摘要

在微電網系統中，必須存在著發電系統、儲能系統、管理系統相輔相成來達成。在本論文裡著重於發電系統，先行假設儲能系統與管理系統已經穩定直流鏈電壓的情況下進行實現，並提出一套具強健性的多項式模糊控制法針對太陽能發電系統進行最大功率追蹤控制，觀察追蹤效率、電壓及電流輸出數據。而其結果將與傳統之擾動觀察法以及近期發展快速的T-S模糊控制法進行比較。
在硬體方面採用昇-降壓電路架構利用上述提及方法實現，一方面架構簡單純熟另一方面操作範圍較為廣泛。最後實驗結果比較其追蹤時間、電壓電流變動量、穩態準確率、追蹤準確率，並且分別以Psim軟體進行電路模擬、可程式直流電源供應器模擬實際大氣狀況以及實際接上太陽能光電板進行實驗，並驗證本論文所提方法的可行性。

In the micro-grid system, there must be power systems, energy storage systems and management systems to support each other. In this thesis focuses on the power system, first hypothesis the energy storage systems and management systems has stabilized DC bus voltage and presents a robust set of polynomial fuzzy control method for a solar power system maximum power tracking control, observation tracking efficiency, voltage and current output data. And the results will be compared with the traditional method and the recent rapid development of T-S fuzzy control method.
In terms of hardware using buck - boost circuit architecture using the above mentioned methods to achieve, one hand simple structure skillful on the other hand have extensive operating range. Finally, experimental results of its tracking time, the amount of change in voltage and current, steady-state accuracy, tracking accuracy, and respectively Psim software for circuit simulation, programmable DC power supply to simulate the actual atmospheric conditions and the actual solar panels connected to experiment, verify the feasibility of the proposed method.
