臺灣博碩士論文加值系統

　　本文首先說明日射量機率模型的建立方法，求得逐時日射量資料，提供太陽光伏電力系統模擬之用。其次說明獨立光伏電力系統各組件的特性，建立獨立光伏電力系統模型。本文採用交通部中央氣象局台南氣象站所提供，1994至1998年的逐日日射量與溫度資料作為模型的輸入數據，選擇「年累積缺電時數」(LOLH) 與「年累積缺電量期望值」(EENS) 作為電力系統之供電可靠度指標，以數值模擬法評估太陽能電池模組容量、蓄電池容量、供電可靠度三者間的關係，並改變系統參數，觀察環境變因、負載參數、及太陽能電池仰角對系統供電可靠度之影響。最後，說明系統供電可靠度用於尋求系統最佳容量的方法。研究的結果除供電可靠度與最佳容量外，亦可提供日射量的接收情形、光伏電池發電量、蓄電池端電壓、蓄電池充／放電流及蓄電池放電深度等系統重要參考指標。

　　This thesis begins with probabilistic modeling of solar radiation for simulating hourly insolation. This is followed by modeling of components of a stand-alone photovoltaic (PV) system for whole system dynamic simulation. The daily solar radiation data from 1994 to 1998 provided by the Central Weather Bureau are taken as inputs. The Loss of Load Hours (LOLH) and the Expected Energy Not Served (EENS) are chosen as reliability indices of the PV power system. The dynamic simulation gives the relation between PV module capacity, battery capacity and reliability indices, and shows the effects of system parameters, environment, load parameters and PV module tilt angle on the system performance. The simulation is useful for reliability evaluation and optimal sizing. It also provides important information on energy conversion performance, generated energy, battery terminal voltage, charge/discharge current and depth of discharge of battery.
