Real power flow control of 2 bus MC-UPFC using fuzzy logic controllers [articol]

Abstract

This paper deals with the design and testing of 2 Bus power system incorporated with Matrix Converter based Unified Power Flow Controller [MC-UPFC] to improve the transmission parameters such as real power and reactive power in both the generator side and the load side. The MC-UPFC is the rich topology in the Flexible AC Transmission System [FACTS] which is capable of controlling both the transmission parameters voltage injected and the angle of injection simultaneously with the switching technique of Direct power control by the smooth sliding control which gives less ripple in the injecting control parameters such as control voltage [VC] and voltage angle [α]. Hence the sliding surface and relevant control switching state of the MC can be controlled by the Fuzzy Logic Controller [FLC] which gives the robust and autonomous decision making in the selection of the appropriate switching state for the effective real power control in the power system. The work has been carried out in the MATLAB Simulink simulator which gives the finest controlling features and simple design procedures and easy monitoring of the output
