CMPVI-based MIDO scheme under SSE for optimum energy balance and reduced ROI

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.
