摘要:

 “光儲直柔”建筑新型能源系統是面向碳中和目標實現建筑能源系統革新的重要技術路徑。本文對其關鍵環節的構建提出了基本認識:在建筑光伏利用中應當充分利用建筑自身表面資源,并根據建筑類型區分;需要重新認識建筑中各類可視為儲能的資源,挖掘建筑側的儲能潛力;根據需求設置直流配電系統并實現有效的系統柔性調節。對現有“光儲直柔”建筑案例進行了簡要介紹,并對未來需開展的研究進行了展望,以期為“光儲直柔”的進一步深入研究、探索提供參考。

關鍵詞:光儲直柔;系統構建;建筑等效儲能;建筑柔性;研究展望

Abstract:

PEDF (photovoltaics, energy storage, direct current and flexibility) is a kind of novel building energy system towards carbon neutrality. It is an important technical path to realize building energy system innovation under the goal of carbon neutrality. In this paper, the basic understanding of the construction of the key links is put forward, where it should make full use of its own surface resources in the utilization of building photovoltaic, and distinguish according to the building type. It is necessary to re-understand all kinds of resources that can be regarded as energy storage in buildings and tap the potential of energy storage in buildings, and to set up DC power distribution system according to requirements and realize effective system flexibility adjustment. The existing cases of PEDF buildings are briefly introduced, and the future research is prospected, in order to provide references for further research and exploration of the PEDF buildings.
