With the widespread installation and use of distributed photovoltaic power generation in civilian buildings,how to rationally and efficiently utilize the direct current generated by photovoltaic power generation is a new direction of exploration for green buildings in the electrical application end.The"photovoltaic storage direct and soft"system integrates distributed energy sources such as photovoltaic and energy storage with building electrical distribution directly,forming an independent microgrid,achieving"direct generation and direct use",and improving the utilization efficiency of distributed energy.This paper shares the actual design scheme and theoretical support of the"photovoltaic storage direct and soft"system in a headquarters office building electrical system design as an example.At the same time,it analyzes the technical difficulties faced in its application in buildings and the corresponding solutions.
