Research on Key Design Points of DC Microgrid Architecture and Flexible Power Consumption for PEDF Buildings
Photovoltaic,Energy storage,Direct current and Flexibility(PDEF)new distribution system is an important path to achieving carbon neutrality in the building sector.To improve its application system,this study focuses on the"Direct"and"Flexible"aspects of the system,exploring the sub-item framework and detailed research objects of DC microgrid architecture and flexibility for the distribution system.Research was conducted on the technical significance,structural types,and application scenarios of individual modules to provide references for construction.The DC microgrid architecture includes four design points:DC power supply voltage level,DC microgrid mainline structure,DC microgrid network structure,and DC microgrid interconnection structure.The flexibility includes four design points:flexible load types,flexible load parameter settings,flexible energy storage capacity configuration,and flexible consumption strategy.Then,from the perspective of constructing nearly zero-energy buildings with PEDF systems,corresponding design priorities and suggestions were proposed for each design point.
