Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Demand Response (DR) signals for electric vehicles (EVs) lack precision in identifying EVs' locations, leading to incorrect requests and potential inconvenience to users, especially as the number of EVs and public charging facilities increases, causing inefficiencies in grid load management.
Innovation Solution
A computer-implemented method and system using a tracking server connected via a wireless network to identify EVs' locations and transmit targeted charge interruption signals based on real-time, historical, and predictive electricity models, ensuring accurate DR signal delivery and user consent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If Demand Response signals are sent to all EVs without location verification, then grid load management is simplified, but incorrect EVs may be targeted causing user inconvenience and reducing system reliability
Solution Approach 1:
A tracking server is introduced as an intermediary between the utility and EVs. The tracking server receives DR signals from the utility, verifies EV locations against the target sector, and selectively forwards signals only to EVs currently charging in the correct sector. This mediator resolves the contradiction by adding location verification (improving reliability) without requiring complex changes to utility systems (maintaining manageable complexity).
Solution Approach 2:
The system performs preliminary location verification before sending DR signals. The tracking server continuously monitors EV locations and pre-validates which EVs are in the target sector before relaying DR signals. This preliminary action ensures that only correctly located EVs receive signals, eliminating the need for post-sending corrections and improving overall system reliability.
2Measurement precision
If EV location tracking and verification systems are implemented, then DR signal accuracy is improved, but system complexity and infrastructure requirements increase
Solution Approach 1:
The tracking server performs multiple functions: it tracks EV locations, verifies sector membership, manages DR signal routing, and maintains communication with both utilities and EVs. By consolidating these functions into a single multi-functional system, the patent reduces overall infrastructure complexity compared to having separate systems for each function, while still achieving high location identification accuracy.
3Adaptability or versatility
If public charging facilities are utilized, then EV charging accessibility is improved, but control over DR signal compliance becomes difficult
Solution Approach 1:
The tracking server establishes two-way communication with EVs at public charging facilities. It sends DR signals to EVs and receives compliance status feedback. This feedback mechanism allows the system to verify whether DR requests are being followed regardless of charging location, maintaining reliability while preserving the versatility of public charging access.
