A Novel Fuzzy-Logic UV Controlled Utility-Grid Integrated Solar-PV Based Water-Pumping System

The ample availability of fuels, reliable operation, low-cost and less maintenance are the key parameters for utility-grid integrated solar-PV based water-pumping system for irrigation sectors. The utility-grid integrated solar-photovoltaic based water-pumping system enables the customer to operate the pumping system continuously regardless of climate-conditions. And also, furnish energy to utility-grid during water-pumping is in off-state. A Fuzzy logic-unit-vector control scheme is used to regulate the voltage-source converter for controlling the bi-directional power-flow between the solar-PV and utility-grid system. In this work, incremental-conductance maximum-power point tracking of solar-PV and the enhanced power-quality features are attained in utility-grid system. The operation and performance of proposed unit-vector fuzzy-logic controlled utility-grid integrated solar-PV based water-pumping system is verified using Matlab-Simulink tool, results are presented.
