Power Transaction Matching Using Communication Latency Scores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In power trading markets, real-time power transactions between facilities connected to low-voltage power grids can disrupt the balance between supply and demand, as the timing of reverse power flow and power flow from the grid may not align, leading to potential imbalances if not managed effectively.
Innovation Solution
A power management system and method that includes a controller and communication unit to evaluate and match power purchasing and selling facilities based on communication time, calculating a score that reflects the evaluation of facilities connected via a communication path, ensuring appropriate matching and balancing supply and demand by adjusting the timing of power transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If real-time power transactions are enabled between facilities connected to low-voltage power grids, then power trading flexibility and responsiveness are improved, but supply-demand balance stability deteriorates due to timing misalignment between reverse power flow and grid power flow
Solution Approach 1:
The power management server continuously monitors communication times between facilities and uses this feedback to dynamically adjust matching decisions. By measuring the actual communication latency and using it as a criterion for selecting power trading partners, the system adapts to real-time conditions while maintaining supply-demand balance through informed matching rather than arbitrary pairing.
2Device complexity
If facilities are matched without considering communication time, then device complexity is reduced, but power transaction reliability deteriorates due to timing mismatches in real-time transactions
Solution Approach 1:
The system introduces communication time as a critical parameter in the facility matching process. By evaluating and comparing communication times between different facility pairs, the system transforms the matching criterion from a simple availability check to a time-optimized selection process, thereby improving transaction reliability without requiring complex additional hardware.
3Loss of time
If communication time is used as a matching criterion, then power transaction timing accuracy is improved, but information processing requirements increase
Solution Approach 1:
The system implements a practical compromise by using communication time as one of several matching criteria rather than the sole determinant. This partial application of time-based matching reduces the information processing burden while still capturing the essential timing benefits, avoiding the excessive data collection and analysis that would be required for complete real-time optimization.

AI summary
A power management system for providing a mechanism of power transaction between two or more facilities connected to a power grid, the system includes a controller configured to extract, from the two or more facilities, a power selling facility other than a power purchasing facility by an input from a user terminal corresponding to the power purchasing facility which is one of the two or more facilities, and calculate a score indicating a value of the power transaction based on a communication time in a communication path between the power selling facility and the power purchasing facility, and a notification unit configured to notify the user terminal of the score.
