Problems solved by technology

However, if the security level of the aggregator is insufficient, personal information may not be leaked from the aggregator
In the case of leakage of personal information held by the aggregator, the loss may be large when the number of vehicles participating in V2G is large

Embodiment Construction

[0061] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0062] A V2G (Vehicle to Grid) system is a system that integrates electric power between an electric power system including a commercial power grid and an electric vehicle, and when the electric vehicle is not used as a moving mechanism, the battery mounted on the electric vehicle is used as electric power storage device. Therefore, two-way transmission and reception of electric power is performed between the electric vehicles participating in V2G and the electric power system.

[0063] Electric vehicles participating in V2G perform continuous discharge for the purpose of maintaining the balance between supply and demand in the power system, or perform charge and discharge for the purpose of stabilizing the frequency in the power system according to the status of the power system. Electric power obtained by continuous discharging or continuous charging of an electric v...

Abstract

The invention provides a V2G system for preventing information leakage, a server device, and a conveying facility. The V2G system comprises a parent aggregator which manages buying and selling of power from a plurality of power supply sources to a power grid, and a child aggregator which manages a plurality of transport machines and guarantees the parent aggregator charging and discharging betweenat least one of batteries mounted on the transport machines and the power grid. The child aggregator acquires first information regarding the charging and discharging and second information regardingthe transport machines from each of the transport machines, aggregates the first information and the second information, and transmits at least the first information to the parent aggregator.

Description

technical field [0001] The present invention relates to a V2G system, a server device, and a transmission facility in a V2G (vehicle-to-grid) capable of bidirectional electric power exchange (supply and reception) between a storage device installed in a transmission facility and an electric power system. Background technique [0002] In V2G, which enables two-way transmission and reception of electric power between the power system including the power grid and vehicles such as EVs (electric vehicles), a server called an aggregator that integrally manages the charge and discharge of the accumulator included in the vehicle plays an important role. role. The aggregator is connected to each vehicle via a communication network, and instructs the vehicle to charge and discharge to and from the grid based on information about each vehicle and the state of supply and demand of electric power in the power system. Patent Document 1 discloses an aggregator that notifies the power syst...
