The invention provides an energy management method and system for a multi-source access charging, replacing and storing integrated station. The method comprises the following steps: judging whether a photovoltaic module in the charging, replacing and storing integrated station allows to supply power to a power grid or not; when the photovoltaic module allows to supply power to a power grid, the output power of the photovoltaic module is adjusted to a preset minimum power limit value, and power control is performed on an energy storage module, a vehicle charging pile module and a battery replacement charging pile module in the charging, battery replacement and storage integrated station; when the photovoltaic module is not allowed to supply power to the power grid, the output power of the photovoltaic module is adjusted to a preset maximum power limit value, and power control is carried out on the energy storage module, the vehicle charging pile module and the battery replacement charging pile module at the same time; according to the invention, the priority of various energy inputs can be coordinated, photovoltaic power is used preferentially, energy storage is used in a peak period, a power grid is used again, and charging is carried out in a valley period, so that the utilization rate of new energy is improved, the electricity peak value of the whole station is reduced, and the load acceptance capability of the whole station is improved.

    本发明提供了一种多源接入的充换储一体站能量管理方法和系统,包括:判断充换储一体站中的光伏模块是否允许向电网送电;当所述光伏模块允许向电网送电时,将所述光伏模块的输出功率调整至预设的功率限制最小值,同时对所述充换储一体站中的储能模块、车用充电桩模块和换电充电桩模块进行功率控制;当所述光伏模块不允许向电网送电时,将所述光伏模块的输出功率调整至预设的功率限制最大值,同时对储能模块、车用充电桩模块和换电充电桩模块进行功率控制;本发明能够协调各种能源输入的优先顺序,优先使用光伏,其次高峰时段用储能,再次用电网,低谷时段充电,有利于提高新能源的利用率,降低整站的用电峰值,进而提高整站的负荷接纳能力。
