Power Demand-Supply Control Using Minimum Adjustment Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power control systems face challenges in accurately managing power demand and supply balance due to a time lag between the power supplier's request for adjustment and the customer's response, which can lead to increased burden on customers and inefficiencies in demand-supply alignment.
Innovation Solution
An apparatus that sends requests to adjust power consumption based on supply and demand, utilizing a memory unit to store minimum adjustment times for each request target, a selection unit to choose targets with acceptable adjustment times, and a calculation unit to determine adjustment amounts, thereby optimizing power adjustments across multiple request targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the power supplier requests power adjustment at a time close to the customer's adjustment start time to shorten the time lag, then the accuracy of power demand-supply balance control is improved, but the customer's burden increases and the customer might not perform the adjustment
Solution Approach 1:
The system performs preliminary actions by calculating and storing the minimum adjustment time for each request target in advance. The selection unit uses this pre-calculated information to identify suitable targets before sending adjustment requests, ensuring that requests are sent at optimal times that allow customers sufficient preparation time while maintaining control accuracy.
2Productivity
If the power supplier sends adjustment requests to multiple customers simultaneously to improve overall demand-supply balance control, then the productivity of power balance management is improved, but the complexity of selecting appropriate request targets increases
Solution Approach 1:
The system segments the customer base into individual request targets, each with their own minimum adjustment time characteristics stored in the memory unit. The selection unit processes these segmented targets individually, selecting appropriate ones based on their specific adjustment time requirements, thereby managing complexity through systematic division while maintaining high productivity through parallel processing capabilities.
Solution Approach 2:
Each request target effectively serves itself by having its minimum adjustment time pre-calculated and stored in the memory unit. The selection unit automatically retrieves and uses this information to make selection decisions, reducing the need for complex manual evaluation and enabling efficient automated processing of multiple targets.

AI summary
According to one embodiment, an apparatus sends a request to adjust a power consumption to a plurality of request targets, based on power supply and demand. A minimum adjustment time of each request target is stored. The minimum adjustment time is an interval between a time when a request target receives the request and a time when the request target starts to adjust the power consumption. If an estimation value of the power supply is different from an estimation value of the power demand at a first time to start to adjust, at least one request target is selected from the request targets by using the minimum adjustment time. The at least one request target is acceptable for the request at a second time as a predetermined time prior to the first time. A first adjustment amount to the at least one request target is calculated until the second time.
