Abstract

This research paper presents a battery less PV–diesel hybrid water-pumping system is proposed for an agricultural site in Kufri, Pakistan. System sizing was carried out in HOMER, yielding a design comprising a 9.34 kW PV array, a 12-kW diesel generator, and a 13-kW power converter. The optimized configuration was subsequently modeled in Simulink to investigate electrical dynamics and source-transfer behavior. A current-based supervisory strategy was implemented to supply the motor from the PV inverter whenever the PV array current meets the pump requirement, and to transfer the load to the generator when PV current becomes insufficient. The simulated PV output, motor response, and transfer transients align with the operational trends predicted by HOMER. The findings confirm that the proposed battery less PV–diesel arrangement can reliably meet irrigation demand while reducing fuel usage and operating cost relative to a diesel-only system, making it a practical solution for rural areas with high solar potential and the need for firm backup supply.
