Design and analysis of PV-DVR For Interconnected Wind System Using Fuzzy Logic Controller

Abstract

This paper examines the advantage of PV-DVR system on wind farm system fed to infinite bus system to compensate for various voltage variation with different faults conditions and to improve Total Harmonic Distortion during the mitigation of unbalance in the system. A wind farm management system is connected to grid is consider and analyzed issue related to voltage sag/swell. Later on, application of dynamic voltage restorer tried to improves system voltage profile by regulation various controllers with different fault conditions. Compensation depends on PI and Fuzzy logic Controller (Mamdani) are evaluated. With broad investigation under various faults and load sided conditions are performed utilizing the shortcoming of generator. Examination of simulation results of DVR works better with Fuzzy logic controller then PI control. Representation of DVR at different load conditions and the importance of injection transformer are likewise discussed when Grid connected to wind farm management system with different wind conditions. The reproducibility of these controllers is thoroughly verified using MATLAB/Simulink and results demonstrated.
