Abstract
This study focuses on a power transfer strategy that efficiently feeds a field-oriented controlled (FOC) permanent magnet synchronous motor (PMSM) drive into a water pumping system (WPS) from a solar photovoltaic (PV) array and a single-phase grid. The need for a consistent water supply cannot be met by a standalone system due to the intermittent nature of photovoltaic (PV) systems. A grid intergraded WPS is suggested here to lessen this. The consumer can operate their water pump continuously regardless of the amount of solar insolation thanks to grid integration. Additionally, when water pumping is not necessary, the PV power can be sent into the utility grid. The shared DC link between the solar PV system and utility grid is controlled by switching pulses produced by the VSC using the unit vector template theory. To power the PMSM connected to the water pump, a sensor-less FOC is used. Under fluctuating insolation, the best power can be extracted from solar PV arrays using an intermediate stage boost converter. For maximum power point (MPP) operation, the duty ratio is generated using a perturb and observe approach. The suggested system is validated using a lab-developed prototype after being simulated in the MATLABSimulink environment with the SIM Power system toolkit. The system prototype is put to the test under a variety of solar insolation conditions as well as grid anomalies including voltage sag and voltage swell.
