Design and Analysis of Hybrid Optimization Technique for Maximum Power Tracking in PV under Uniform and Partial Shading Condition

Abstract

Since the power–voltage characteristic curve of photovoltaic (PV) arrays has multiple peaks under partially shaded conditions, the conventional maximum power point tracking (MPPT) control methods will fail to work. However, the particle swarm optimization (PSO) algorithm is very suitable to solve the multi-extreme optimization problem. Hence, this paper proposes a new algorithm search method PSO and FFA to track the maximum output power of photovoltaic arrays. Finally, the performance of the proposed model is verified by simulations. From the results, it is revealed that the proposed topology exhibits higher tracking power than the conventional one.
