Stability enhancement issues of power grid
This chapter gives an overview about the basic principle and operation of various shunt, series and series-shunt types of flexible alternating current transmission system (FACTS) controllers. The steady-state power transfer capability can be improved significantly in the power system with various FACTS controllers, and it is the main focus of this chapter. This can be achieved only by optimal placement of FACTS controllers in the network, otherwise they have negative impact on the system. To demonstrate the concept of power-transfer capability enhancement concept under steady-state operating condition, static VAr compensator (SVC) and thyristor-controlled series compensator (TCSC) have been considered. The simulation results were carried out for IEEE 30-bus and the New England 68-bus test systems to check the effectiveness of the algorithm.
