Microgrid Energy Negotiation for Priority Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microgrid systems lack a centralized energy management system to optimize energy distribution based on demand-driven priorities, leading to unfair power distribution and reliance on external energy grids.
Innovation Solution
A centralized energy negotiation resolution system (ENNRS) that manages energy distribution within a microgrid by prioritizing energy requests from consuming components and resolving conflicts based on predefined lists, using methods like FIFO, LIFO, and game theory to ensure efficient energy allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a microgrid system operates without a centralized energy management system, then the system structure remains simple and decentralized, but energy distribution becomes unfair and the system relies on external energy grids
Solution Approach 1:
The patent introduces a centralized energy negotiation resolution system (ENNRS) as an intermediary between energy consuming components and energy production units. This mediator receives priority lists from consuming components, resolves conflicts using algorithms like FIFO, LIFO, or game theory, and determines optimal energy distribution, thereby ensuring fair energy allocation without requiring complex infrastructure changes
2Adaptability or versatility
If energy consuming components request energy from multiple production units, then energy supply flexibility increases, but priority conflicts between components increase
Solution Approach 1:
The system implements feedback mechanisms where energy consuming components submit priority lists indicating their preferred production units, the ENNRS resolves conflicts based on these priorities and system state, and informs components of the resolved energy source assignments. This closed-loop feedback enables flexible multi-unit energy requests while maintaining orderly conflict resolution through centralized coordination
3Productivity
If the microgrid maximizes internal energy consumption, then reliance on external grids decreases, but energy allocation conflicts between components increase
Solution Approach 1:
The patent changes the parameter of energy allocation from equal or first-come-first-served distribution to priority-based allocation. Each consuming component provides a priority list parameter that ranks preferred production units, and the ENNRS uses these parameters along with resolution algorithms (FIFO, LIFO, game theory) to maximize internal energy consumption while systematically resolving allocation conflicts

AI summary
The embodiments herein relate to methods and apparatus for controlling a microgrid network (100). The microgrid (100) comprises an energy negotiation resolution system (110) configured to receive from each energy consuming component (120) of the microgrid (100) a list with information on power supply/production units; determine whether there is a conflict in priorities between received lists with regards to the listed energy production units (130, 120, 140), based on requests received from each energy consuming components (120); resolve the conflict when there is a conflict in priorities; and inform each energy consuming component (120) involved in the conflict of the energy production unit (130, 120, 140) to use as energy source. The embodiments also relate to the energy consuming component (120) and a method therein.
