建筑“光储直柔”系统中直流家用电器技术及标准进展研究

With the deepening of the energy revolution，the power terminal will also usher in new changes，DC household appliances in building“photovoltaic-energy storage-direct-flexibility（PEDF）”system have typical features-storage and use integration，DC power supply and flexible electricity consumption. This paper focuses on the technologies and standards of DC household appliances，compares the relevant standards at home and abroad. Thus，a standard system for DC household appliances was built based on the above review，the key technologies that hinder the industrialization of DC household appliances were analyzed，and the key research contents of technical standards were proposed. Conclusively，the outlook of the future research was proposed to provide reference for further in-depth research and exploration of "PEDF" DC household appliances.
