The EMS control command is transmitted to another device by the transmission / reception module so that the device can restrict the use of electric power. This EMS control command can also be applied to the apparatus 340 including the peak power control module.

The peak power control module can limit the grid power usage of multiple devices only at the peak time limit. The peak power in the grid is produced by the high-price generator, and the power generation efficiency is low, and it is also temporarily developed to make the grid unstable. This peak power occurs because individual customers receiving power from the grid make peak power at the same time, respectively. If peak power is produced only in one customer in a time zone where peak power is not generated in another customer, there is no big problem in the whole system. For this reason, the peak power control module can limit the grid power usage only at the peak time zone where the customers receiving power from the grid are likely to make peak power together.

The system power control apparatus 620 transmits a control command to the power consuming apparatus to adjust the power demand is called a demand response.

The demand reaction control module receives the demand reaction control command from the grid power management unit 620 and, when the demand response control command includes information that the power consumption is reduced, the power demand for the controllable unit Use EMS control command or power-off EMS control command can be calculated.

The power cost control module calculates the discharge EMS control command for the energy storage device included in the energy management system at the high price time zone according to the hourly power unit price data and calculates the charge EMS control command for the energy storage device at the low price time zone .
