This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2020-058022 filed on Mar. 27, 2020, the content of which is incorporated herein by reference.
This invention relates to a power calculation apparatus and a power calculation method predicting and calculating an amount of power suppliable to a power grid.
As such an apparatus of this type, a conventionally known apparatus calculates the amount of power suppliable to a power system from factories and various facilities, and controls the supply-and-demand balance of power based on the calculated amount of power (see, for example, WO2015/019585A1).
The objects, features, and advantages of the present invention will become clearer from the following description of embodiments in relation to the attached drawings, in which:
FIG. 1 is a diagram schematically showing a power system to which a power calculation apparatus according to an embodiment of the present invention is applied;
FIG. 2 is a diagram showing an exemplary functional configuration of the power calculation apparatus according to an embodiment of the present invention;
An embodiment of the present invention will be described below with reference to FIGS. 1 to 7. A power calculation apparatus according to the embodiment of the present invention is an apparatus provided between a predetermined energy source capable of generating or storing power, especially a battery mounted on a vehicle such as an electric vehicle (EV), and a power grid, and calculates power for transfer between the predetermined energy source and the power grid. Hereinafter, the power grid may be simply referred to as a grid. In addition, in the following, when simply expressed as a vehicle, the vehicle means an EV.
Recently, the effective utilization of renewable energy has been promoted due to the increase in greenhouse gas emissions. As one of the effective utilizations, a Vehicle to Grid (V2G) system has been proposed, in which EVs are connected to a power grid and the energy stored in the batteries mounted on the EVs is utilized effectively.
In such a V2G system, the EVs not only receive power supply from the grid to charge the batteries, but also supply the power stored in the batteries to the grid, resulting in making the batteries function as if the batteries were one of the power storage facilities in a commercial power grid. As described above, in the V2G system, not only one-way power supply from the power grid to the EVs, but also two-way power transfer including power supply from the EVs to the power grid are performed.
