1. An energy system in a community provided with a plurality of unit grids,
wherein each of the unit grids is an energy transfer network of a single-unit facility including a power load that consume power,
wherein each of the unit grids include a renewable energy power generator that generates power using renewable energy and supply the power generated by the renewable energy power generator thereof to the power load thereof,
wherein each of the unit grids forms, as an electric vehicle moves, a cooperative grid that transfers power stored in a mobile storage battery, which is a storage battery mounted on the electric vehicle, to and from another of the unit grids,
wherein some of the unit grids whose geographical positional relationship is not fixed form a virtual grid for transferring power as a combination of the unit grids that form the cooperative grids changes in accordance with a destination of the electric vehicle,
wherein the unit grid of which the facility is a general house further includes a heat load that consumes heat, a heat storage apparatus that converts the power into heat and stores the heat, an uninterruptible power supply that is a stationary storage battery in the facility, a control apparatus that performs energy transfer adjustment,
wherein the control apparatus controls transfer of power through a current path for performing at least (A) supply of power to the power load from the renewable energy power generator, (B) supply of power to the heat storage apparatus from the renewable energy power generator, (C) supply of power to the mobile storage battery from the renewable energy power generator, or (D) supply of power to the uninterruptible power supply from the renewable energy power generator on a basis of detection of numerical data including an amount of power generated by the renewable energy power generator, power demand of the power load, heat demand of the heat load, an amount of heat stored in the heat storage apparatus, an amount of power stored in the mobile storage battery, and an amount of power stored in the uninterruptible power supply, and
wherein the control apparatus controls such that (A) has the highest priority among (A) to (D), (D) has the lowest priority among (A) to (D), and the control apparatus does not control the supply of power from the uninterruptible power supply to the mobile storage battery.
