Engineering Contradiction Analysis
1Quantity of substance
If a virtual power plant is configured using a large number of battery electric vehicles, then the scale of electric power exchange is increased, but it becomes difficult to predict and adjust the supply and demand of electric power
Solution Approach 1:
The patent segments the large number of battery electric vehicles into multiple vehicle groups based on their electric power supply and demand characteristics. Each vehicle group is managed separately with aggregated characteristics, allowing the system to handle large-scale participation while maintaining predictability through standardized group-level parameters rather than individual vehicle variability.
Solution Approach 2:
The patent changes the management parameter from individual vehicle-level characteristics to aggregated vehicle group-level characteristics. By configuring vehicle groups such that their distributions of electric power supply and demand characteristics are the same or similar, the system transforms complex individual variations into manageable uniform parameters that facilitate accurate prediction and adjustment.
2Ease of operation
If electric power exchange is managed for each individual vehicle, then detailed control is achieved, but the complexity of prediction and adjustment increases significantly
Solution Approach 1:
The patent merges multiple individual vehicle management tasks into a single vehicle group management framework. By bundling vehicles with similar characteristics into groups and managing the exchange of electric power at the group level rather than individual level, the system significantly reduces operational complexity while maintaining effective control through aggregated parameters.
Solution Approach 2:
The patent creates universal vehicle group configurations that can be applied across different sets of vehicles with similar characteristics. The standardized group management approach allows the same management procedures and prediction methods to be universally applied to multiple vehicle groups, reducing the need for vehicle-specific management complexity.

AI summary
An electric power management system is a system that performs an exchange of electric power with an electric power system of an electric power company that is a counterparty of the exchange of the electric power, and includes a plurality of the vehicles, each including a battery, and a server that manages an exchange of the electric power between the battery of each of the vehicles and the electric power system. The server manages the exchange of the electric power for each vehicle group in which the vehicles are bundled, and configures the vehicle groups in advance such that distributions of the electric power supply and demand characteristics of the batteries of the vehicles included in the vehicle groups are the same or similar.
