許多研究指出混合式再生能源比起單一能源來的更加有效率且可靠，獨立式混合再生能源系統可以應用在一些電網難以達到的地方，例如:山區或是破碎的小島。本篇論文模擬分析風力、太陽能以及電池混合再生能源系統，此系統加入最大功率追蹤及監控控制，以提升系統的效率及穩定性。風力機將採用永磁同步發電機，並利用Ćuk-SEPIC轉換器連接太陽能系統與風力系統。最大功率追蹤的方法採用模糊控制，並透過轉換器來達到最佳電壓。另外，為了提高電池壽命及增加系統的穩定性，將監測系統的電力供給量、負載量與電池的剩餘電量，以完成能源管理。整個系統模型的搭建以及模擬分析會在MATLAB/Simulink環境中進行。從結果的表現可以看出來，當風速或日照量改變時，模糊控制會使系統保持最大功率追蹤，且達到穩態。此外，當改變系統的電力供需量，能源管理會讓系統在最佳的模式運作。

Researchers of the renewable energy have often suggested that the hybrid renewable energy system (HRES) would be more reliable than only one power source. Standalone HRES is suitable for the region which is away from the main power grid. This thesis presents the configuration and control of the proposed HRES including solar energy, wind energy and battery storage. The solar system and the wind system with a permanent magnet synchronous generator (PMSG) are combined together using an integrated Ćuk-SEPIC converter. The proposed HRES applies maximum power point tracking (MPPT) technique to extract maximum energy. The voltages of the wind system and solar system are regulated by Ćuk-SEPIC converter with fuzzy logic MPPT method. In order to protect the battery and optimize system operation, the rule-based supervisory control in HRES is also applied. The proposed hybrid system with control is modeled and simulated using MATLAB/Simulink program. The simulation results show that the objective of MPPT control at varied wind speed and irradiance has reached. The performances of supervisory control are satisfactory under dynamic working conditions.
