A server device includes a processor and a memory storing a program executed by the processor. The processor is configured to accept a tender for a transaction of electricity transfer in a parking lot, contract the transaction of electricity transfer corresponding to the tender, and perform charge control for charging at least one vehicle out of a plurality of vehicles located in the parking lot, the at least one vehicle having placed the tender.

Server device and electricity transaction system

A market electric power price predicting unit predicts a trading price of electric power traded in a P2P electric power trading market. The trading price includes a price of renewable energy electric power and a price of non-renewable energy electric power. A renewable energy index setting unit sets a renewable energy index indicating a degree of the renewable energy electric power in electric power purchased in the P2P electric power trading market. A trading price setting unit sets a desired trading price in an electric power trading plan from a prediction result of the trading price of the electric power and the renewable energy index. A trading plan creating unit creates the electric power trading plan based on the desired trading price.

Information processing device

An automatic bidding system includes a vehicle agent (a computer). A vehicle agent includes a bidding agent (a bidding unit) that places an automatic bid for power trading related to electric power of a user in accordance with an automatic bidding algorithm, and an information collection agent (an information collection unit) that acquires user information indicating a preference of the user. The bidding agent is configured to set a parameter of the automatic bidding algorithm using the user information.

Automatic bidding system and automatic bidding method for power trading

A power trading system includes a power trading platform (a power trading computer) and a vehicle agent (a bidding computer) that places a bid on the power trading platform. The vehicle agent includes a bidding unit and a generation unit. The bidding unit places a bid for power trading by transmitting bid data in a predetermined format to the power trading computer. The generation unit transcribes transcribed information included in the bid data for a contracted bid and generates the bid data for a cancellation bid so as to cancel the contracted bid. The transcribed information includes attribute information indicating an attribute of electric power related to power trading.

In a power transmission and distribution system, each charging and discharging apparatus includes a communication unit configured to receive information on charging and discharging requirement amounts of at least one other charging and discharging apparatus. In each charging and discharging apparatus, according to an average agreement calculation of a multi-agent system, agreement values obtained by dividing, by the number of agents, a total of charging requirement amounts and a total of discharging requirement amounts of all charging and discharging apparatuses, respectively, is calculated using own charging and discharging requirement amounts and information on the charging and discharging requirement amounts of the other charging and discharging apparatus acquired by the communication unit, and a limit amount on a charging execution amount or a discharging execution amount of each charging and discharging apparatus is controlled based on the agreement values.

Method and system of controlling chargeable and dischargeable power amounts of charging and discharging apparatus group in power grid

A system includes a plurality of control devices that respectively control the states of a plurality of apparatuses and are connected to each other via communication lines. When each of the control devices determines a state target value of its own apparatus using the current state indicator value of the own apparatus, and the distributed controller input which is a function of the state indicator value of an apparatus adjacent to the own apparatus and the state indicator value of the own apparatus, the control gain which adjusts contribution of the distributed controller input to the state target value is determined based on a communication delay time between the control devices.

Distributed control system

A distributed control system includes a plurality of control units that controls respective units of a plurality of devices, and a communication network that includes a communication line that connects the control units. A control unit of each of the devices is configured to determine a state target value, according to consensus control of a multi-agent system, by using a current state index value of a self-device, and a difference between a latest state index value of an adjacent device received from a control unit of the adjacent device, and a latest state index value of the self-device received from the control unit of the adjacent device.
