Power Resource Selection for Variable Grid Adjustment Demand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management devices for power resources struggle to effectively utilize small capacity resources for power adjustments, as they often cannot follow large increases in power adjustment amounts, leading to insufficient participation in power grid balance management.
Innovation Solution
A management device that classifies power resources into small and large capacity resources and selectively chooses adjustment resources based on the power adjustment request, prioritizing large capacity resources for large adjustments and small capacity resources for small adjustments, ensuring appropriate utilization and participation in power grid balance management.
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 they cannot follow large increases in power adjustment amount
Solution Approach 1:
The patent implements dynamic resource selection by classifying power resources into first resources (smaller capacity) and second resources (larger capacity), and dynamically selecting which type to prioritize based on the power adjustment amount. When the adjustment amount is small, first resources are preferentially selected; when large, second resources are preferentially selected. This dynamic adaptation resolves the contradiction between quantity and adaptability.
Solution Approach 2:
The patent changes the selection parameter (resource capacity classification) based on the power adjustment amount parameter. By establishing a threshold for the power adjustment amount, the system switches between selecting first resources (smaller capacity) and second resources (larger capacity), allowing small capacity resources to be effectively utilized for small adjustments while ensuring large capacity resources handle large adjustments.
2Adaptability or versatility
If only large capacity resources are selected as adjustment resources, then they can easily follow large increases in power adjustment amount, but the number of available large capacity resources may be insufficient
Solution Approach 1:
The system dynamically adjusts the selection criteria based on the power adjustment amount. Instead of statically selecting only large capacity resources, the system switches between preferentially selecting first resources and second resources based on whether the adjustment amount exceeds a threshold, thereby increasing the available pool of adjustment resources when appropriate.
Solution Approach 2:
The patent changes the selection parameter from fixed (only large capacity) to variable (based on power adjustment amount threshold). This allows the system to utilize first resources for small adjustments and second resources for large adjustments, effectively increasing the total number of available adjustment resources while maintaining the ability to handle large power adjustments.
3Productivity
If small capacity resources are used for power adjustment, then more resources can participate in power grid balance management, but they may not be able to handle large power adjustment amounts
Solution Approach 1:
The patent introduces a threshold parameter for the power adjustment amount that determines which resource type is preferentially selected. When the adjustment amount is below the threshold, first resources (smaller capacity) are selected, increasing participation. When above the threshold, second resources (larger capacity) are selected, ensuring reliability. This parameter-based switching resolves the contradiction between productivity and reliability.
Solution Approach 2:
The system dynamically switches between utilizing first resources and second resources based on the power adjustment amount. This dynamic selection ensures that small capacity resources participate in manageable adjustments (improving productivity) while large capacity resources handle substantial adjustments (maintaining reliability).

AI summary
A server executes: a classification process of classifying each of a plurality 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 second resource as the adjustment resource over the first resource when a power adjustment request is a first request, and a second selection process of preferentially selecting the first resource as the adjustment resource over the second resource when the power adjustment request is a second request. A power adjustment amount of the first request is larger than a power adjustment amount of the second request.
