Claim 18:
19. A power control method executed by a power control system, the method comprising:
monitoring a generated electrical power amount generated by a power generator using a renewable energy, and a purchased electrical power amount purchased by a consumer via an electric power grid;
suppressing generated electrical power outputted by the power generator, when a determination is made that the purchased electrical power amount falls below a first threshold, based on monitoring results of a monitor, the first threshold being set to a value such that reverse power flow to the electric power grid does not occur;
performing charging by a power storage controller on a storage battery by generated electrical power outputted by the power generator, when a determination is made 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;
isolating, by a switch, the power generator from an electric power grid when the electric power grid has power outage;
outputting, by a convertor, 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
performing charging to the storage battery, by a path management device, 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.
