摘要

本研究旨在探討隔離混合型太陽光發電系統最佳化設計，並以實作去驗證模擬結果及證明系統的實用性。隔離混合型太陽光發電系統乃本研究所創新設計的系統概念，採太陽能模式或市電模式獨立對負載供電，首先建立系統模型，再以長程模擬得知採Fuzzy控制的供電切換控制具有最佳系統性能。針對不同的地區及負載，以模擬結果討論出系統太陽能板及蓄電池的最佳設計值，並以此最佳值實際架設一套隔離混合型太陽光發電系統，經長期實驗數據證明，採用nMPPO技術及隔離切換供電的隔離混合型太陽光發電系統，具有高發電效率、供電穩定及高經濟效益。

This study is aimed to discuss the isolated-hybrid solar PV system optimal design, verifying the simulation results by implementation and prove the system practicality. Isolated-hybrid solar PV system is an innovative design that is powered by solar mode or grid mode. First derive the system's models and then by long-term simulation find out when using Fuzzy control in power switching control could have the best performance. For different reigns and loads, we obtain the optimal installed capacity of PV and battery with the simulation results and set up an isolated-hybrid solar PV system with the optimal design. The long-term experimental data show that the solar PV system with nMPPO technique and isolated switching power supply have a high power generation efficiency, stable power supply and high economic efficiency.
