Voltage profile of a power system is directly interacted with reactive power. One of the major causes of voltage instability and hence voltage collapse is due to imbalance management of reactive power. Flexible AC transmission System (FACTS) devices uplifts voltage stability limits and reduces line losses. Identification of an appropriate location to fix the FACTS device is a critical task. This paper deals with Constraint Factor Particle Swarm optimization (CFPSO) algorithm to find optimal location as well as size of FACTS device (Static Synchronous Compensator – STATCOM) to meet the objectives. The proposed approach was investigated on standard benchmark system IEEE 30-bus. From the outcomes, it is pragmatic that, there is an improvement in voltage stability margin and minimization in power loss by optimally locating STATCOM device in the power system.
