Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing demand response systems are limited in their ability to actively manage and reduce power consumption in smaller households and buildings, as they rely on manual control by managers and are not adaptable to changing consumer behaviors or environments.

Innovation Solution

A demand response method and system that determines device priorities using user preference profiles and outdoor temperature data, generates participation profiles, and adjusts priorities based on successful or unsuccessful participation in energy-saving campaigns, ensuring that devices participate in demand response sequences until a target energy savings is achieved.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If demand response management is performed manually by managers in factories or buildings, then power consumption reduction can be achieved, but the system is not adaptable to changing consumer behaviors or environments and is limited to large-scale facilities

Engineering Contradiction:

Improveadaptability to changing consumer behaviorsVSAvoidmanual control by managers

Core Design Contradiction:

Adaptability or versatilityVSExtent of automation

Solution Approach 1:

The system enables devices to automatically participate in demand response programs without manual intervention. The demand response management server autonomously determines participation profiles for multiple devices, adjusts their operation according to participation profiles, and modifies priorities based on participation success, making the system self-managing and adaptive to changing conditions

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system dynamically adjusts device priorities and participation profiles based on real-time feedback from demand response participation outcomes. The server continuously modifies the operation of devices according to changing consumer behaviors and environmental conditions, making the system flexible and adaptive rather than static

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If automated demand response control is implemented, then adaptability to changing systems or conditions is improved, but device complexity and system infrastructure requirements increase

Engineering Contradiction:

Improveadaptability to changing systems or conditionsVSAvoidsystem infrastructure requirements

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The demand response management server performs multiple functions including determining participation profiles for multiple devices, adjusting device operation according to these profiles, monitoring participation success, and dynamically modifying device priorities. This multi-functional approach consolidates complex operations into a single management system, reducing overall system complexity while maintaining high adaptability

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If multiple devices are controlled to participate in demand response, then power consumption reduction effectiveness increases, but the complexity of managing device priorities and participation profiles increases

Engineering Contradiction:

Improvepower consumption reduction effectivenessVSAvoidcomplexity of managing device priorities

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system segments the demand response management into distinct functional components: determining participation profiles for individual devices, adjusting specific device operations according to their profiles, monitoring participation success for each device, and modifying priorities based on outcomes. This segmentation allows effective management of multiple devices while maintaining organizational simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements a feedback loop where the demand response management server monitors the success or failure of device participation in demand response programs and uses this information to dynamically adjust device priorities and participation profiles. This feedback mechanism optimizes power consumption reduction effectiveness while automating the complex task of managing multiple devices

Inventive Principle:

Principle #23Feedback

AI summary

A demand response method, a demand response system, and a recording medium are provided. The response control method includes: determining priorities of devices to be controlled to participate in a demand response; generating respective participation profiles for the devices based on the determined priorities; and changing the priorities of the devices included in the participation profiles, based on whether participation in the demand response according to the generated participation profiles succeeds. Therefore, the user easily participates in the demand response, and thus energy can be saved.
