A power control system and method for suppressing purchase power peaks or controlling surplus power household consumption according to changes. The power control system comprises a monitoring unit, an electricity storage quantity acquisition unit, and an electricity storage controller. The monitoring unit monitors a generated power quantity which an electricity generator generates using renewable energy and a purchase power quantity which a consumer purchases via a power grid. The electricity storage controller executes processes of discharging power from an electricity storage cell if the purchase power quantity is greater than or equal to a first threshold value; charging the storage cell if the generated power quantity is greater than zero and the purchase power quantity is less than or equal to a second threshold value less than the first threshold value; and charging and discharging the storage cell such that the acquired electricity storage quantity reaches a target value.

Power control system and power control method

A power storage control system reduces the operating cost in a power storage system, and comprises a monitoring section and a charge/discharge control section. The monitoring section monitors a prescribed index value that correlates with the degradation degree of a storage battery for each storage battery included in a plurality of power storage systems. The charge/discharge control section controls the period in which the prescribed index value of each storage battery changes to a prescribed value by degradation accompanying charging and discharging of the storage battery, by performing control relating to at least one of the charge amount or the charge/discharge speed in charging and discharging of the storage battery based on the monitoring results of the monitoring section.

Power storage control system and power storage control method

A power control system, which enables more effective utilization of electrical power generated by using renewable energy, includes a monitoring unit, an output control unit, and a power storage control unit. The monitoring unit monitors the amount of electrical power generated by a power generation device using renewable energy and the amount of electrical power purchased by a consumer through utility grid. When the amount of purchased electrical power is less than a first threshold on the basis of a monitoring result of the monitoring unit, the output control unit suppresses output of electrical power generated by the power generation device. When the amount of the purchased electrical power is less than a second threshold which is greater than the first threshold on the basis of the monitoring result, the power storage control unit charges a storage battery with the generated electrical power outputted by the power generation device.
