Effective Photovoltaic Integration and Power Quality Improvement on Parallel Feeders using Dynamic Multi Converter Controller

Abstract

Growing phase of industry and living standards in modern world brings drastic changes in modern utility structure and control. Gradually, green sources takes place of traditional sources and aids the current utility power delivery for consumer loads. Green source and more sensitive loads integration to grid demands effective controller and reliable grid structure. In this paper, an effective grid structure with dynamic multi converter controller is proposed to alleviate disturbances in current and voltage on parallel feeders simultaneously. Soft computing based controller effectively integrates the photovoltaic green source and utilizes the power generated to aid the controlling action and to provide the desired power required on lines. Dynamic multi converter controller takes care of current and voltage disturbance alleviation, green source power integration and harmonics suppression on parallel lines under distorted & balanced and distorted & unbalanced source conditions. Performance of proposed Dynamic Multi Converter Controller with traditional and soft computing techniques is studied and compared in MATLAB/SIMULINK platform.
