Zusammenfassung:The invention discloses an energy conservation control method and system based on a microgrid. The method comprises the steps of detecting a time interval of current time and inquiring a correspondence list between the time interval and a power utilization period to obtain a current power utilization period; obtaining the load power of a current user side, the output power of the microgrid and the electric quantity in a power storage device; judging whether the output power of the microgrid is larger than the load power of the current user side in a power utilization peak period; if on yes judgment, giving priority to charging the power storage device under the condition that the microgrid can meet a user load; if on no judgment, preferably utilizing the microgrid and the power storage device to supply power. According to the energy conservation control method and system based on the microgrid, the power supply object of the microgrid and the charge-discharge state of the power storage device are adjusted and
