Assignee: KANEKA CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC G  H  Y | IPC G  H

Claim 1:
2. A power control system comprising:
a monitor configured to monitor a generated electrical power amount which is generated by a power generator using renewable energy and a purchased electrical power amount purchased by a consumer via an electric power grid;
an output controller configured to suppress generated electrical power outputted by the power generator, upon determining that the purchased electrical power amount falls below a first threshold, based on monitoring results of the monitor, the first threshold being set to a value such that reverse power flow to the electric power grid does not occur;
a storage power controller configured to perform charging to a storage battery by the generated electrical power outputted by the power generator, upon determining that the purchased electrical power amount falls below a second threshold which is a threshold greater than the first threshold, based on monitoring results of the monitor, the second threshold being set to a value such that purchased electrical power does not arise even if performing charging to the storage battery;
a power conditioner configured to supply generated electrical power which is outputted by the power generator to a load apparatus;
a convertor configured to output generated electrical power which is outputted by the power generator by converting into voltage suited to the storage battery, when the electric power grid has power outage; and
a path management device configured to perform charging to the storage battery, by forming a supply path for supplying, to the storage battery, generated electrical power after conversion outputted by the convertor, when the electric power grid has power outage.
