Power Demand Control System Using Feedback for Grid Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power control systems face challenges in accurately managing power demand due to uncertainty in consumer compliance with demand-response measures, leading to instability in power supply and demand balance.
Innovation Solution
A power control system that acquires and adjusts power demand information from consumers using predetermined apparatuses, such as air conditioners and storage cells, to compensate for differences between actual and target demand amounts, ensuring high-accuracy alignment with target power demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If demand-response measures are implemented to adjust power demand, then power supply and demand balance is improved, but accuracy of demand management deteriorates due to uncertainty in consumer compliance
Solution Approach 1:
The patent implements a feedback mechanism where the management device receives information about actual power demand from consumers after issuing demand adjustments. This feedback loop allows the system to monitor whether consumers actually controlled their electrical equipment according to the issued demands, enabling accurate measurement of demand management effectiveness and allowing for corrective actions if compliance is insufficient.
2Reliability
If thermal generators are used to adjust output and compensate for renewable power fluctuation, then power supply stability is improved, but system complexity and cost increase
Solution Approach 1:
The patent enables the consumer side to self-manage power demand through automated control of electrical equipment based on issued demands. Instead of requiring complex thermal generator adjustments on the supply side, the system allows consumers to automatically adjust their own power consumption patterns, thereby maintaining power supply stability through distributed self-service rather than centralized complex control.
3Adaptability or versatility
If consumer-controlled demand adjustment is implemented, then flexibility in demand management is improved, but control precision deteriorates due to lack of monitoring
Solution Approach 1:
The system maintains flexibility by allowing consumers to control their own electrical equipment while simultaneously implementing monitoring through the feedback mechanism. The management device receives information about actual power demand and can verify whether consumers adhered to the issued demands, thus preserving both consumer autonomy and control precision through transparent monitoring.

AI summary
A power control system includes an acquisition unit that acquires information indicating the amount of power demand that is used by a consumer according to predetermined information that prompts adjustment of the power demand, and a control unit that controls a predetermined apparatus in accordance with a target demand amount and the information indicating the power demand amount.
