Performance Analysis for Control of A Unified Power Flow Controller (UPFC) Using MATLAB Simulink

Abstract

The long transmission system is required to transfer generated power to distribution system. Hence, maximum power transfer devices with flexible operation are essential in transmission system. Thus, it is necessary to add Flexible AC Transmission System (FACTS) devices at the proper locations. Unified Power Flow Controller (UPFC) is the best FACTS transmission system device for ensuring adequate power flow between generating and distribution via transmission lines. The UPFC consists of two converters which likely to work as STATCOM and SSSC to make a proper power flow. In this paper modeling and analysis of UPFC is presented under platform of MATLAB/Simulink. Extensive responses are incorporated in results section with proper analysis under various operating conditions.
