Abstract
Based on interaction with farmers, few post photovoltaic (PV) irrigation installation issues like diminishing water discharge due to increasing depth of ground water level, prolonged idleness (40%-60% time over a year) including morning/evening, no alternate use after irrigation, high maintenance cost of brushless dc pump, low return on investment (ROI), surrounding shading effect, etc., are identified. To address above issues, a co-operative movement for PV irrigation scheme-based solution is implemented by integration of PV arrays of two farmers (minimum) using multi-input dual-output controller with single-ended primary-inductance converter design. Control features like maximum power point tracking, energy transfer, optimum power utilization and sharing, vector control inverter, protections are adapted. MATLAB simulation and real-time field data result shows ROI per kilowatt improvement by 5.97%, reduced PV energy cost per watt by 14.89%, additional morning, evening PV extraction by 13.68%, and overall daily excess energy yield and water discharge by 18.75% and 24.74% for each farmer.
