Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0044] V2G (Vehicle-to-Grid) is a system that integrates electric power between a power system including a commercial power grid and an electric vehicle. When the electric vehicle is not used as a moving mechanism, the battery mounted on the electric vehicle is used for power storage. equipment. Therefore, two-way transmission and reception of electric power is performed between the electric vehicles participating in V2G and the electric power system.

[0045] figure 1 is a diagram showing the overall configuration of the V2G system. Such as figure 1 As shown, the V2G system includes: a power system, which is composed of a power station 11 that generates power through thermal power, wind power, atomic energy, or sunlight, and a power transmission network 12 that includes power generated by the power supplier of the power station 11; Users 13, who need electricity an...

Abstract

The charging / discharging device includes: an electric storage device installed in the transportation facility; a power conversion unit that converts electric power exchanged between the storage device and an external power system; and a control unit that controls the operation of the power conversion unit based on a received signal. The server device that manages the charging and discharging of the electric storage device predicts the supply and demand of electric power in the electric power system, determines the time for discharging the electric storage device to the electric power system or the time for charging the electric storage device with the electric power supplied from the electric power system, and includes the determined A command of the time to discharge or charge is sent to the charging and discharging device.

Description

technical field [0001] The present invention relates to a server device in a V2G (Vehicle to Grid) capable of bidirectional power transfer (supply and reception) between a storage battery installed in a transmission facility and an electric power system. Background technique [0002] Patent Document 1 discloses a charging system for a vehicle that has a timer function in order to make charging reservations possible. Charging starts at the start of charging. In this charging system for a vehicle, when an abnormality occurs in the timekeeping function of the clock function unit for keeping time, the control unit judges whether the state of the normal mode can be maintained based on the power remaining amount of the 12V system battery and its own power consumption. Continue to start until charging starts. Then, when it is determined that the startup can be continued, it waits in the normal mode until the charging start time. [0003] In addition, Patent Document 2 discloses ...
