Priority-Based Power Allocation for Industrial Supply-Demand Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply-demand control devices do not adequately prioritize electric power demands, leading to inefficient allocation and potential neglect of critical power requirements in industrial settings.
Innovation Solution
A supply-demand control device that assigns priority ranks to various power or energy demands and sets allowable limits for each rank, ensuring that power or energy is allocated based on priority, with trimming of upper and lower limits to prevent over-allocation to lower priority demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power or energy is allocated based on operational stability alone, then supply-demand balance is ensured, but appropriate electric power supply based on priorities is not performed
Solution Approach 1:
The patent segments power demands into multiple priority ranks (first priority, second priority, etc.) and allocates power accordingly. This segmentation allows the system to differentiate between critical and non-critical loads, ensuring that high-priority demands receive power first while maintaining overall supply-demand balance.
Solution Approach 2:
The patent applies local quality by setting different allowable limits for different priority ranks. Each priority rank has its own specific allowable limit (first allowable limit, second allowable limit, etc.), allowing tailored power allocation strategies for different types of demands based on their priority level.
2Ease of operation
If allowable limits are set for each priority rank, then appropriate power allocation based on priority is achieved, but device complexity increases
Solution Approach 1:
The patent implements dynamic power allocation by continuously monitoring total power demand and adjusting the allocation among priority ranks in real-time. When total demand exceeds supply capacity, the system dynamically reduces power to lower-priority ranks while maintaining power to high-priority ranks, creating a flexible adaptive control system.
Solution Approach 2:
The patent changes the parameter of allowable limits based on priority ranks and system conditions. The allowable limits (first allowable limit, second allowable limit, etc.) are adjustable parameters that can be modified based on power supply capacity and demand patterns, enabling flexible control without complex reconfiguration.
3Reliability
If power is allocated to higher priority demands first, then critical power requirements are met, but power allocation to lower priority demands is reduced
Solution Approach 1:
The patent performs preliminary action by pre-establishing priority ranks and allowable limits for different power demands before power allocation decisions are needed. This preliminary classification and limit-setting enables rapid response during power shortages without requiring complex real-time analysis of each demand's importance.
Solution Approach 2:
The patent applies partial action by allocating power selectively to different priority ranks based on available capacity. When power supply is sufficient, all demands up to their allowable limits are satisfied. When power is limited, the system partially satisfies lower-priority demands only after meeting high-priority demands, ensuring critical needs are always met first.

AI summary
A supply-demand control device is configured to: set, for each priority rank defined in advance, an allowable limit within a range of a value set for a higher priority rank than the each priority rank, the allowable limit indicating an upper limit of the power or the energy allowed to be supplied in response to a demand of the each priority rank while the power or the energy supplied in response to a demand of the higher priority rank is secured; detect the demand for the power or the energy, which occurs in the industrial product; and allocate, in order of the priority rank, the power or the energy supplied from a predetermined supply source in response to the detected demand, such that the supplied power or energy is equal to or lower than the upper limit indicated by the allowable limit set for the each priority rank.
