Photovoltaic Array Dynamic Reconfiguration Based on an Improved Pelican Optimization Algorithm

Electronics, 2023
After prolonged operation, external objects may obstruct the photovoltaic (PV) array, resulting in prolonged partial shading. The dynamic reconfiguration of PV arrays uses a switch matrix to change the electrical positions of the PV cells in the array, and it is an effective method to solve the problem of partial shading.
