Abstract: In a power control system, a server transmits to each facility data generated by estimating a variation with time in power consumption in each facility and an upper limit value of power capable of being supplied to each facility. A HEMS controller calculates the sum of amounts of electric power consumed over an upper limit value on the basis of estimation data. A power conditioner reserves the power corresponding to the result of calculation in a storage battery in advance. The power conditioner supplies the power corresponding to the power storage capacity reserved in the storage battery to the facility in a case where the power consumption in the facility exceeds the upper limit value such that the upper limit of the power to be supplied from the system to the facility is set to the upper limit value.

Abstract: In a power control system, a control device acquires at least one of information about an external environment (result or predicted temperature) of a facility and information on a parameter associated with power consumption (production plan) in an internal environment of the facility and calculates a correlation between these pieces of information and actual consumed power. The control device predicts consumed power of the facility on the basis the correlation that is calculated and information such as predicted temperature and determines an upper limit set value of power supplied from an electrical grid to the facility on the basis of a result of the prediction. The control device supplies power charged in a storage battery to the facility when the consumed power of the facility exceeds the upper limit set value.
