摘要
An improved maximum power point tracking (MPPT) algorithm is presented in this paper which can track the maximum power point effectively. The variable step size perturbation and observation (P&O) method is achieved based on the reference voltage of maximum power point, and the power curves of photovoltaic (PV) arrays model are analyzed in this paper. The simulation demonstrates that the algorithm can overcome the shortcomings of P&O method and constant voltage tracking (CVT) method obviously. The designed algorithm offers many advantages, including achieving simply, tracking fast, high accuracy and better adaptive capability. © 2013 ICIC International.
