Power Demand Supply Control Apparatus Timing Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power demand and supply control systems face challenges in accurately managing the balance between demand and supply due to time lags in power adjustment requests, which can increase the burden on customers and lead to inaccurate control, especially when requests are made too early or too late, and when energy storage devices are insufficient.
Innovation Solution
A power demand and supply control apparatus that requests power adjustments from multiple targets before the execution time, utilizing a target value acquiring unit, information collecting unit, adjustment amount determining unit, and communication unit to create a DR plan, determining adjustment amounts based on registered power amounts and executable times, and transmitting DR signals to manage power adjustments within registered capacities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the power adjustment request is made immediately before the execution time and date, then the time lag is reduced, but the burden on the customer is increased and the customer may not be able to respond due to insufficient energy storage capacity
Solution Approach 1:
The system performs preliminary estimation of power adjustment requirements before the execution time, allowing customers to prepare their energy storage devices in advance. The control apparatus calculates the required adjustment amount based on predicted demand-supply imbalance and notifies customers beforehand, enabling them to charge or discharge storage devices at convenient times rather than facing immediate action requirements.
2Ease of operation
If the request for power adjustment is made too early, then the customer convenience is improved, but the accuracy of power demand and supply balance control is reduced due to fluctuations in estimated demand
Solution Approach 1:
The system dynamically adjusts the timing and granularity of power adjustment requests based on the actual demand-supply situation. Rather than using a fixed early notification schedule, the control apparatus continuously updates its estimates closer to the execution time and adapts the request timing to balance customer convenience with control accuracy, allowing flexible adjustment of the notification lead time.
3Device complexity
If the power adjustment request is made at a fixed time, then the system simplicity is maintained, but the adaptability to changing customer availability and demand fluctuations is reduced
Solution Approach 1:
The system incorporates feedback mechanisms where customers provide information about their energy storage capacity and availability, and the control apparatus uses this feedback to adjust future power adjustment requests. The system learns from customer responses and demand patterns to optimize request timing and amounts, maintaining relative system simplicity while improving adaptability through iterative refinement based on actual operational data.

AI summary
A power demand and supply control apparatus includes a target value acquiring unit, an information collecting unit, an adjustment amount determining unit, and a communication unit. The acquiring unit acquires a target value of a total adjustment amount. The collecting unit collects information of registered power amount of each of the requesting targets. The determining unit determines an adjustment amount for each of the requesting targets based on the registered power amount of each of the requesting targets and the target value of the total adjustment amount. The communication unit notifies each of the requesting targets of the adjustment amount determined. The information of the registered power amount includes information of an executable time and date. The determining unit extracts a requesting target that has the executable time and date included in the power adjustment execution time and date, and determines the adjustment amount.
