Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional decentralized energy resource management technologies are limited in their ability to manage and utilize distributed energy resources effectively across wide areas, especially during emergencies, as they primarily supply energy locally and lack integrated management of diverse resources.
Innovation Solution
A system and method for decentralized energy resource-based active virtual power energy management, which involves real-time monitoring of available energy resources, hierarchical management, and clustering of virtual energy resources to meet customer demand patterns, using a meter data management device, resource aggregator, and virtual energy generation resource management device to select and control decentralized energy resources for efficient energy supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If decentralized energy resources supply energy locally and independently, then energy supply autonomy is improved, but energy resource utilization efficiency deteriorates
Solution Approach 1:
The patent merges multiple decentralized energy resources into a virtual power plant system that operates collectively. The management server aggregates resources from multiple locations, enabling integrated optimization of energy supply while maintaining the decentralized physical structure. This resolves the contradiction by combining resources virtually to improve utilization efficiency without sacrificing local supply autonomy.
Solution Approach 2:
The patent introduces a management server as an intermediary between decentralized energy resources and the power grid. This intermediary coordinates resource allocation, matches supply with demand patterns, and optimizes overall system efficiency while allowing local resources to maintain operational independence. The mediator enables efficient resource utilization without requiring centralized control.
2Area of stationary object
If decentralized energy resources are distributed over a wide area, then energy supply coverage is improved, but resource management complexity deteriorates
Solution Approach 1:
The patent segments the management system into hierarchical layers: a central management server handles high-level coordination and optimization, while local control units manage individual resource operations. This segmentation allows wide-area coverage through distributed resources while reducing management complexity by dividing responsibilities across multiple management levels.
Solution Approach 2:
The management server implements a universal platform that handles multiple functions: resource registration, load profile analysis, real-time monitoring, and optimization across diverse decentralized resources. This multi-functional approach simplifies management complexity by providing a single integrated system that can handle various resource types and operations uniformly.
3Reliability
If conventional decentralized energy resource management is used, then local energy supply is improved, but emergency response capability deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-analyzing customer load profiles and pre-identifying suitable energy resources before emergencies occur. The system stores this analysis results and can rapidly deploy pre-identified resources during emergencies, improving response capability while maintaining local supply reliability through pre-established resource-customer matching.
