Abstract

Photovoltaic (PV) water pumping (PVWP) system is a promising application, specifically in developing countries with many regions not connected to the public grid. However, implementation of such PVWP systems is still limited due to low return on investment (ROI). During morning and evening hours, the available PV power is not sufficient to operate the water pumping system and thus hinders the utilization of the installed PVWP system at full potential. To address the above limitations, in this work introduces a cooperative irrigation-based PVWP (CI-PVWP) system with multi-input multi-output DC-DC converter-based inverter is proposed. The proposed CIPVWP has multiple functionalities like increased PV utilization during morning/evening hours, additional utilization of PV energy as battery energy storage, and maximum power point tracking under both uniform and partial shading/mismatching conditions. Numerical results depicts the satisfactory performance of the CI-PVWP system under various considered operational scenarios.
