EV Power Balancing Server for Travel-Aware Grid Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management systems struggle to maintain power supply and demand balance on a power network when electrified vehicles not connected to bidirectional charging stations during balancing periods, rendering them ineffective as power balancing resources.
Innovation Solution
A server manages power balancing resources connected to a power network, predicting power supply and demand balance based on user travel schedules and offering suggestions or rewards to encourage vehicle participation in power balancing, including connecting to power equipment or using alternative transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrified vehicles are connected to bidirectional charging stations during power balancing periods, then power supply and demand balance on the power network is improved, but user convenience deteriorates because vehicles cannot be used for travel
Solution Approach 1:
The server predicts power supply and demand balance in advance before the balancing period begins, and proactively notifies users of scheduled power balancing activities. This allows users to plan their travel accordingly, reducing the negative impact on convenience while ensuring power balancing resources are available when needed.
Solution Approach 2:
The system provides feedback to users about power balancing schedules, vehicle connection status, and the impact of their decisions. Users receive notifications about upcoming balancing periods and can make informed choices about whether to keep their vehicles connected or use alternative transportation, creating a feedback loop that balances grid needs with user convenience.
2Ease of operation
If electrified vehicles are not connected to bidirectional charging stations during power balancing periods, then user convenience is maintained, but power supply and demand balance on the power network deteriorates
Solution Approach 1:
The server acts as an intermediary between the power network and electrified vehicles, coordinating power balancing activities. It manages the scheduling and notification process, enabling vehicles to participate in power balancing when convenient for users while still providing sufficient resources to maintain grid balance.
Solution Approach 2:
The system provides multiple functions: it manages power balancing resources, predicts power supply and demand balance, notifies users of scheduling, and provides alternative transportation information. This multi-functional approach addresses both grid reliability needs and user convenience requirements through a single integrated system.
3Productivity
If the server provides suggestions and rewards to users, then vehicle participation in power balancing is improved, but system complexity increases
Solution Approach 1:
The server automatically manages the entire power balancing coordination process, including predicting balance needs, notifying users, tracking vehicle connection status, and providing rewards. This automated self-service approach increases participation by reducing the effort required from users while the server handles the complexity of coordination and reward management.
Data Source
AI summary
A server manages power balancing resources electrically connected to a power network. The server includes a processor. In response to receipt of input of a travel schedule including a date and time of travel, a departure point, and a destination point from a user of the vehicle, the processor predicts a power supply and demand balance on the power network for the date and time of travel, based on power supply and demand performance information of the power network. In response to prediction that the power supply and demand balance is going to be adjusted on the date and time of travel, the processor provides the user suggestion to keep the vehicle connected to the power equipment on the date and time of travel and a reward for the vehicle responding to a request to adjust the power supply and demand balance.
