Diverse Emperor Penguin Algorithm for Partially Shaded PV Array Reconfiguration

Periodica Polytechnica Electrical Engineering and Computer Science
A significant challenge in the operation of Photo-Voltaic (PV) array is partial shading, which drastically reduces the power output. Shaded arrays exhibit numerous local Maximum Power Point (LMPP) alongside a single Global Maximum Power (GMP). Reconfiguring shaded modules to extract the GMP is crucial, and achieving this relies heavily on a uniform ...
