Abstract: A power dispatch system and a power dispatch method are provided. When a time span of the historical electricity usage data is greater than or equal to a preset value, an upper bound is determine according to the historical electricity usage data, the expected power demand and a dispatchable power. When the time span is less than the preset value, the upper and lower bounds are determined according to the historical electricity usage data.

When the actual power demand is less than the lower bound, the power system receives an amount of power equal to the lower bound, and the energy storage unit receives the surplus power for charging.
