獨立型太陽光發電系統的太陽電池匹配設計與充電增強技術研究

Abstract

本研究指在利用電容與鋰電池並聯，並聯接太陽板來進行充電研究，主要希望能透過這樣的方式來增強太陽能板鋰電池充電的發電量，提高充電的性能，研究內容包含了鋰電池的動態模型之系統識別、過去研究文獻模擬比較分析、以及戶外實際測試比對分析。 在研究中也提出了針對nMPPO系統匹配的性能指標，以協助在進行nMPPO系統匹配之太陽能板篩選時的依據。並透過這性能指標開發了一套圖型化使用者介面，讓在進行太陽能板篩選時能更加快速與比對。最後在透過戶外實驗，建立MPPT與nMPPO兩套系統進行比對測試，實驗結果顯示，nMPPO的發電效率最低的情況僅低於MPPT系統下5%左右，而在高累積發電量的情況，nMPPO系統的發電效率反而會超越MPPT系統的發電效率。

The research focuses on how to enhance charge performance of PV power generation system, for use in independent solar power system. Investigates increasing energy storage of PV power generation system by paralleling capacitor. Outdoor experimental results indicate that lithium battery in parallel capacitor system can improve the charge efficiency of PV power generation system. Then use effects of changes in radiation to explain why paralleling capacitor can improve the charge efficiency. In the research also proposed to explore nMPPO matching system performance to help match making system based nMPPO screening of the solar panels. Performance indicators through which developed a graphical user interface, making solar panels so that screening can be more quickly and comparison. Finally, through the outdoor experiments
