GridSuite v2.33.0

🎯 New Features

Contingency List & Filter Improvements

• Not-found reporting on contingency counts: Actions server and filter server now return the list of contingency lists/filters not found, in addition to total counts (#163, #194)

Busbar Section Naming Strategy

• Auto-generated BBS IDs from backend: Bus bar section IDs are now suggested by the backend using the configured naming strategy, replacing manual input (#3795, #782)
• BBS naming applied in connectivity forms: The new naming strategy is applied to bus bar sections when creating voltage levels in connectivity forms (attaching lines, splitting lines) (#3846, #3855)

Shunt Compensator Q Measurement

• Q measurement modification: Users can now modify the reactive power (Q) measurement directly from the shunt compensator modification dialog (#3812, #784, #330)

Short-Circuit Voltage Level Preservation

• Voltage level retained when ISC extension is missing: Short-circuit results now preserve the voltage level ID even when the ISC extension is null or missing for one-bus computations (#199, #195)

Load Flow Result Persistence

• Load flow result saving via API: Load flow results can now be saved to the database through a dedicated API call, decoupled from the computation run (#229)

Node Build Safety Check

• Branch build guard: Study server now validates that no node in the entire branch is currently being built before allowing further operations (#966)

Dynamic Simulation Parameters Migration

• DS parameters relocated to DS server: Dynamic simulation parameters are now managed directly by the dynamic simulation server, removing the dependency on the study server (#969, #3827)

🎨 UI/UX Improvements

Persistent View State

• NAD viewbox persistence: The NAD diagram viewbox is now saved to localStorage so the view is restored when reopening (#3845)
• Tree panel viewport persistence: The network modification tree panel viewport is also persisted across sessions (#3836)

Per-Table Global Filters

• Recent filters tracked per spreadsheet table: Recent global filters are now stored and managed independently per table, preventing unintended cross-table sharing (#3813, #106)

Network Modification Table

• Tooltips on modification action icons: Icon buttons in the network modification table now display descriptive tooltips on hover (#3806)

Security Analysis Result Table

• Non-sortable columns visually disabled: Spreadsheet columns that are not supported by the backend for sorting are now clearly disabled in the security analysis result table (#3838)

Network Modification Tree

• Fit-view at initialization: The network modification tree now correctly fits the view when first rendered (#3819)

Dialog Usability

• Stable voltage level creation dialog height: The voltage level creation dialog height no longer shifts when switching between tabs (#3853)

Sensitivity Analysis Configuration

• Global build status parameter: A new globalBuildStatus parameter is now available in sensitivity analysis configuration (#3764)

🔧 Technical Improvements

SpringBoot 3.5.11 Upgrade

• Backend dependency bump: All backend servers upgraded to SpringBoot 3.5.11 (actions-server #161, cgmes-gl-server #64, config-notification-server #80, config-server #98, deployment #605, directory-notification-server #78, directory-server #240, explore-server #179, filter-server #191, gateway #165, geo-data-server #175, loadflow-server #230, network-map-server #331, network-modification-server #786, odre-server #101, report-server #146, security-analysis-server #230, sensitivity-analysis-server #165, shortcircuit-server #197, study-config-server #107, study-server #970, study-notification-server #126, user-admin-server #95, voltage-init-server #144, case-import-server #56, user-identity-oidc-replication-server #32, powsybl-network-store-server #186, powsybl-case-server #165, powsybl-single-line-diagram-server #230, powsybl-network-conversion-server #268)

Load Balancing for Concurrent Consumers

• Multi-consumer load balancing: Load balancing configuration for concurrent run consumers has been centralized in the computation library and applied across all computation servers (network-modification-server #780, security-analysis-server #228, sensitivity-analysis-server #163, shortcircuit-server #191, voltage-init-server #143, loadflow-server #228, powsybl-network-conversion-server #260)

Composite Modification Performance

• Optimized composite modification DB loading: Database loading of composite modifications containing tabular modifications is now significantly more efficient (#791)

Dedicated Composite Modification Handling

• Composite-specific API layer: Added a dedicated controller and handling path for composite modifications across the backend and frontend stack (network-modification-server #781, study-server #965, gridstudy-app #3810)

Forms Migrated to commons-ui

• Reusable modification forms: Load creation, load modification, equipment deletion, by-filter deletion, and voltage level creation/modification forms have been extracted to commons-ui, enabling shared use across GridStudy and GridExplore (gridstudy-app #3779, #3790, #3794, #3787, #3809, #3820, gridexplore-app #824, #827, #828)

AWS SDK Version Pinning

• AWS SDK pinned to 2.29.52: AWS SDK version pinned for stability in case server and network conversion server (powsybl-case-server #166, powsybl-network-conversion-server #271)
