Building Power Management for Demand Response Feasibility Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power management systems lack the ability to effectively determine the ease or difficulty of achieving power saving targets for demand response requests, leading to inefficient balancing of power supply and demand.
Innovation Solution
A power management device that acquires and stores consumption data, assesses requests based on historical information, weather, and power generation capabilities, and notifies customers of the feasibility of meeting demand response targets, allowing them to make informed decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If demand response requests are issued to power customers without providing feasibility information, then power supply and demand balancing can be initiated, but customers cannot make informed decisions about accepting or rejecting requests
Solution Approach 1:
The power management device performs preliminary analysis of power consumption history and demand response requirements before issuing requests to customers. It calculates feasibility indicators in advance, so that when a demand response request is made, the customer receives pre-computed information about whether the target is achievable, enabling informed decision-making without adding complex real-time analysis requirements
Solution Approach 2:
The system pre-processes power consumption data and establishes feasibility assessment mechanisms before demand response events occur. By having the analytical framework and historical data ready in advance, the system cushions against the complexity that would otherwise arise during actual demand response execution, providing smooth feasibility information to customers
2Measurement precision
If power management requires detailed historical analysis and real-time assessment, then accurate feasibility determination is achieved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary aggregation and analysis of power consumption history data, storing processed information that can be quickly referenced during demand response events. This pre-computation maintains high accuracy in feasibility determination while reducing the processing time required when actual requests are evaluated
Solution Approach 2:
The power management device focuses analysis on the most relevant historical periods and key consumption patterns rather than processing all available data equally. By concentrating computational effort on the most significant factors affecting feasibility, the system achieves accurate assessments without unnecessary processing overhead
3Adaptability or versatility
If demand response targets are set without considering historical power consumption patterns, then flexible power management is maintained, but targets become unrealistic and difficult to achieve
Solution Approach 1:
The system performs preliminary assessment of demand response targets by comparing requested reductions against historical power consumption patterns. Before confirming a target with the customer, the system evaluates whether the target is realistic based on past behavior, ensuring that flexible power management goals are grounded in actual consumption capabilities
Solution Approach 2:
The power management device provides feedback to customers about the feasibility of proposed demand response targets based on historical analysis. This feedback loop allows the system to maintain flexibility in setting targets while ensuring they remain achievable, as customers receive information about whether their historical patterns support the requested reductions

AI summary
This power management device acquires power consumption information in a building of a power customer, and stores history information in which the acquired power consumption information and time information indicating a time frame in which power has been consumed in the building are associated with each other. When having received a request based on power supply and demand, the power management device determines ease or difficulty in management of power consumption according to the request, on the basis of the stored history information, and power-management-required time frame information indicating a time frame for which power management according to the request is required, and notifies the power customer of a determination result. Then the power management device receives acceptance or rejection of the request, and transmits response information corresponding to a received content, to a request source.
