摘要:	全球暖化、氣候變遷是需要長期投入改善的議題，氣候行動亦為聯合國永續發展核心目標之一，再生能源、儲能裝置、電動車等領域近年在技術與規模上快速成長，且在未來仍是重要的發展項目。電動車本身於行駛時有較低的碳排放，然而目前仍存在充電站未普及以及電力來源之碳排放較高的問題，本研究探討以最小化成本規劃太陽能隔音牆與儲能裝置之設置，以滿足服務區內電動車充電需求。根據充電需求規劃太陽能模組以及儲能裝置，進而降低電動車電力來源之碳排放量。本研究以最小化成本為目標，考量太陽能發電成本、儲能成本、購電成本及碳費，並根據相關數據如服務區充電需求、日射量與太陽能發電效率、太陽能隔音牆面積、可建置總面積等參數建立數學模型並求得最佳解。本研究於python中使用gurobi套件進行建模與求解。最佳解包含太陽能隔音牆之裝置容量、儲能裝置至儲能容量以及向外部購電之總電量。研究結果顯示，在裝設裝置容量為1.99MW的太陽能隔音牆、儲能容量為680kWh 的儲能裝置並向外部購電438,220度，得以最小化成本6,319,272元滿足一年當中服務區內電動車充電需求，並且以太陽能電力作為總使用電力之60%。實驗結果顯示在因春季與夏季日照強度較高，太陽能模組的發電量及使用率較高，可降低向外部購電的依賴並減緩夏季時的電網壓力。儲能裝置的使用上，主要於每日上午儲電，並於每日下午使用庫存電力供給。另外，本研究亦針對成本進行調整並分析，發現碳費的變動對總成本與使用太陽能使用率有較強的影響力，較高的碳費傾向有更高的總成本以及更高的太陽能使用率。;This research focuses on addressing global warming and climate change through sustainable solutions. It investigates the deployment of Photovoltaic Noise Barriers (PVNBs) and Battery energy storage system (BESS) to meet the charging demand of electric vehicles within a freeway service area. The objective is to minimize costs, considering solar power generation, energy storage, power purchase, and carbon pricing. A mathematical model is developed based on relevant data such as charging demand, solar radiation levels, solar power generation efficiency, size of PVNBs, and available installation space. The model is solved using Gurobi package in Python. The optimal solution includes the capacity of PVNBs, storage capacity of BESS, and the total electricity purchased from the grid. By installing PVNBs with a capacity of 1.99 MW, BESS of 680 kWh, and purchasing 438,220 kWh of electricity from the grid, the charging demand of electric vehicles within the service area can be met at a minimized cost of NTD 6,319,272 over a year. About 60% of the charging demand is powered by solar energy. Solar power generation and utilization are higher during the spring and summer. This reduces reliance on grid electricity and eases grid pressure during the summer. For BESS, the system mainly stores the surplus energy in the morning and uses it in the afternoon. The study also examines the cost sensitivity and reveals that changes in carbon pricing significantly impact the total cost and solar energy utilization. Higher carbon pricing leads to higher total costs and greater utilization of solar energy. Overall, this research provides insights into the optimal design of a solar-powered EV charging station. The results highlight the effectiveness of PVNBs and BESS in meeting charging demands sustainably and reducing reliance on the grid.
