  • Patent number: 11868149
    Abstract: 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.
