Vehicle-to-Grid Power Control Across Regional Grid Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of vehicle-to-grid (V2G) technology is restricted due to the need for vehicles to comply with varying grid codes across different regions, which can lead to increased costs and reduced production efficiency as vehicle specifications must be diversified to meet regional requirements.
Innovation Solution
A method and system that identifies the current location of a vehicle and adjusts power supply to the grid according to the specific grid code of the region, using a location identification unit and a power control unit to manage parameters such as voltage, frequency, and reactive power control, ensuring compliance with regional grid codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle specifications are diversified to meet regional grid code requirements, then compliance with regional grid codes is improved, but production efficiency and cost are deteriorated
Solution Approach 1:
The power control unit dynamically adjusts power supply parameters (voltage, frequency, reactive power) based on the detected regional grid code, allowing a single vehicle specification to adapt to multiple regional requirements without physical modification or diversification of vehicle components
Solution Approach 2:
The system changes operational parameters (power supply characteristics) according to the detected region's grid code requirements, enabling compliance with different regional standards through software-based parameter adjustment rather than hardware diversification
2Adaptability or versatility
If vehicle specifications are diversified to meet regional grid code requirements, then compliance with regional grid codes is improved, but cost is increased
Solution Approach 1:
The power control unit is designed with universal functionality to support multiple grid codes through software configuration rather than hardware variation, allowing a single vehicle model to serve multiple regional markets without increasing manufacturing complexity or cost
Solution Approach 2:
Instead of creating different hardware specifications for each region, the system uses software-based parameter sets that replicate the required grid code compliance characteristics, eliminating the need for costly physical diversification
3Productivity
If fixed grid code settings are used in vehicles, then production efficiency is improved, but V2G operation is restricted when moving between regions
Solution Approach 1:
The system transitions from static, fixed grid code settings to dynamic, region-adaptive power control by detecting the current region and automatically adjusting power supply parameters to match the local grid code requirements
Solution Approach 2:
The region detection unit provides feedback about the current geographic location to the power control unit, which then adjusts power supply parameters accordingly, creating a closed-loop system that maintains V2G compliance across different regions

AI summary
A method for controlling power of a vehicle includes identifying the current location of a vehicle, determining whether to enter the a grid code-changing region based on the identified current location of the vehicle, and controlling the power supplied from the vehicle to the power grid according to a parameter corresponding to the grid code of the region when entering to the grid code-changing region is determined.
