智慧能源站“多站融合”工程中交直流微网系统研究
Research on AC/DC micro-grid system in “multi-station fusion” project of smart energy station
This paper analyzed the traditional power supply mode and load characteristics of substations, data centers, energy storage stations, charging (replacement) power stations, etc., and the framework structure of AC/DC micro-grid power supply system in the project of "multi-station fusion" of smart energy stations is studied. According to study the deep integration of the energy storage unit and the design of the data center in AC/DC micro-grid, three power supply modes of energy storage unit applied to the data center server are proposed, and the wiring form suitable for DC micro-grid is proposed, which optimizes the configuration and operation mode of the diesel generators and the UPS system. On the premise of ensuring the reliability of the power supply of each system, the construction cost and operation costs are reduced, and the overall energy efficiency of the power system is improved, which provides a reference for the design and operation of “multi-station integration” projects of smart energy stations.
