DIgSILENT remains the industry standard for power system analysis due to its integrated approach. DIgSILENT releases PowerFactory 2025

As of April 2026, the current version is PowerFactory 2026, officially released on February 4, 2026. A subsequent service pack, PowerFactory 2026 SP1, was released on March 11, 2026, to provide localized interface support for languages including English, German, Spanish, Turkish, and Chinese. 1. Key Features in PowerFactory 2026

Focusing on high-performance simulation, PowerFactory 2026 introduces several key enhancements:

Performance & Stability: Improved data loading/viewing for large networks, plus new impedance-based stability analysis for inverter-based resources.

Simulation Advancements: Parallelized EMT simulation through network partitioning and enhanced Modelica hybrid modeling capabilities.

Expanded Analysis: New DC short-circuit support and updated contingency analysis. 2. Notable Updates from PowerFactory 2025

The 2025 release introduced significant UI and usability improvements:

Interface: Native dark mode and highly flexible, customizable window layouts. Protection Library:

Project Management: New .pfdx file format for easier sharing and updated filter layers for visualizing complex network diagrams. 3. Support Status for Older Versions

DIgSILENT supports the three most recent versions, with PowerFactory 2026, 2025, and 2024 currently active. Support for PowerFactory 2023 ended in early 2026. 4. Getting Started & Training DIgSILENT releases PowerFactory 2025

Protection Library:

• New distance relay model: Siemens 7SA87 (full characteristic with power swing blocking).
• Differential protection: GE T35 with CT saturation modeling.

Known Limitations and Workarounds (as of 2025 SP2)

No software is perfect. Here are the current limitations of the latest version:

• No native Linux version – The co-simulation with RT-Linux HIL platforms requires a Windows 10 LTSC VM.
• GPU acceleration limited to EMT – RMS simulations still run on CPU only (though optimized).
• Maximum buses – 50,000 buses in load flow (single machine). Larger systems require distributed simulation (optional extra-cost module).
• Python API changes – The newly introduced pf_compute async framework is not backward-compatible; old scripts need rewriting.

DIgSILENT has promised these will be addressed in the 2026 SP1 release.

4. Co-Simulation Interface for Digital Twins

The latest version introduces a native co-simulation engine enabling simultaneous execution of PowerFactory with:

• OPAL-RT (real-time HIL)
• RTDS (real-time digital simulator)
• Python-based reinforcement learning agents (via a revamped powerfactory Python API)

This is a game-changer for hardware-in-the-loop (HIL) testing of protection relays and grid codes.

4. Enhanced IEC 61850 Model Integration

With the rise of digital substations, the latest version now includes a native IEC 61850 data model. You can directly import SCL (Substation Configuration Language) files into the single-line diagram.

• What’s new: Logical nodes (XCBR, XSWI) are mapped automatically to PowerFactory’s switch and breaker elements. Simulation of GOOSE and SV (Sampled Values) messages is now possible within the same environment, eliminating the need for co-simulation with external tools.

3. Multi-User Project Database with Real-Time Conflict Resolution

Previous versions struggled with simultaneous editing. PowerFactory 2025 SP5 introduces a PostgreSQL-based backend that allows multiple engineers to work on the same grid model simultaneously. Changes are tracked with branch-and-merge logic similar to Git.

• Key feature: Real-time conflict resolution wizard. If two users modify the same transformer tap ratio, the software highlights the discrepancy and offers automated merging options.
• Use case: Ideal for system operators (TSOs/DSOs) with teams of planners updating the base case daily.

Grid Codes:

• IEEE 2800-2022 (interconnection of inverter-based resources) – full compliance.
• ENTSO-E HVDC Code 2025 (draft implementation).
• China GB/T 19963-2024 – wind farm access rules.

Recommended for Large Models (10k+ buses + GPU acceleration):

• OS: Windows 11 Pro or Windows Server 2022
• CPU: 16 cores (Intel Xeon Gold or AMD EPYC)
• RAM: 64 GB (128 GB for transient stability with 100+ generators)
• GPU: NVIDIA RTX 4070 or higher (12 GB VRAM minimum), CUDA 12.2 support
• Storage: 1 TB NVMe SSD
• Display: Dual 4K monitors (3840x2160)

Important: The latest version does not support 32-bit operating systems or Windows 7. It also no longer officially supports macOS via virtualization (though some users report success with Parallels 19+).
