Dynamic Parking Fee Control for Vehicle-to-Grid Demand Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for converting vehicle battery power into monetary compensation for parking fees lack efficiency in guiding vehicles to connect with the power network based on demand, leading to suboptimal power supply and demand balancing.
Innovation Solution
A power transmission and reception system that uses a management server to control usage fees for parking lots based on power demand, guiding vehicles with suitable chargeable or dischargeable amounts to connect with the power network, facilitating power supply and demand balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed parking fee system is used, then the system is simple to operate, but it cannot effectively guide vehicles to connect with the power network based on demand
Solution Approach 1:
The parking fee system transitions from a fixed fee structure to a dynamic fee structure that adjusts based on real-time power demand. The management server continuously monitors power demand and automatically modifies parking fees to incentivize vehicle connection to the power network when demand is high, thereby achieving adaptability without requiring complex manual intervention
Solution Approach 2:
The system implements a feedback loop where the management server monitors power demand status and uses this information to adjust parking fees accordingly. This feedback mechanism enables the system to adapt to changing power demand conditions automatically, guiding vehicles to connect when needed while maintaining relative system simplicity through automated decision-making
2Reliability
If dynamic fee adjustment based on power demand is implemented, then power supply and demand balancing is improved, but the system complexity increases
Solution Approach 1:
The management server performs multiple functions: it manages parking reservations, calculates parking fees, monitors power demand status, and communicates with both user terminals and the power network. By consolidating these diverse functions into a single multi-functional system, the patent achieves improved power supply reliability without proportionally increasing overall system complexity
Solution Approach 2:
The management server acts as an intermediary between the power network and user terminals, translating power demand status into parking fee adjustments and conveying user reservations to the power network. This intermediary role simplifies the overall system architecture by centralizing communication and control, thereby improving power supply stability without requiring complex direct connections between all components
3Productivity
If vehicles are guided to connect based on chargeable/dischargeable amounts, then power demand response efficiency is improved, but information processing complexity increases
Solution Approach 1:
The system utilizes changes in battery state parameters (chargeable and dischargeable amounts) as the primary mechanism for guiding vehicle connection. By monitoring these parameter changes and translating them into fee adjustments, the system achieves efficient power demand response without requiring complex control algorithms, relying instead on straightforward parameter-based decision-making
