Dynamic Incentive Ranking for EV Power Grid Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply/demand adjustment methods fail to effectively secure users of electric vehicles for charge and discharge when power supply/demand balance is significantly lost at power transmission/distribution facilities, leading to inefficiencies in power exchange.
Innovation Solution
A power system apparatus and method that includes a power supply/demand information acquisition unit, calculators for urgency and redundancy degrees, a communication unit for notifications, a charge/discharge management unit, and an incentive management unit to calculate and impart rank points and incentives to users based on their participation in power supply/demand adjustments, prioritizing users for charge/discharge requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general incentive schemes are used for power supply/demand adjustment, then user participation is encouraged, but users are not reliably secured at critical times when power exchange is most needed
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting incentive levels based on the urgency degree of power supply/demand situations. The incentive management device changes the incentive parameters (reward amounts) according to the calculated urgency degree, transforming a static incentive system into a dynamic one that adapts to critical conditions, thereby reliably securing user participation when most needed.
Solution Approach 2:
The patent implements feedback by continuously monitoring power supply/demand balance information, calculating urgency degrees, and adjusting incentives accordingly. The system receives feedback on the current power balance state, processes this information through urgency calculation, and provides adjusted incentive feedback to users, creating a closed-loop control system that ensures reliable participation at critical times.
2Productivity
If simple incentive schemes are used, then system operation is simple, but power supply/demand balance cannot be effectively restored at critical moments
Solution Approach 1:
The patent applies preliminary action by pre-calculating and preparing incentive levels based on predicted power supply/demand situations. The urgency calculation device performs preliminary assessments of potential critical conditions and prepares appropriate incentive responses in advance, enabling rapid restoration of power balance when critical situations actually occur, without requiring complex real-time decision-making during emergencies.
3Adaptability or versatility
If uniform incentives are provided to all users, then implementation is straightforward, but users with different urgency levels are not differentiated
Solution Approach 1:
The patent applies local quality by providing differentiated incentive levels tailored to specific local conditions (individual user situations and local power supply/demand conditions). The incentive management device calculates distinct urgency degrees and incentive amounts for different users based on their specific contexts, ensuring that each user receives appropriately adapted incentives rather than uniform treatment, thereby enhancing overall system adaptability.
