Congestion mitigation on high voltage power lines using multiple TCSC & UPFC

Abstract

With severe overload on transmission lines, further exchange of power flow is affected due to congestion on power transmission lines. This paper investigates the effect of Flexible AC Transmission System (FACTS) devices like TCSC and UPFC in congestion mitigation. The proposal uses multiple FACTS devices of similar type and investigates their effect on congestion mitigation in high voltage transmission lines. This proposal is tested on IEEE-14 bus system.
