DR Mobility Server for Alternative Vehicle Availability Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of vehicles equipped with power storage devices for demand response (DR) in power grids limits user mobility during DR periods due to external charging, reducing convenience for users.
Innovation Solution
A server system that notifies users of alternative mobile objects available in the vicinity of the DR location, allowing users to utilize these objects during DR periods, and optionally adjusts vehicle charging to facilitate early termination of DR participation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle participates in DR through external charging during the DR period, then the electric power demand-supply balance is adjusted, but the user cannot move from the DR location by driving the vehicle, reducing convenience for user movement
Solution Approach 1:
The server acts as an intermediary that provides alternative mobile object information to users during DR periods. When a vehicle is engaged in external charging for DR, the server queries and notifies users of available alternative mobile objects (such as other vehicles or transportation options) in the vicinity of the DR location, enabling users to maintain mobility while the vehicle participates in DR
Solution Approach 2:
The system segments the transportation function by introducing alternative mobile objects as separate entities that can serve users independently. Instead of relying on a single vehicle for both DR participation and user transportation, the system divides the transportation role among multiple mobile objects, allowing the primary vehicle to fulfill DR obligations while alternatives provide user mobility
2Reliability
If the vehicle remains connected to the electric power facility during the DR period, then demand response participation is maintained, but user mobility and flexibility are restricted
Solution Approach 1:
The system dynamically adjusts transportation arrangements based on DR participation status. During DR periods, the server actively provides alternative mobile object information to maintain user flexibility. The system adapts to changing conditions by querying real-time availability of alternatives and notifying users, ensuring mobility flexibility is preserved throughout the DR period
3Ease of operation
If alternative mobile objects are provided to users during DR periods, then user movement convenience is improved, but system complexity increases due to coordination requirements
Solution Approach 1:
The server implements a self-service mechanism by automatically querying the provider server for alternative mobile object information and notifying users without requiring manual intervention. The system autonomously handles the coordination complexity by establishing automated communication channels with providers and processing notifications, reducing the perceived complexity for users while maintaining robust coordination in the background

AI summary
A server includes a storage device, a communication device, and a processing device. The storage device stores DR location information and DR period information. The communication device is configured to communicate with a provider server that stores a database indicating an available period and a use start location of each of a plurality of managed mobile objects. The processing device is configured to perform a process of inquiring the provider server about whether the managed mobile objects include a target mobile object of which the available period is in the DR period and the use start location is in a vicinity area of the DR location. When the managed mobile objects include the target mobile object, the processing device is configured to perform a notification process of notifying the user of target mobile object information indicating the available period and the use start location of the target mobile object.
