A novel Distributed FACTS controller based on combined two half-bridge inverter

Abstract

Flexible AC Transmission Systems (FACTS) devices are used to control flow of power in the transmission line to relieve congestion and limit loop flows. Due to, high cost and reliability concerns the widespread deployment of FACTS solutions have been limited. The concept of Distributed FACTS (D-FACTS) devices, as an alternative approach to realizing cost-effective power flow control, has been proposed by different researchers. This paper discusses design of a novel Distributed FACTS controller based on two half-bridge inverter combined as an alternative approach to realize cost-effective power flow control. The cost of D-FACTS controller base on combined two half-bridge is lower than recently D-FACTS controllers mentioned in literature. Simulation using PSCAD/EMTDC has been performed for conventional controllers and the proposed controller and the result are compared with respect to each other.
