Optimal Location of STATCOM for Voltage Security Enhancement Using PSO

 Abstract : Maintaining the power system security is a major task for the power system. Contingency analysis is used to know the effect at of the outages like failure of the equipment, transmission lines, etcs. Contingency analysis calculates the voltage violations. FACTS devices are used to reduce the voltage violations in the power system. STATCOM is the one of the shunt connected FACT s device which injects or observe the reactive power in the transmission lines.PSO algorithm is used for finding the optimal location of the STATCOM due to the cost of the FACTs devices. After placing the STATCOM perform the contingency analysis. The proposed methodology test on IEEE30 bus system.
