Enhanced Grey Wolf Optimizer Based MPPT Algorithm of PV System Under Partial Shaded Condition

Abstract: ABSTRACT:Partial shading condition is one of the adverse phenomena which effects the power output of photovoltaic (PV) systems due to inaccurate tracking of global maximum power point. Conventional Maximum Power Point Tracking (MPPT) techniques like Perturb and Observe, Incremental Conductance and Hill Climbing can track the maximum power point effectively under uniform shaded condition, but fails under partial shaded condition. An attractive solution under partial shaded condition is application of meta-heuri… Show more

“…Finally, the proposed MPP search will finish when only a few of the best individuals converge in a specified range. As a result, the convergence time of SDRA is less than other methods, such as improved PSO [15], [25] ACO [12], enhanced GWO [17], bat algorithm (BA) [19], and hybrid method [26].…”

“…Although the improved PSO can track time-variant global MPP, it still has undesirable steady-state oscillations around this global MPP. The GWA method and the shuffled frog leap algorithm (SFLA) method can efficiently find the global MPP with greater accuracy and less computation time than other methods, as stated in [17] and [18]. The BA [19] and CS [20] have been issued with better demonstrations by numerical simulation and experimental results.…”

“…They have a very strong dominant leadership and hierarchical such as military system [57], which can be classified into four levels (leadership pyramids); leaders wolves called alpha (α), subleaders called beta ( ), delta (δ) and the lowest wolves called omega (ω) wolves as shown in Fig. 7 [33,57], where the dominance of wolves increases from top to bottom [58]. The behaviour of these Grey Wolves is inspired in the optimisation field such as PV energy system.…”
