V2G Power Source Control for Fair Participation Incentives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a vehicle-to-grid (V2G) system, the current incentive structures either lead to a decrease in participation ratio due to unfairness perceptions among non-participating registered users or result in insufficient electric power supply when incentives are only granted to actual participants.
Innovation Solution
A controller is implemented that determines the number of actual participants capable of supplying electric power and adjusts the output of each participant to ensure a uniform electric energy contribution to the grid, thereby increasing participation registration and ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If incentives are granted to all registered participants regardless of participation, then the incentive distribution is simplified, but the participation ratio decreases because users feel unfairness when non-participants receive the same incentive
Solution Approach 1:
The patent applies local quality by differentiating incentive treatment between two distinct user groups: registered participants and actual participants. Instead of uniform incentive distribution, the system provides different incentive levels to different subsets of users based on their actual participation status, thereby maintaining fairness perception while simplifying the overall incentive structure.
2Reliability
If incentives are only granted to users who actually participate, then the participation ratio increases due to fairer incentive distribution, but the number of registered participants decreases because users may register but not participate
Solution Approach 1:
The patent segments the user base into two distinct categories: registered participants (who have expressed intent to participate) and actual participants (who have actively participated). By providing incentives to both segments, the system maintains a large pool of registered participants while ensuring high participation ratios among actual participants, thus resolving the contradiction between quantity and reliability.
3Device complexity
If participation registration and participation ratio decrease, then the incentive distribution complexity is reduced, but the electric power and electric energy that can be supplied to the electric system decrease
Solution Approach 1:
The patent implements a feedback mechanism where the control device monitors participation status and dynamically adjusts incentive distribution. By providing incentives to both registered and actual participants, the system maintains high participation rates, which in turn ensures sufficient electric power supply capacity to the electric system, preventing the negative feedback loop where reduced participation leads to reduced supply capacity.

AI summary
A controller according to an embodiment includes a determiner and an output controller. The determiner determines a number of participants representing a number of electric power sources that are able to actually participate in supplying of electric power to an electric system. The output controller causes each of the electric power sources that are able to actually participate in the supplying to output, to the electric system, an electric energy determined by dividing a predetermined electric energy by the number of participants. The controller according to the embodiment may further include a granter. The granter grants an incentive to users who use the electric power sources that actually participate in the supply.
