State Estimation of Power System with Interline Power Flow Controller

, and . International Journal on Electrical and Power Engineering, 1 (2): 5 (July 2010)

Abstract

Now-a-days Flexible A.C. Transmission System (FACTS) controllers are incorporated into the power system network to control the power flow and enhance system stability. Traditional state estimation methods without integrating FACTS devices will not be suitable for power systems embedded with FACTS controller. Based on the conventional power system state estimation model, a new method is proposed wherein an IPFC based power injection model is incorporated in the state estimation algorithm. Interline power flow controller (IPFC) is one of the versatile FACTS device. The proposed method is tested on Anderson and Fouad 9-bus test system and the results are presented.
