日射量容易受天氣因素影響而產生突坡事件,並造成太陽能發電量不穩定,以致難以將其整合入區域電網當中。本研究以全天空影像儀捕獲白晝之全天空影像,並建立一以影像特徵為基礎之日射量及太陽能發電量估算與預測系統。分析當前空影像以萃取全域及局部雲層之權重;利用光流法推算雲層移動狀態,並製作一分鐘之天空預測圖像。將雲層權重作為長短期記憶(LSTM)之輸入,以進行日射量估算與預測。並且,製作功率曲線,以進一步估算太陽能之發電量。本研究使用多個效能指標評估效果,包括平均絕對誤差(MAE)、均方根誤差(RMSE)、正歸化均方根誤差(nRMSE)以及判定係數(R^2);並設計數個實驗方法進行比較,實驗結果顯示,本研究所提出方法具有較佳的性能。
