Power Management Server With Staggered Load Adjustment Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power management systems disrupt the supply-demand balance by concentrating instantaneous power adjustments in the first half of a predetermined time interval, leading to instability in the power system.
Innovation Solution
A power management server and method that determine individual adjusted power amounts and start timings for multiple apparatuses, allowing for staggered power adjustments throughout the interval to maintain balance without interruptions, using a controller to transmit control messages specifying these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If facilities adjust power to reach individual adjusted power amounts at an early stage in the predetermined time interval, then the integrated power reaches the target faster, but the instantaneous power adjustment is concentrated in the first half of the interval causing supply-demand balance disruption
Solution Approach 1:
The patent segments the power adjustment process by dividing the predetermined time interval into multiple sub-intervals and distributing the power adjustment across different facilities at different start timings. Instead of all facilities adjusting simultaneously, the controller assigns staggered start timings to individual facilities, segmenting the concentration of instantaneous power adjustments and preventing supply-demand balance disruption.
2Productivity
If all facilities adjust power simultaneously to meet the total adjusted power amount, then the target is achieved efficiently, but the concentrated instantaneous adjustment disrupts the supply-demand balance
Solution Approach 1:
The patent implements periodic action by distributing power adjustments across multiple time periods within the predetermined interval. The controller assigns different start timings to different facilities, creating a periodic pattern of adjustments rather than a single simultaneous event. This spreads the instantaneous power adjustments across multiple time points, reducing the harmful impact on supply-demand balance while maintaining overall adjustment efficiency.

AI summary
A power management server includes a receiver configured to receive an adjustment message for adjusting a supply-demand balance of a power system; a management unit configured to manage two or more apparatuses; a controller configured to determine individual adjusted power amounts each adjusted by a respective one of the two or more apparatuses and start timings at each of which a respective one of the two or more apparatuses starts power adjustment so that a total adjusted power amount requested via the adjustment message is adjusted; and a transmitter configured to transmit a control message including an information element specifying the individual adjusted power amounts and the start timings. The controller determines the start timings that are different from each other and each of which is for a respective one of the two or more apparatuses.
