October 2025: Delivered Dynamic Simulation enhancements in pypowsybl/pypowsybl, focusing on reliability, usability, and performance. Implemented optional report nodes and resource bundles for reporting, and streamlined API access by making event_mapping and timeSeriesMapping optional and consolidating dynamic curve retrieval into a single get_dynamic_curves API. These changes reduce integration friction, improve automation, and support more scalable simulation workflows for planning and operations.

In September 2025, delivered notable improvements to powsybl-core focused on API simplification, dynamic model metadata management, and robustness of dynamic security analysis. The work reduces maintenance overhead, enhances developer experience, and increases runtime reliability for network modeling workloads. Key outcomes include removing deprecated API surfaces, introducing a Dynamic Model Info extension to link model names with network elements, and hardening the Dynamic Security Analysis path with null-safety measures and accompanying tests.

Summary for 2025-08: Delivered Terminal Power Filtering Enhancements in gridsuite/commons-ui, expanding the expert filter component with new terminal power filters (P, Q) and their absolute values (P_ABSOLUTE, Q_ABSOLUTE). This required updates to constants, translations (English and French), and extending FieldType with new enum values to enable precise power-related filtering and analytics. The change is implemented in commit 70b1bf682d8e46019a80893c5a470b39b8df4719 (Add generator filter on terminal P, Q, P absolute and Q absolute). This work enhances data-driven decision-making by enabling targeted filtering of power metrics, improving UX for bilingual users, and strengthening data maintainability. No major bugs fixed this month; focus was on feature delivery and code quality improvements.
