Noteworthy New Features and Notable Changes
Core and Sensitivity Analysis
- IIDM 1.16: Implementation of multiple active operational limits groups.
- Sensitivity Analysis API: Added operator strategies to the API.
PowSyBl Open Load Flow
- AC DC Load Flow: First implementation featuring DC detailed components for single synchronous components.
- Operator Strategies: New support for DC Sensitivity Analysis, including filtered and threshold conditions, and three windings transformer terminal connection actions.
- HVDC Emulation: Added HVDC AC emulation outer loop for both AC and DC calculations.
PowSyBl OpenRAO
- Time-coupled Module: Introduction of new MIP generator constraints.
- Optimisation: Handled cumulative effects of RA limitation in multi-curative optimisation during second preventive; aligned computation units with the objective function.
- Modeling: Support for German point-to-point HVDC equivalent models.
powsybl-dynawo and PowSyBl Diagram
- Dynawo: Management of additional IIDM extensions and network modifications before export; prefix parameters handling.
- Diagram: Implementation of the Atlas2 algorithm to optimize NAD layout and enriched NAD metadata to allow for full SVG generation.
