Performance Evaluation of IPFC with SMES on the Power System Stability

Abstract

Voltage Source Converter (VSC)-based Flexible Alternative Current Transmission Systems (FACTS) controllers are capable of providing reactive power support and control active and reactive power flow, which will result in improving the power transfer capability of congested transmission lines. The Interline Power Flow Controller (IPFC) and the Superconducting Magnetic Energy Storage (SMES) are the FACTS devices. This paper proposes the use of the IPFC in combination with the SMES as an effective device to enhance the stability of the Single Machine Infinite Bus (SMIB) power system taken as test system. SMES is connected to the dc side of IPFC through an interface with DC-DC chopper. The performance of the IPFC can be improved with the addition of energy storage. A detailed model of IPFC-SMES controller is proposed and a new control scheme is designed. The dynamic performance of the proposed device is validated through digital simulation carried out by using SimPowerSystems of Matlab/Simulink. The results of the simulation show that the used approach can significantly enhance the power system stability.
