Design of AC and DC Power Supply System for Multi-Station Integration

摘要

With the advancement of the energy strategy, the construction of energy Internet based on the power grid, has become a popular direction in energy system integrative development. This paper studies the comprehensive energy hub in the process of the construction of energy Internet. Firstly, we study the load characteristics of the Internet date centers (IDCs), electric vehicle (EV) charging stations, 5G base stations and vehicle to grid (V2G) in the multi-station integration scenario; Secondly, according to the load characteristics of various loads, two topologies are designed, newly-built station and reconstructive station, for AC and DC power supply system. Also, we analyze the superiorities of the structures on power supply reliability and economy. Finally, we study the battery system fusion technology between the energy storage station and IDC’s uninterruptible power supply (UPS). The results may help engineers and researchers keep up with the progress of the multi-station integration clearly, as well as, it is of significant instruction for promoting the development of multi-station integration.
