Abstract:To address the issue of traditional algorithms being prone to local optima during the maximum power point tracking (MPPT) process due to the multipeak characteristic of photovoltaic array output power curves under partial shading conditions, this paper proposes an MPPT control strategy combining the improved Black-winged kite algorithm (TBKA) and the Perturb and observe method (P&O), referred to as TBKA-P&O. In the global search phase, the population is first initialized using the Tent-Logistic-Cosine chaotic mapping. Then, a tangent flight strategy is introduced to enhance the search efficiency and convergence accuracy of the TBKA. Additionally, a dynamic lens imaging reverse learning strategy based on a greedy approach is designed to improve search diversity and prevent local optima. In the local search phase, the P&O method is incorporated to achieve rapid localization and high-precision tracking of the maximum power point. To verify the effectiveness of the proposed algorithm, a photovoltaic power generation system simulation model was constructed, incorporating the traditional P&O algorithm, the BKA-P&O algorithm, the quantum CS-P&O algorithm, and the TBKA-P&O algorithm. Experimental results demonstrate that the TBKA-P&O algorithm achieved tracking accuracies of 100%, 99.97%, 99.96% and 99.96% under four operating conditions, with corresponding tracking times of 0.093, 0.090, 0.077 and 0.047 s. Compared to other algorithms, the TBKA-P&O algorithm exhibited significant advantages in terms of dynamic tracking speed, steady-state tracking accuracy, and power oscillation control.
