Voltage Stability Enhancement in a Wind Generator Connected Electrical Network Using FACTS Devices

چکیده
This paper presents voltage stability in an electrical network when connected by wind generators. Due to several advantages wind energy is the growing renewable energy. Nowadays, wind energy is penetrating into the conventional power network. Due to random variations in wind speed, the output power and terminal voltage fluctuates continuously. The influence of wind generators on the power quality is becoming an important issue; non-uniform power production causes variations in system voltage and frequency, therefore, a wind farm requires high reactive power compensation. The advances in high power semiconductor devices have led to the development of Flexible AC Transmission System(FACTS).This paper presents the impact of wind energy integration on voltage stability and the goal of FACTS devices to control the reactive power injection. Power flows, nodal voltage magnitudes and angles of the power network are obtained by iterative solutions using MIPOWER , thereby regulating the bus voltages. Keywords— Power flow, Newton-Raphson method, Wind generator, FACTS devices, Voltage regulation
