| Abstract |
This paper presents how to find proper operating points of FACTS devices to enhance the steady-state security level considering line contingency analysis. There generic types of FACTS devices such as series controllers, shunt controllers, and series-shunt controllers are introduced and applied to maximize a security margin and to minimize security indices. Security indices related to line flows and bus voltages are utilized and minimized iteratively in this paper. Contingency analysis is performed to detect the most severe single line fault. In various load conditions, FACTS devices are tested to establish appropriate preventive or corrective action without generation re-dispatching or load shedding. The FACTS operation scheme is verified on the IEEE 57-bus system in a line-faulted contingency. |
