本文提出一考量部分遮陰之太陽光伏發電系統全域最大功率追蹤，所提出之方法包含區間預測及跳躍(Prediction and Jump, P&J)之最大功率追蹤方法。首先在太陽光伏發電系統的某一電壓區間，亦即單片太陽能板之開路電壓值，取樣兩筆太陽光伏發電系統電壓與電流值後，搭配太陽光伏發電之特徵方程式，透過牛頓法可計算出當下氣候條件之太陽能電池數目與日照度，並推算出此時的區域最大功率點。再利用太陽能板I-V特性曲線呈現階梯狀之特性，及所提出之區域預測及跳躍最大功率追蹤點方法，在每次取樣更新各區間對應的太陽能電池數目與日照度後，重新預測各區域最大功率點後，跳躍到最可能的最大功率所對應的區間，然後重新執行計算直至確認全域最大功率點。實驗結果顯示本文所提方法對三種部分遮蔭測試樣本的最大功率追蹤精確度皆可達99.93%以上。

A Global Maximum Power Point (GMPP) tracking for Photovoltaic Generation Systems (PVGSs) considering partial shading is proposed in this thesis. A regional Prediction and Jump (P&J) method is also designed in this thesis to track the GMPP. Based on two measured voltages and currents in one voltage region of the open-circuit voltage of single photovoltaic panel and the characteristic output function of PVGS, the proposed method uses Newton-Raphson method to calculate the solar irradiance (S) and number of solar cells connected in series (N) directly. With S and N, the proposed regional P&J method will predict the possible voltage region and then jump to the possible voltage region. Two voltages and currents in the jumping voltage region will be measured and then S and N will be estimated again until the GMPP is tracked. Experimental results show that the maximum power tracking accuracy is more than 99.93% for three different partial shading cases.
