REAL POWER FLOW CONTROL OF 2 BUS MC-UPFC USING FUZZY LOGIC CONTROLLERS

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
