研究目的
To develop an algorithm for optimizing the electrical configuration of a PV array during non-uniform aging processes to maximize power generation without replacing aged PV modules.
研究成果
The proposed PV array reconfiguration algorithm effectively maximizes power generation from non-uniformly aged PV arrays by reducing mismatch losses. The algorithm is applicable to PV arrays of various sizes and improves power output significantly without the need to replace aged modules.
研究不足
The study does not consider voltage limitation in the reconfiguration process. The algorithm's effectiveness is demonstrated through simulation, and real-world implementation may face additional challenges.
1：Experimental Design and Method Selection:
The study involves developing an algorithm for PV array reconfiguration based on the aging status of PV modules. The algorithm sorts PV modules iteratively in a hierarchy pattern to reduce mismatch effects.
2：Sample Selection and Data Sources:
The study uses PV arrays of different sizes (4 × 4, 10 × 10, and 100 × 10) with non-uniform aging factors randomly generated for simulation.
3：List of Experimental Equipment and Materials:
MATLAB is used for simulation. The Solarex MSX60 PV module technical data sheet is referenced for modeling.
4：Experimental Procedures and Operational Workflow:
The algorithm involves six steps to rearrange PV modules based on their aging factors to achieve optimum configuration.
5：Data Analysis Methods:
The effectiveness of the proposed method is evaluated through computer simulation and analysis, comparing power outputs before and after reconfiguration.
