EV Power Dispatch Filtering for Cyberattack-Resilient Supply Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing risk of cyberattacks on electric vehicles (EVs) compromises their data integrity, rendering them unreliable as power sources, particularly in systems where EVs are used to supply power to facilities.
Innovation Solution
A power supply demand control device that collects EV information and power facility information, identifies suspicious EVs through alert data, and excludes them from power dispatch calculations to mitigate the impact of cyberattacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If EVs are used as power sources in a distributed power system, then the system's power supply capability is improved, but the system becomes vulnerable to cyberattacks that compromise data integrity
Solution Approach 1:
The system performs preliminary detection of cyberattacks by monitoring alert information from EVs before they can compromise the distributed power system. The detection unit identifies suspicious EVs based on alert data, and the exclusion unit removes them from power supply calculations in advance, preventing potential data integrity issues from affecting system reliability
Solution Approach 2:
The control device acts as an intermediary between the distributed EV power sources and the central power management system. It receives alert information from EVs, processes this information to detect cyberattacks, and makes decisions about which EVs to include or exclude from power supply operations, thereby protecting the overall system from compromised data
2Productivity
If all collected EV information is used for power dispatch planning, then the power distribution efficiency is improved, but the system reliability deteriorates due to potential cyberattack-compromised data
Solution Approach 1:
The exclusion unit extracts and removes EVs with compromised data integrity from the set of available power sources. By identifying EVs that have received cyberattacks through alert information analysis, the system separates problematic EVs from the reliable ones, ensuring that only trustworthy EV data is used in dispatch planning while maintaining efficient power distribution
Solution Approach 2:
The system implements a feedback mechanism where alert information from EVs is continuously monitored and analyzed. When cyberattacks are detected, this feedback triggers the exclusion of affected EVs from power dispatch planning, creating a closed-loop system that adapts to security threats while maintaining optimal power distribution
