PV and QV analysis for finding the optimum location of FACTS device to investigate the effectiveness in KR power system using PSS/E

Abstract

This paper presents the effect of Static Synchronous Compensator (STATCOM) device in power system for power flow and voltage stability analysis. The stability of power system is most important evaluation that is needed to be considered under various contingency states. This paper presented Power-Voltage (PV) and Reactive power-Voltage (QV) analysis which have been widely used in steady state of power system in normal operating condition and gives important details about the loading of the system and voltage stability. The shunt and series compensation can be used to increase the voltage and flow in the power system. Kurdistan Region Power System (KRPS) used to verify the effectiveness and performance of STATCOM in power system. PSS/E proposed as power system software for KRPS. The result shows that the proposed Full Newton Raphson (FNR) method spends less execution time and the optimum placement for STATCOM for enhancing static voltage stability margin and improves the power transmission capability of the line is the 'weakest bus' of the system.
