Dynamic Reconfiguration Method for Improving PV Water Pumping System Efficiency in Partially Shaded Environments

While operating in a partial shadow scenario, photovoltaic (PV) plants display an imbalance in the array’s irradiance and produce less output power. Reconfigurable photovoltaic arrays or Dynamic Photovoltaic Arrays (DPV), which allow for the change of the inter-connections of PV modules in order to balance the irradiance distribution, have been offered in the past as a solution to this problem. The effectiveness of a solar photovoltaic water pumping system (SPV) is greatly diminished when partial shadowing (PS) conditions are present. The photovoltaic (PV) array’s output power is decreased as a result of the partial shadowing, which in turn results in a reduced amount of pumping output. As a result, the purpose of this study is to construct an intelligent SPV for a total cross tied (TCT) PV array. Illumination, polarity, and constant current are included into the design of intelligent SPVs. The real-time radiation data of each component in the TCT connection is measured by the irradiance sensor in the TCT connection. This research provides a dynamic re configuration procedure with the use of switches that boosts the PV array output power in comparison to a standard TCT connection under partial shadowing situations. The algorithm is based on real-time irradiation data, and it was developed in this paper. The increased water outflow of the SPV is a direct result of the increased output power. Maximum power point tracking, often known as MPPT, is an operation that makes use of both the voltage and current sensors. In addition, simulations and experiments have been carried out in order to validate the efficacy of the proposed system in a variety of PS situations. The findings that were achieved are quite encouraging due to the fact that the reconfiguration method increases the SPV’s efficiency.
