Distribution Feeder Visualization With Object Limits for Responsive Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face performance issues and unresponsiveness when visualizing large distribution feeder models with behind-the-meter assets due to limited computing resources, particularly when dealing with models exceeding 5,000 objects, as they struggle to efficiently display and edit complex power distribution network topologies.
Innovation Solution
The implementation dynamically selects and displays subsets of objects in a distribution system visualization method, setting limits for node and link objects, and using conditions such as length thresholds or random selection to optimize the visualization, allowing for efficient representation of large feeder models with up to 25,000 objects or more, thereby reducing resource utilization and improving user experience.

Engineering Contradiction Analysis
1Loss of information
If all objects in a large distribution feeder model are displayed on the main map view, then complete topology visualization is achieved, but system performance deteriorates and the system becomes slow and unresponsive
Solution Approach 1:
The patent segments the distribution feeder model objects into different categories (conductive lines, transformers, switches, etc.) and applies different display strategies to each category. When the total object count exceeds the threshold, the system selectively displays only certain object types (e.g., conductive lines and transformers) while omitting others (e.g., switches and capacitors), thereby reducing the rendered object count to maintain system responsiveness while preserving essential topology information.
Solution Approach 2:
The patent extracts and prioritizes essential objects for display based on their importance to topology representation. When resource constraints are detected, the system extracts only the most critical objects (such as conductive lines that define the network structure) for display, while excluding less critical objects. This selective extraction maintains the core topology visualization while reducing computational load.
2Loss of information
If a high number of objects are displayed on the main map view, then detailed topology information is provided, but resource utilization increases causing slowdowns
Solution Approach 1:
The patent implements dynamic object selection based on real-time resource conditions and user interaction. The system continuously monitors the number of objects to be displayed and dynamically adjusts which objects are rendered. When resource utilization exceeds thresholds, the system dynamically reduces the object set by applying filtering criteria. This dynamic adaptation allows the system to maintain optimal performance while providing detailed topology information when resources are available.
3Productivity
If conductive line objects are selectively displayed based on length conditions, then visualization performance is improved, but some topology information may be omitted
Solution Approach 1:
The patent applies local quality by differentiating the display treatment of conductive line objects based on their individual characteristics (length). Instead of uniformly displaying or hiding all conductive lines, the system selectively displays lines that meet specific criteria (e.g., lines longer than a threshold length). This local differentiation ensures that visually significant conductive lines are preserved while omitting less significant ones, maintaining both performance and essential topology information.

AI summary
Example implementations described herein provide systems and methods for visualization of power distribution feeder networks. The systems and methods involve setting a limit of objects of the power distribution network to be displayed on a map, the objects comprising at least nodes and links between the nodes, the links comprising at least conductive lines; when the total number of the objects exceeds a limit, selecting one or more subsets of the conductive lines based on one or more conditions related to the conductive lines; and generating a first visualization displaying the map comprising a subset of the objects including the one or more subsets of the conductive lines, wherein a number of displayed objects is less than or equal to the limit.
