EV Operation Management Equipment for Dynamic Reserve Dispatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in fully utilizing the charge/discharge power potential of electric vehicles (EVs) for power system operating reserves without compromising their operational value for transportation services, especially when EVs are not connected to charging/discharging facilities or have low battery levels.
Innovation Solution
The EV operation management equipment creates an operation plan that optimizes the use of EVs by determining whether to use them for transportation or power system operating reserve services based on real-time data, including EV location, battery status, and facility capacity, using a dispatch table and service management units to maximize operational value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If EVs are utilized for power system operating reserve when connected to charging/discharging facilities, then the operating reserve supply is improved, but the operational value of EVs decreases when battery remaining charge is low
Solution Approach 1:
The system dynamically changes the operational parameters of EVs based on real-time conditions. When an EV is connected to charging/discharging facilities and has sufficient battery charge, it transitions to providing operating reserve service. When battery charge drops below a threshold, the system automatically transitions the EV back to transportation service, thus adapting the operational state to current parameters and resolving the contradiction between reserve supply and operational value
Solution Approach 2:
The invention implements a dynamic dispatch mechanism that continuously adjusts EV utilization based on changing conditions including battery state of charge, connection status to charging facilities, and power system needs. This dynamic approach allows the system to optimize operating reserve supply while preventing degradation of EV operational value by switching modes based on real-time status
2Duration of action of moving object
If EVs are utilized for transportation service, then the operational value is improved, but the charge/discharge power potential cannot be utilized for operating reserve
Solution Approach 1:
The system enables EVs to perform multiple functions - both transportation service and power system operating reserve supply - based on real-time conditions. The dual-functionality mechanism allows the same EV fleet to serve transportation needs during low battery states and transition to energy storage/ discharge operations when connected to facilities and having sufficient charge, thus maximizing the utility of charge/discharge power potential without permanently sacrificing transportation operational value
3Quantity of substance
If the number of EVs connected to charging/discharging facilities is increased for operating reserve, then the operating reserve amount is improved, but the availability of EVs for transportation service decreases
Solution Approach 1:
The system implements partial utilization of EVs for operating reserve - only those EVs that are connected to charging/discharging facilities and have sufficient battery charge are deployed for reserve service, while the remainder continue transportation operations. This partial action approach ensures that operating reserve needs are met to the extent possible without excessively reducing the fleet's transportation availability
Solution Approach 2:
The dynamic dispatch system continuously monitors and adjusts the number of EVs allocated to operating reserve based on real-time conditions including power system needs, EV battery states, and transportation service requirements. This dynamic balancing allows the system to optimize the trade-off between reserve amount and transportation availability rather than using a fixed allocation
