Power Resource Selection for Variable Grid Adjustment Demand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Management devices struggle to effectively utilize small capacity resources for power adjustments in power grids due to their inability to follow large increases in power adjustment amounts, while relying solely on large capacity resources can lead to insufficient power adjustment capabilities.
Innovation Solution
A management device that classifies power resources into small and large capacity resources and selectively chooses the appropriate resource based on the power adjustment request, prioritizing small capacity resources for small adjustments and large capacity resources for large adjustments, ensuring effective power grid balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If small capacity resources are selected as adjustment resources, then the number of available adjustment resources increases, but the ability to follow large increases in power adjustment amount deteriorates
Solution Approach 1:
The patent implements dynamic resource selection by classifying power resources into first resources (small capacity) and second resources (large capacity), and dynamically switching between them based on the power adjustment amount. When the power adjustment amount is within a threshold, first resources are selected; when it exceeds the threshold, second resources are selected. This dynamic adaptation resolves the contradiction between maximizing resource quantity and maintaining adaptability to large power adjustment increases.
2Adaptability or versatility
If only large capacity resources are selected as adjustment resources, then the ability to follow power adjustment amount increase improves, but the number of available adjustment resources deteriorates
Solution Approach 1:
The system dynamically adjusts resource selection based on the magnitude of power adjustment requests. By setting a threshold value and comparing the power adjustment amount against it, the system flexibly switches between using small capacity resources (first resources) for minor adjustments and large capacity resources (second resources) for major adjustments. This dynamic approach ensures both sufficient resource quantity and adequate adaptability to varying power adjustment demands.
3Productivity
If small capacity resources are used for power adjustment, then resource utilization efficiency improves, but power adjustment reliability deteriorates when adjustment amount increases significantly
Solution Approach 1:
The patent changes the selection parameter from fixed (always using small or always using large capacity resources) to variable (based on power adjustment amount threshold). By introducing a threshold value and dynamically adjusting resource selection based on whether the power adjustment amount exceeds this threshold, the system maintains high resource utilization efficiency for normal operations while ensuring reliability when significant power adjustments are required.

AI summary
A server executes: a classification process of classifying each of power resources into a first resource and a second resource with a capacity of the power storage device larger than the capacity of the power storage device of the first resource; and a resource selection process of selecting, from among the power resources, an adjustment resource of which participation in the power adjustment is requested. The resource selection process includes a first selection process of preferentially selecting the first resource as the adjustment resource over the second resource when a power adjustment request is a first request, and a second selection process of preferentially selecting the second resource as the adjustment resource over the first resource when the power adjustment request is a second request. A power adjustment amount of the second request is larger than a power adjustment amount of the first request.
