摘要

As the reliance on photovoltaic (PV) systems grows across various applications, optimizing their performance especially under mismatching conditions becomes essential. The behavior of a PV system is heavily influenced by its environmental conditions. To enhance overall system performance, it is critical to optimize each individual system component. This paper introduces a reconfigurable PV module, derived from the standard module through an easy-to-implement modification, aimed at improving the module performance under mismatching conditions. Additionally, a converter with variable switching frequency control is proposed to reduce its frequency dependent losses and thus optimize its efficiency. The reconfigurable PV module comprises submodules that can be arranged in series or parallel via a switching matrix depending on the operating conditions. To assess the feasibility and reliability of the proposed system, its performance was benchmarked against that of a conventional system, which features a standard PV module and a converter operated by a global peak power tracking algorithm. Additionally, the performance of the proposed system was also compared to that of a system utilizing distributed power electronics based on differential power processing converters. The results showed that the proposed reconfigurable module generates between 3.43% and 29.87% more power compared to the standard module. In addition to that, the converter efficiency is precisely improved from an average of 86.55% to 94.29% with the implementation of variable switching frequency converter control.
