Voltage Stability Improvement Using Facts Devices

Abstract

Current electric system are inclined to failure because of numerous reasons. With the expansion in power demand, the operation and planning of power system is be- coming more and more complex. So, the problem of instabilities is observed in the entire system working environment and it required to modify the future planning and reconsider the method of operation. Recently, some of network blackouts occurs due to voltage collapse. The problem of voltage stability play a major role in deregulated power system. FACTS devices are used because of maintain the active and reactive power control as well as adaptive to voltage control simultaneously because of their

exibility and fast control characteristics. Placing of FACTS devices in a suitable lo- cation is important to improves the voltage stability and reduce power system losses. The project shall focus on the determination of type of FACTS device, placement and explore the rating for the same.
