have been used to determine the optimal values of the PID controller parameters to improve the transient response of the system.
