EV Power Management Incentives for Area-Based Demand Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The demand and supply of electric power vary significantly between different areas, making it challenging to effectively level them using conventional power management systems.
Innovation Solution
A power management system that facilitates the exchange of electric power between a power supply and demand system of an electric power trading partner and a vehicle, utilizing multiple charging and discharging apparatuses and a server to determine the optimal area for power exchange based on contribution to demand response, offering higher incentives for vehicles to move to areas with higher demand response contribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicles use charging apparatuses in their home areas for power exchange, then power exchange convenience is maintained, but demand response contribution remains insufficient due to localized power supply-demand imbalances
Solution Approach 1:
The server acts as an intermediary that coordinates between vehicles, charging apparatuses, and power supply-demand systems across different areas. It determines optimal power exchange locations, calculates demand response contributions, and manages incentive distributions, thereby enabling vehicles to contribute to demand response in areas other than their home locations without requiring complex direct coordination between all system components
Solution Approach 2:
The power management system is designed to handle multiple functions: managing power exchange between vehicles and power systems, determining demand response contribution across different areas, calculating incentives, and coordinating charging apparatuses. This multi-functional approach allows a single system to address various aspects of demand response without requiring separate specialized systems for each function
2Productivity
If the system provides uniform incentives for power exchange, then implementation simplicity is maintained, but vehicle motivation to move to high-demand areas is insufficient
Solution Approach 1:
The incentive amount is made variable based on the specific area where power exchange occurs and the vehicle's contribution to demand response in that area. Areas with higher demand response needs or greater impact from vehicle participation receive higher incentives, creating a differentiated incentive structure that motivates vehicles to move to and participate in high-demand areas while allowing centralized management through automated calculation
3Adaptability or versatility
If vehicles are encouraged to move to areas with high demand response contribution, then demand and supply leveling is improved, but system coordination complexity increases
Solution Approach 1:
The server continuously monitors power supply-demand conditions in different areas, calculates the demand response contribution of each vehicle based on its power exchange activities, and adjusts incentive amounts accordingly. This feedback mechanism guides vehicles to areas where their participation most effectively balances demand and supply, achieving adaptive coordination without requiring complex real-time communication between all system components

AI summary
A VGI system includes a plurality of BEVs, a plurality of pieces of EVSE, and a server. The server determines whether the BEV exchanges electric power with a power grid with the use of second EVSE provided in a second area, the second area being different in manner of management of power supply by the power grid from a first area where predetermined first EVSE is provided, the first EVSE being normally used by the BEV. When the server determines that the BEV exchanges electric power with the use of the second EVSE and when the second area is higher than the first area in contribution to DR in exchange of electric power by the BEV, the server grants an incentive higher than in exchange of electric power with the power grid with the use of the first EVSE.
