An efficient MPPT algorithm for PV modules under partial shading and sudden change in irradiance

This paper proposes a new method for maximum power point tracking (MPPT) under different environmental conditions, such as partial shading and sudden change in irradiance. The method consists of three parts - checking the partial shading occurrence, searching for global peak (GP) and reducing the oscillations around maximum power point (MPP). The simulations results show the proposed algorithm is able to track true global maxima. The tracking speed and efficiency are increased compared to the reference algorithm.
