Demand Control Change History for Contract Power Accountability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a target value in demand control changes, such as exceeding contract power, leading to penalties and potential health risks for equipment appliance users, there is a lack of information on the change, making it difficult to determine responsibility and take appropriate measures.
Innovation Solution
An information processing system that includes a storage unit for demand target values and an acquisition unit to store and provide information on changes, including timing, user identity, reason, and device used, enabling the tracking and notification of changes in demand target values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If demand target value is changed to control power consumption, then power consumption is reduced, but information on the change is lost making responsibility determination difficult
Solution Approach 1:
The system performs preliminary action by storing information on the demand target value before any changes occur. The storage unit saves the original target value, and when a change is made, the system records the change history including the old value, new value, timing, and user identity. This preliminary recording ensures that information is preserved before potential loss occurs during the change process.
Solution Approach 2:
The system implements feedback by providing information on demand target value changes to relevant parties. The notification unit sends change information to users and managers, creating a feedback loop that ensures information is not lost but rather circulated back to stakeholders. This allows responsibility determination and appropriate measures to be taken based on the feedback received.
2Reliability
If demand target value is changed to prevent penalties, then contract power compliance is improved, but user health may be compromised by extreme operation control
Solution Approach 1:
The system applies dynamics by allowing the demand target value to be flexible and changeable based on actual conditions. Instead of enforcing a fixed rigid target, the system enables dynamic adjustment of the target value within reasonable limits. The notification unit informs users of changes, allowing them to adapt gradually rather than experiencing extreme abrupt controls that would harm their health.
Solution Approach 2:
The notification unit serves as an intermediary between the system's demand control function and the user. It mediates the impact of target value changes by providing advance notice and information, allowing users to prepare for and adapt to changes smoothly. This intermediary role prevents extreme operation control by enabling gradual user adaptation while still achieving contract power compliance.
3Device complexity
If demand target value change information is not provided, then system operation is simple, but appropriate measures cannot be taken due to unknown responsibility
Solution Approach 1:
The system extracts the information management function from the core demand control operation. By separating the information storage and notification functions into distinct components (storage unit, notification unit), the system maintains simple core operation while adding the necessary information tracking capability. This extraction allows appropriate measures to be taken without significantly complicating the overall system operation.
Solution Approach 2:
The system implements self-service by automatically recording and notifying of demand target value changes without requiring manual intervention. The storage unit automatically saves change information, and the notification unit automatically informs relevant parties. This self-service approach enables appropriate measures to be taken based on automatic information provision while keeping system operation simple and requiring minimal human effort.

AI summary
[Object] To make it possible to, when a target value in demand control is changed, acquire and store information on the target value and provide the information as necessary.[Solution] An information processing system performs setting related to demand control of an equipment appliance, and includes: a storage unit 120 that stores a demand target value in the demand control; and a history information generation unit 160 that acquires information on the demand target value input by a user. The storage unit 120 further stores a change history of the demand target value based on the information on the demand target value acquired by the history information generation unit 160.
