Dispatching Mobile Energy Resources for Grid Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for responding to electric power grid conditions, such as shortages or instabilities, lack an efficient mechanism to dispatch mobile energy resources like electric vehicles to specific connection sites based on their proximity and dispatch capacity, leading to suboptimal power responses.
Innovation Solution
A system that identifies suitable mobile energy resources, determines their proximity and dispatch capacity, and ranks them for dispatch to connection sites, ensuring that the combined capacity meets the desired power response magnitude, with incentives for compliance and penalties for non-compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile energy resources are dispatched without proximity-based ranking, then dispatch capacity may be sufficient, but response time and efficiency deteriorate due to suboptimal resource selection
Solution Approach 1:
The system pre-establishes a database of mobile energy resources with their locations, capacities, and connection site associations before grid conditions require dispatch. This preliminary organization enables rapid identification and ranking of suitable resources when dispatch is needed, eliminating the need for real-time searches and improving both efficiency and reducing response time
Solution Approach 2:
The system dynamically changes the selection criteria parameters by ranking resources based on multiple factors including proximity to connection sites, available dispatch capacity, and type of grid condition. This parameter-based ranking system optimizes resource selection to simultaneously achieve high response efficiency and minimal dispatch time
2Productivity
If mobile energy resources are selected without capacity verification, then dispatch speed increases, but power response adequacy deteriorates when combined capacity is insufficient
Solution Approach 1:
The system implements a feedback mechanism where the controller verifies the combined dispatch capacity of selected mobile energy resources against the magnitude of desired power response. If the combined capacity is insufficient, the system adjusts the selection by including additional resources or re-ranking existing selections, ensuring both adequate power response and reasonable dispatch speed through iterative verification
3Productivity
If a centralized dispatch system is implemented, then coordination efficiency improves, but system complexity increases due to additional infrastructure requirements
Solution Approach 1:
The centralized controller is designed to perform multiple functions: identifying mobile energy resources, determining their proximity to connection sites, calculating dispatch capacities, ranking resources based on multiple criteria, and issuing dispatch commands. This multi-functional design consolidates what could be separate complex systems into a single coordinated controller, improving coordination efficiency while managing overall system complexity
