Enhancement of Transmission System Loadability During Contingency by Optimal Allocation of FACTS Devices Using Particle Swarm Optimization

摘要

This paper deals with the enhancement of transmission system loadability with single contingency by optimal location and settings of multi-type Fexible AC Transmission System (FACTS) devices such as Thyristor-Controlled Series Compensator (TCSC) and Static Var Compensator (SVC). Contingency Severity Index (CSI) is used for the optimal location of FACTS devices. To enhance the socioeconomical benefits, the solution to the problem is optimized using Particle Swarm Optimization (PSO) technique thereby minimizing the Installation Cost (IC) of FACTS devices and Severity of OverLoading (SOL).
