Construction of Low Voltage DC Smart Buildings with Generation-Storage-Distribution-Utilization

In order to achieve the goal of “carbon peak and carbon neutralization”, this project has established a set of building low-voltage DC power distribution system, including roof DC parallel grid distributed photovoltaic system, DC power loads, etc.The mode of “DC source-network-load” is adopted to realize the organic integration of DC power grid and new energy, which not only creates a safe, intelligent, reliable and efficient power consumption environment for users, but also realizes the improvement of energy efficiency.The paper can play a demonstration role in the research of low-voltage DC distribution related topics, and accumulate a lot of construction experience and actual operation data for DC smart building.
