摘要

Application of FACTS controller called static synchronous compensator STATCOM to improve the performance of power grid with hybrid wind-diesel system is investigated. The essential feature of the STATCOM is that it has the ability to absorb or inject fastly reactive power with power grid. Therefore, the voltage regulation of the power grid with STATCOM FACTS device is achieved. Moreover, restoring the stability of the power system having hybrid wind-diesel system after occurring severe disturbance, such as faults or suddenly step up wind speed is obtained with STATCOM controller. One of the most common controlling devices in the industry is the Proportional-Integral (PI) controller tuned by Genetic Algorithm (GA) is introduced. Genetic algorithm is employed to find the optimal values for PI controller parameters in a very short time. These methods are tested in MATLAB and their results are obtained. The dynamic model of the power system having hybrid wind-diesel system controlled by proposed STATCOM is developed. To validate the potential of the STATCOM FACTS controller, the studied power system is simulated and subjected to different severe disturbances. The results prove the effectiveness of the proposed STATCOM controller in terms of fast damping of the power system oscillations and restoring the power system stability.
