195-204: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Refetch when the new SLD settings change.

fetchDiagram reads networkVisuParams.singleLineDiagramParameters.measurements and observability, but the effect does not depend on these values or fetchDiagram. When UPDATE_NETWORK_VISUALIZATION_PARAMETERS updates either setting, the mounted SLD can rerender without issuing a new request. Add both settings to the dependency list.

PowSyBl network-viewer single line diagram API measurements observability useStateEstimationVisualisation

💡 Result:

In the PowSyBl ecosystem, network visualization is managed through a modular architecture that separates diagram generation from rendering. The core components for your query are as follows: 1. Diagram Generation: The powsybl-diagram library is responsible for generating network diagrams (single-line diagrams and network-area diagrams) in SVG format from an IIDM network model [1][2]. This process produces both the SVG content and corresponding metadata (JSON), which are essential for interactivity [3][4]. 2. Frontend Visualization: The @powsybl/network-viewer (and its core subset @powsybl/network-viewer-core) provides a TypeScript library for integrating these diagrams into frontend projects (Angular, Vue, or Vanilla JS) [3][5]. The SingleLineDiagramViewer component takes the SVG content and metadata to render the diagram in the browser [3][4]. 3. Observability and Measurements: PowSyBl supports the integration of real-time electrical data into these diagrams [2]. Measurements (such as voltage levels, angles, or flow values) can be overlaid on the generated diagrams using custom component libraries, CSS, and configurable labels [1][2]. While the diagram generator creates the base SVG, the frontend viewer allows you to bind this electrical data—often provided by backend state estimation or load flow calculations—to the diagram elements [2]. 4. State Estimation Visualization: While there is no specific single API method named useStateEstimationVisualisation, the observability of state estimation results is achieved by applying the solved electrical values (from tools like pypowsybl.network.Network.apply_solved_values) to the network model [6]. Once these values are applied to the network, you can generate the diagrams and configure the visual representation to reflect the state estimation results, such as by color-coding equipment or displaying calculated voltage/angle values [2][6]. For Python-based workflows, the pypowsybl library provides convenient high-level methods to generate these diagrams [7], and the pypowsybl-jupyter project offers Jupyter widgets that integrate the viewer for interactive analysis in notebooks [8][9].

🌐 Web query:

site:github.com/gridsuite "useStateEstimationVisualisation" OR "singleLineDiagramParameters" measurements observability

💡 Result:

In the context of GridSuite, useStateEstimationVisualisation refers to functionality within the study configuration and network visualization framework, particularly related to how state estimation results and parameters are presented in single-line diagrams (SLDs) and other network views [1][2][3]. Recent updates have focused on enhancing state estimation observability and configuration management [3]: Configuration and Parameters: New configuration parameters have been introduced to manage state estimation studies, including boolean flags for specific study configuration activation [1][2][4]. These parameters are handled through services such as the study-config-server, which manage NetworkVisualizationParam entities [1][2][5]. Observability and Visualization: - GridSuite now supports enhanced observability for state estimation, including the ability to manage custom SLD configurations for state estimation studies [2][4]. - Measurements, such as active and reactive power for generators and HVDC VSC converter stations, are exposed within editing forms and dialogs to support state estimation analysis [3]. - Single-line diagrams have been enriched to provide better context, including the display of short-circuit current (ICC) values in legends and improved bus legend information [6][7][3]. - The platform includes a broader observability stack, often utilizing Grafana dashboards and alerting rules to monitor GridSuite services, which supports the overall observability of the power system analysis environment [3]. These features are part of the broader GridSuite ecosystem, which uses PowSyBl libraries to generate SVG-based single-line diagrams and manage network data [8]. Network visualization parameters define how these diagrams are rendered, including options for line paths and other visual elements [5][3].

🌐 Web query:

site:github.com/gridsuite "observability" "measurements" "svg-and-metadata" single line diagram

💡 Result:

In the context of power grid software systems like GridSuite and PowSyBl, a single line diagram (SLD) is generated as a combination of an SVG file and associated metadata [1]. The SVG file provides the visual representation of the network elements, while the metadata is essential for maintaining the logical links between these graphical elements and the underlying network elements, such as original network IDs, topology, and operational measurements [1]. This architectural approach allows observability measurements—such as active power (P), reactive power (Q), or short-circuit current (ICC)—to be dynamically injected into the diagrams [2][3]. Systems typically follow this workflow: 1. Computation: A dedicated server performs calculations (e.g., short-circuit analysis or load flow) [3][4]. 2. Data Injection: Relevant observability data or measurement results are retrieved and mapped to the existing diagram structure [5][2]. 3. Visualization: The single line diagram server uses this metadata to update the SVG, such as adding or refreshing values in legends or displaying status-specific indicators (e.g., greying out values if a load flow study has not been executed) [5][3][4]. This separation ensures that the graphical layout remains consistent while allowing the observational data layer to be updated asynchronously as system states change [1][3].

Refetch SLD diagrams when visualization parameters change

useEffect in src/components/workspace/diagrams/sld/use-sld-diagram.ts:195-204 does not depend on networkVisuParams or its measurements and observability fields. A settings change can therefore leave the mounted diagram rendered from the previous request. Add the relevant dependencies or trigger a refetch when these parameters change.
