Agricultural Photovoltaic Water Pumping System Performance During Partial Shading Condition

Photovoltaic (PV) water pumping assemblies powered by sensorless vector controlled induction motors are gaining popularity in various applications. Partial shading conditions (PSC) pose a challenge for classical maximum power point tracking (MPPT) algorithms like perturb and observe (P&O). This paper proposes integrating modified invasive weed optimization (MIWO) with P&O to dynamically optimize PV power output under PSCs, ensuring maximum power extraction even in rapidly changing weather conditions.
