EV Power Allocation for Blackout Grid Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively utilize battery energies of scattered electric vehicles and balance demand and supply of electric power, especially during emergencies or disasters.
Innovation Solution
A power information processing apparatus and method that obtains and compares demand and supply data to allocate and guide electric vehicles to discharge power to the power system network, utilizing a network of servers to determine allocation and guide electric vehicles to charging/discharging units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electric vehicles are scattered in various places and not in operation, then the system complexity is reduced, but the ability to balance demand and supply of electric power during emergencies deteriorates
Solution Approach 1:
The patent introduces a server as an intermediary that collects information from multiple electric vehicles and charging/discharging apparatuses, and performs centralized allocation calculations. This mediator coordinates the scattered EVs without requiring them to directly communicate with each other, thus maintaining low system complexity while achieving reliable power balancing during emergencies through centralized optimization.
2Reliability
If a centralized system allocates electric vehicles to power system networks, then the ability to balance demand and supply improves, but the device complexity increases
Solution Approach 1:
The server acts as a centralized intermediary that handles all allocation calculations and decision-making. It collects information from scattered EVs and charging apparatuses, performs the optimization calculations, and sends guidance information back. This concentrates the complexity in a single centralized unit rather than distributing it across multiple devices, achieving reliable power balancing while keeping individual device complexity low.
3Reliability
If electric vehicles are guided to charging/discharging units during blackouts, then the power supply reliability improves, but the time required for allocation and guidance increases
Solution Approach 1:
The server collects information from electric vehicles and charging/discharging apparatuses in advance, before emergencies occur. By having this information pre-collected and organized, the server can perform rapid allocation calculations when a blackout occurs, reducing the response time while ensuring reliable power supply through pre-established communication channels and data structures.
