Abstract

In the power grid system, the ultimate goals are to transmit power with high power quality and power factor, economical and low risk of system failure. The ever increasing of power demands and loads especially non-linear loads making the power system network become complex to operate and the system becomes insecure with large power flows without adequate control. Renewable energy sources, which are expected to be a promising alternative energy source, can bring new challenges when connected to the power grid system. However, the generated power from renewable energy source is always fluctuating due to environmental conditions. In the same way, wind power source injection into an electric grid affects the power quality due to the fluctuation nature of the wind and the comparatively new types of its generators panel. One way to introduce power system control is by applying controller known as FACTS (Flexible AC Transmission System) controllers. STATCOM (Static Synchronous Compensator) and SSSC (Static Synchronous Series Compensator) is one of the FACTS controllers and can be introduced to the power system to regulate terminal voltage and to improve system’s stability and power quality. The FACTS devices (STATCOM and SSSC) control scheme for the grid connected with wind energy generation system is simulated using MATLAB/PSAT in power system block set. By using IEEE 14 bus power system network, the effectiveness of STATCOM and SSSC are tested by applying the controller at the critical location of the power system.
