A Control Technique for Unification of DG Units to the electrical network Using Fuzzy Logic Controller

Yeluri Naresh, Dr.G.Sambasiva Rao

This paper proposes with a control method for unification of distributed generation resources using fuzzy logic controller to the utility grid.The theme is to reduce total harmonic distortion  reduction using fuzzy logic controller in utility grid while delivering to non linear loads. The proposed method provides compensation for active power  reactive power and harmonic load current during connection of distributed generation resources to the utility grid. The method of proposed system is first viewed in stationary reference frame then transformed in to  the synchronous orthogonal reference frame. The transformed variables are used to control the voltage source converter as heart of interfacing between DG resources and utility grid.matlab simulink model of the system is done using fuzzy logic controller.Simulation results based on total harmonic distortion reduction evenly presented
