Design and control of STATCOM fed Distributed Generation using Fuzzy Controller based Reverse voltage Technique

Abstract

Power quality enhancement is one of the major concerns from the last few years due to fluctuations occurring in the power transmission and distribution. This paper presents the design of distributed generation system for reducing power quality problems in the distribution system and grid side supply. It involves the design of distributed generation using renewable energy source and also reverse voltage technique based multilevel inverter for integration into the grid. This paper also presents the design of fuzzy controller based modified synchronous rotating frame theory for regulating the DC link voltage and multilevel inverter currents. The system was simulated using MATLAB Simulink and the results are verified with single phase and three phase non linear loads.
