This release version 3.1.0 of OpenIPSL is led by an Industrial-Grade Model Expansion. The release significantly expands the availability of new models and examples, with broad additions across synchronous machine dynamics, governors, excitation and stabilizer systems, and WECC-type renewable energy source models (Wind, PV and BESS), while also improving compatibility and quality checks.
Highlights
Primary highlight: Industrial-Grade Model Expansion:
- Industrial-Grade Model Expansion: substantial additions and hardening of production-ready dynamic models and associated examples.
- Comprehensive model catalog growth: expanded synchronous machine, governor, excitation systems, and WECC renewable models for large-scale stability studies.
- WECC renewables energy source models (RES): WECC generic renewable models, including REGC, REEC, and REPC components for Wind/PV/BESS integration studies. Pre-defined templates with hierarchical modeling for BESS, PV and Wind.
- Expanded Microgrid and Voltage Source Models: new and updated IEEE/University Campus microgrid examples and voltage-behind-impedance source variants.
- Generic Variable Speed Drive Model: new model for variable speed drive systems with their power electronics and controller modules.
- Model quality and robustness improvements: targeted updates to key dynamic models and release checks.
- New Addition to Tutorial Examples: new example showing the integration of power flow records from GridCal/VeraGrid.
New component additions:
Key additions highlighted for this release include:
- New machine models: CIM5, CIM6, GENTPJ.
- Renewable Energy (WECC generic models): Renewable Energy Generator/Converter (REGC) models REGC_A; Renewable Energy Electric Controller (REEC) models REEC_A, REEC_B, and REEC_C; Renewable Energy Plant Controller (REPC) models REPC_A.
- Governing systems (thermal, gas, and hydro): DEGOV, IEEEG2, WEHGOV, WPIDHY, and WSIEG1.
- Excitation systems and compensators: AC7B, AC8B, DC4B, ESDC1A, ESDC2A, ESURRY, EXBAS, EXNI, SCRX, and IEEEVC.

v3.0.0...v3.0.1
Extends from Modelica.Icons.ReleaseNotes (Icon for release notes in documentation).
What's Changed
This new release version 3.0.0 of OpenIPSL is a
non-backwards compatible release based on the
Modelica Standard Library version 4.0.0.
It is feature identical with
OpenIPSL version 2.0.0
(which still uses MSL 3.2.3).
A conversion script is provided for user libraries using OpenIPSL version
2.0.0 and older. (Note: Models that extended from any of the Examples models
will have to be converted manually by the user.)

will have to be converted manually by the user.)
Highlights
- Changed the license to the
3-Clause BSD License.
- Use of SI or per-unit units only in quantities
(i.e., no more customs scaled kilo or Mega units).
- The old
Examples models have been moved under
Tests.
- The old external
Application Examples package has now been incorporated as
Examples and is part of this library.
