An Improved Bat Algorithm for More Efficient and Faster Maximum Power Point Tracking for a Photovoltaic System Under Partial Shading Conditions

IEEE Access, 2020
Solar modules under partial shading (PS) conditions will result in power and voltage characteristic curves (P-VCC) having multiple peaks. If the maximum power point cannot be obtained, the output power of the solar modules will be greatly reduced. Hence,

Analysis of the operation of PV strings at the MPP closest to the nominal MPP voltage instead of the global MPP based on measured current–voltage curves

EPJ Photovoltaics, 2022
Under non-uniform operating conditions, photovoltaic (PV) generators may have several maximum power points (MPP) and voltage of the global MPP (GMPP) may vary quickly over a wide voltage range which may cause problems for tracking of the GMPP.
