- 中文摘要: 在石化能源日益短缺且環保意識逐漸高漲下,本文提出了適用於一般住戶的一種乾淨、操作簡單的小型光伏發電系統,利用現有的簡單控制技術,將光伏能量取回給負載使用或直接饋送給電力系統。此架構包含一個昇壓式直流截波器和一個三相全橋式交-直流轉換器,前者主要將光伏能量傳送到直流電源端,而後者主要是用來補充光伏供應不足的能量給直流端負載,或將多餘的光伏能量傳送給電力系統。最後並實際製作一個光伏陣列最大功率為2.4KW的光伏發電系統,以驗證上述理論之正確性。
- 英文摘要: This paper describes a hybrid photovoltaic and battery energy storage system (PVBESS) whichconsists of a step-up chopper used to boost the solar panel voltage to a variable level and a current-modecontrolled bilateral converter used to transfer the energy between the PVBESS and utility. The proposedPVBESS operates in two modes:one is the parallel processing model, which can play a role as an activefilter, a power conditioner, or a voltage stabilizer; the other is the stand-alone mode, which acts as aconventional uninterruptible power supply. The basic principle from the conventional control methodis used and modified to develop the desired operation function. The proposed theoretical formulationsare verified by system analysis and simulation to demonstrate its performance. A laboratory prototypehas been fabricated and tested to support the proposed idea of a multifunction PVBESS.
