The invention discloses a direct-current micro-grid system based on a virtual power plant. The direct-current micro-grid system comprises a micro-grid direct-current bus, a photovoltaic power generation system, an echelon battery energy storage system, a lithium battery energy storage system, a charging station, a direct-current load, a charging station edge calculation terminal, a flexible load edge calculation terminal and a micro-grid management and control system. According to the DC micro-grid system based on the virtual power plant, the micro-grid management and control system controls the charging pile and the flexible load in the charging station through the charging station edge calculation terminal and the flexible load edge calculation terminal; the data interaction mode among the charging station edge calculation terminal, the flexible load edge calculation terminal and the micro-grid management and control system does not change along with the change of the type and the capacity of the charging pile/flexible load, so that even if the charging pile and/or the flexible load are/is changed, the data interaction mode is not changed. And a new application scene requirement can be adapted without re-developing and re-modifying the micro-grid management and control system, so that the development workload of the system is reduced.

    本发明公开了一种基于虚拟电厂的直流微电网系统,其包括有微电网直流母线、光伏发电系统、梯次电池储能系统、锂电池储能系统、充电站、直流负荷、充电站边缘计算终端、柔性负荷边缘计算终端及微电网管控系统。上述的基于虚拟电厂的直流微电网系统,微电网管控系统分别通过充电站边缘计算终端、柔性负荷边缘计算终端对充电站内充电桩以及柔性负荷进行控制,充电站边缘计算终端、柔性负荷边缘计算终端与微电网管控系统之间的数据交互方式不随充电桩/柔性负荷的类型、容量改变而改变,故而,即使充电桩和/或柔性负荷发生了变化,也无需对微电网管控系统进行重新开发修改就可适配新的应用场景要求,减少了系统的开发工作量。
