OPTIMAL LOCATION OF TCSC AND SVC DEVICES TO ENHANCE POWER SYSTEM SECURITY
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 1
Abstract
Contingency analysis in power system security is an important tasks in emerging energy management systems. Contingency ranking using the performance index value is a method for the line outages in a system, which ranks the first highest performance index line and proceeds in a descending manner based on the calculated PI values for all the line outages. Contingencies results in voltage limit violations and overloading of lines. FACTS devices are used to enhance the security of power system by minimizing or eliminating the number of lines overloaded and violating the bus voltage limit. It is necessary to optimally locate these devices in the power system because of the high capital investment cost. In this paper, single contingency analysis for the considered test system has been performed, based on which the contingency ranking is done. Based on contingency ranking, locations of TCSC and SVC are chosen, and the effects of these FACTS devices after contingency condition have been studied. The effect of the proposed controller has been tested on Modified IEEE 30 bus system using MATPOWER 5.1.
