Micro-grid energy storage system

The invention aims to provide a novel micro-grid energy storage system, and the micro-grid energy storage system can improve the operation income of a charging station in an application scene of charging infrastructure construction in a non-populated area, thereby effectively motivating resource investment. The micro-grid energy storage system can also be used as distributed power grid frequency modulation and/or peak regulation equipment, so that the frequency modulation and peak regulation capability of an urban power grid is improved, and the construction and use cost of frequency modulation and peak regulation facilities is greatly reduced. The microgrid energy storage system comprises a power type energy storage module, an energy type energy storage module and a power management module, the power management module is used for power distribution, and the power distribution comprises first power distribution and second power distribution, and the electric power management module determines electric power u
