Network Regulation for Threshold Overshoots via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for network regulation in low voltage and medium voltage networks are inadequate in addressing threshold value overshoots, as they rely on global and coarse control commands that fail to precisely manage the contributions of controllable components, leading to potential energy inefficiencies and network constraint breaches.
Innovation Solution
A method where a central regulation unit calculates necessary corrections and transmits action instructions with incremental probability factors to controllable components, ensuring fair distribution of efforts and selecting components based on topological information to effectively manage threshold value overshoots, and informs network operators of insufficient emergency reserves.

Engineering Contradiction Analysis
1Measurement precision
If global and coarse control commands are used for network regulation, then the control system is simple to implement, but the precision of managing controllable component contributions is insufficient leading to energy inefficiencies
Solution Approach 1:
The control system segments the network into control areas and further into individual controllable components. Each component receives individualized control commands based on its specific characteristics and current state, rather than applying uniform global commands. This segmentation enables precise management of each component's contribution while maintaining system-wide coordination through the central regulation unit.
Solution Approach 2:
The regulation system applies local quality by tailoring control commands to the specific characteristics of each controllable component and its local network conditions. The central regulation unit considers topological information, component capabilities, and local threshold value deviations to generate customized control instructions, ensuring optimal local responses that collectively resolve network-wide threshold overshoots.
2Reliability
If all controllable components are activated to resolve threshold overshoots, then the threshold values are more likely to be maintained, but irrelevant components waste energy by contributing unnecessarily
Solution Approach 1:
The system segments the set of all controllable components into relevant and irrelevant subsets based on topological analysis. Only components whose control can actually influence the threshold overshoot in their specific control area are activated. This selective activation maintains threshold values reliably while preventing energy waste by leaving irrelevant components unchanged.
Solution Approach 2:
The regulation applies local quality by assessing which specific components in which control areas are actually affected by the threshold overshoot. Control commands are generated only for components located in control areas where threshold values are exceeded and where component control can effectively address the issue, avoiding unnecessary activation of components in unaffected areas.
3Productivity
If control commands are transmitted without considering topological information, then the control process is simpler, but relevant components cannot be identified leading to ineffective regulation
Solution Approach 1:
The system segments the network into control areas based on topological information, allowing the regulation process to focus on specific affected areas rather than treating the entire network uniformly. This segmentation enables efficient identification of relevant components within each control area while maintaining overall network coordination through the central regulation unit.
Solution Approach 2:
The system performs preliminary analysis of topological information and control area definitions before generating control commands. By pre-structuring the network into control areas and understanding the topological relationships, the system can quickly identify relevant components when threshold overshoots occur, improving response effectiveness without adding complex real-time analysis requirements.

AI summary
A method for network regulation upon threshold value overshoots in a low voltage or medium voltage network, wherein control commands are transmitted from a central regulation unit of the low or medium voltage network to controllable components of the low voltage or medium voltage network, where upon occurrence of the threshold value overshoot, the central regulation unit calculates the necessary correction and transmits a suitable action instruction to at least one controllable component, with each action instruction, a probability factor is also transmitted which is incrementally raised if, given an insufficient reaction of the controllable components, the threshold value overshoot is not prevented and thus an action instruction must be transmitted anew, and the central regulation unit informs the network operator if the emergency reserves of the controllable components are insufficient to prevent the threshold value overshoot.
