Development statuses and research prospects of PEDF (photovoltaics,energy storage, direct current and flexibility) building energy systems
摘要：
“光储直柔”建筑新型能源系统是面向碳中和目标实现建筑能源系统革新的重要技术路径。本文对其关键环节的构建提出了基本认识：在建筑光伏利用中应当充分利用建筑自身表面资源，并根据建筑类型区分；需要重新认识建筑中各类可视为储能的资源，挖掘建筑侧的储能潜力；根据需求设置直流配电系统并实现有效的系统柔性调节。对现有“光储直柔”建筑案例进行了简要介绍，并对未来需开展的研究进行了展望，以期为“光储直柔”的进一步深入研究、探索提供参考。
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.
