EFFECT OF GENETIC PID POWER SYSTEM STABILIZER FOR A SYNCHRONOUS MACHINE

This paper focuses on the use of advanced techniques in genetic algorithm for solving power system stabilization control problems. Dynamic stability analysis of power system is investigated considering Proportional-Integral-Derivative power system stabilizer for modern power systems. Gain settings of PID- PSS are optimized by minimizing an objective function using genetic algorithm (GA). The operation of a Genetic PID with PSS controller is analyzed in simulink environment. The development of a Genetic PID with power system stabilizer in order to maintain stability and enhance the performance of a power system is described widely. The application of the Genetic PID with PSS controller is investigated by means of simulation studies on a single machine infinite bus system. Controller design will be tested on the power system to prove its effectiveness. Analysis reveals that the proposed PSS gives better dynamic performances as compared to that all of mentioned methods. The superior performance of this stabilizer in comparison to PSS and without PSS proves the efficiency of this new Genetic PID Controller with PSS controller. The comparison studies carried out for various results such as speed deviation, field voltage, rotor angle and load angle in Simulink based MATLAB environment.
