摘要

Due to the various peaks that are produced, partial shadowing (PS) is one of the key environmental elements that affect the maximum power (MP) output of photovoltaic (PV) systems. The current research describes a unique reconfiguration repeated application of a derived fundamental integer method based on the recursive addition approach protecting PV systems and abstract maximum power under partial shading conditions. This novel approach attempts to maintain a consistent row current by physically shifting the panels while maintaining the electrical connections. It enhances power by making sure the least number of shaded panels are put in the same row. A \({\mathbf{9}} \times {\mathbf{9}}\) PV array with short narrow, short wide, and long wide shading patterns is used in this study to test the effectiveness of the suggested approach using software models. The efficacy of the suggested method is also compared to other static reconfiguration approaches that have been proposed in the past, and it is found to be more effective for all the shading patterns taken into consideration in the current work. The increase in output power is as high as 34% in some cases.
