Facility Demand Adjustment Control with Selective Device Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional demand adjustment systems struggle to flexibly control devices to meet adjustment amounts within requested ranges, leading to potential discomfort for users and operational disruptions in facilities.
Innovation Solution
A demand adjustment control system that includes an obtainer, determiner, and controller to selectively manage first and second devices, where first devices maintain their mode and second devices can change, ensuring adjustment amounts fall within target ranges without repeated mode changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If demand adjustment control is applied to all devices to meet target adjustment amounts, then power demand adjustment effectiveness is improved, but facility operation stability deteriorates due to repeated mode changes
Solution Approach 1:
The device group is segmented into first devices (fixed mode) and second devices (changeable mode). This segmentation allows the system to apply demand adjustment control selectively - second devices can change modes to contribute to adjustment amounts while first devices maintain stable operation, thus resolving the contradiction between adjustment effectiveness and operational stability.
2Manufacturing precision
If device modes are frequently changed to achieve adjustment amounts within requested ranges, then demand adjustment precision is improved, but user comfort deteriorates due to operational disruptions
Solution Approach 1:
Different quality characteristics are assigned to different device groups: second devices are permitted to have changing modes (local flexibility) to achieve precise adjustment amounts, while first devices maintain fixed modes (local stability) to avoid disrupting user comfort. This local differentiation resolves the contradiction between adjustment precision and user comfort.

AI summary
A demand adjustment control system includes an obtainer, a determiner, and a controller. The obtainer obtains a target adjustment amount according to a temporary demand adjustment request. The determiner determines one or more target devices each of which is to be a target of demand adjustment control from a device group in a facility, based on the target adjustment amount obtained by the obtainer. The controller executes the demand adjustment control on the one or more target devices to cause an adjustment amount achieved by the one or more target devices to fall within a range of the target adjustment amount during a period in which demand adjustment is being requested. The device group includes one or more first devices of which demand adjustment control mode is not changed during the period and one or more second devices of which demand adjustment control mode can be changed during the period.
