ELECTRIC POWER CONTROL SYSTEM, CONTROL DEVICE, AND METHOD FOR CONTROLLING ELECTRIC POWER

摘要

Provided is an electric power control system for enabling electric power supplied from a grid to be effectively utilized without placing an excessive load on the power distribution network of the grid. In this electric power control system (1), a control device (10) acquires from an electronic breaker (850) a current measurement value, which is information relating to the electric power supplied by the grid to loads of a facility, and the rated current value of the electronic breaker (850). The control device (10) compares the current measurement value with the rated current value in order to measure an excess period during which the current measurement value exceeds the rated current value, causes the electric power from the grid to be supplied to the loads until the excess period reaches a given period of time which is defined on the basis of the current measurement value, and causes electric power charged in a storage battery (830) to be supplied to the loads when the given period of time is reached in order to reduce the load on the distribution network of the grid. The electronic breaker (850) is preset to interrupt current within a predetermined operating time when current higher than the rated value has flowed therein. The length of the given period of time is based on the operating time.
