This paper proposes an application of Evolutionary Programming (EP) to Reactive Power Planning (RPP) problem using Static VAR Compensator (SVC), Thyristor Controlled Series Capacitor (TCSC) and Unified Power Flow Controller (UPFC) considering voltage stability. Optimal location for FACTS controller is identified by using the Fast Voltage Stability Index (FVSI). The bus with minimum reactive load is considered as the most critical bus and the line with FVSI close to 1 is considered as the most critical line. Simulation results show the proposed method reduces the system losses and improves the voltage stability for the RPP problem.
