Abstract
Upon power failure of a commercial power source, an automatic switching device switches to power supply from a hybrid vehicle. An ECU of the vehicle, when receiving a request for generation of a commercial AC voltage, sets an upper-limit power generation amount based on a remaining amount of fuel. The ECU transmits the upper-limit power generation amount via an antenna to an on-premises ECU, while controlling a power generation amount based on the upper-limit power generation amount. The on-premises, when receiving the upper-limit power generation amount, controls the load state such that commercial AC power is supplied firstly to a first load of priority level 1, according to proprieties registered in advance, and such that the amount of the power supplied to the electric loads does not exceed the upper-limit power generation amount.
