Prequalification -Testing & Models

Grid-forming power converters

The demands placed on modern energy systems are constantly growing. To ensure that your systems comply with current and future connection guidelines, we offer comprehensive testing and prequalification services.

In our state-of-the-art laboratories, we simulate and test your systems under realistic conditions. In doing so, we develop generic models that serve as the basis for precise analyses and simulations. We use these models to evaluate the stability of your system and test its ability to form grids in accordance with the latest system stability roadmap.

Our tests go beyond simple compliance checks: we consider both current requirements and future challenges to ensure that your systems remain reliable and powerful in the long term. With our expertise, we accompany you on the path to successful prequalification – for secure, stable, and future-oriented system integration.

Tests for future-ready system integration
