Electric Power Interchange System for Multi-Aggregator Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric power interchange systems, such as those using virtual power plants, face limitations in adjusting supply and demand balance, particularly when power has already been interchanged within a single group of consumers, and do not effectively coordinate power exchange between different resource aggregators.
Innovation Solution
An electric power interchange method and system that utilize a mobile body with a storage battery, managed by multiple aggregators, which obtain and share power supply and demand information across different consumer groups to create and transmit moving plans for efficient power interchange between consumers with deficits or surpluses, optimizing power distribution across multiple groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electric power interchange is limited within a single aggregator group, then system complexity is reduced, but the ability to adjust supply and demand balance is insufficient
Solution Approach 1:
The system segments the power interchange market into multiple aggregator groups, each managing its own consumers independently. This segmentation allows localized optimization while enabling broader coordination through inter-aggregator transactions, resolving the contradiction between simplified internal operations and enhanced overall adaptability.
Solution Approach 2:
Multiple aggregator groups are merged into a coordinated network where they can exchange power and information. This merging enables the system to achieve both reduced complexity within individual aggregators and improved supply-demand balance across the entire network through collaborative optimization.
2Adaptability or versatility
If multiple aggregators coordinate power exchange, then supply and demand balance improves, but device complexity increases
Solution Approach 1:
A centralized coordination mechanism acts as an intermediary between multiple aggregators, managing the complexity of inter-aggregator power exchanges. This intermediary handles matching, pricing, and scheduling functions, allowing aggregators to focus on local optimization while the coordinator manages overall system complexity.
Solution Approach 2:
The coordination system employs dynamic algorithms that adapt to changing supply and demand conditions in real-time. This dynamic approach allows the system to handle complexity efficiently by adjusting coordination intensity and methods based on current market conditions, consumer needs, and resource availability.
3Loss of energy
If mobile body transports power across regions, then energy efficiency improves, but loss of time in power transmission occurs
Solution Approach 1:
The system performs preliminary matching and scheduling of power transactions between aggregators before actual power transfer. By pre-coordinating exchange plans, the system minimizes idle time and ensures that mobile bodies are ready for immediate power transport when needed, reducing overall transmission time while maintaining energy efficiency.
Solution Approach 2:
Mobile bodies are designed with multi-functionality, serving both as power storage units and as transport vehicles. This universal design allows them to efficiently combine power accumulation, transfer, and distribution functions, optimizing the trade-off between energy efficiency and transmission time across different operational scenarios.
