Information to be displayed on a display is generated in such a way that a gateway processes a measured value (with a time stamp) transmitted from a power meter, an appliance monitor, a solar module, and a battery center through a wireless LAN. In the gateway, information relating to the consumed electric energy is synchronized with each other by the time stamp. Further, an integrated value of the consumed electric energy is calculated with respect to time. The information can be secured by obtaining the integrated value of data even if breakdown of devices and the like occurs due to power failure.

Power control device and power control method

Control of supplying power to a storage device is performed based on carbon emission strength or a power rate. A battery centerthat constitutes a storage deviceperforms radio communication with a gatewayand is controlled by the gateway. The gatewaycollects a measured value of power consumed by electric appliances in a home and obtains the carbon emission strength in real time. A solar panelis provided and a battery of the storage deviceis charged with an output of the solar panel. The battery is also charged with direct current power obtained from power from outside. The power is stored in the storage devicebased on the carbon emission strength by charging control.

To solve problems arising when a power conditioner equivalent to that connected to a solar panel is connected to a power storage device. Direct-current power generated by the solar panelis supplied to a DC-DC converterand output as a predetermined direct-current voltage. The output voltage of the converteris supplied to a DC-AC inverter. Direct-current power generated by the power storage deviceis supplied to a DC-DC converter. Predetermined direct-current power from the converteris supplied to a DC-AC inverter. Alternating-current power output by the inverteris supplied to an alternating-current power system at home. The converteris configured to have two output voltages. The first output voltage is a standby voltage. The second voltage is a voltage at which the inverterstarts power supply to outside.
