Control System Design

Grid-forming power converters

Tailored control design for your grid-forming or grid-connected application

The transition to grid-forming converters as part of the system stability roadmap significantly affects the control of new converter generations. The “FNN Hinweispapier netzbildende Eigenschaften” defines the requirements for grid-forming power converters. We support you in implementing the guidelines and reduce your time-to-market!

Development, Validation and Certification — One Partner, Complete Solutions.

Development of grid-forming and grid-connected power converter control

Design &
Implementation

We develop new control strategies for
grid-forming, grid-following, and
hybrid operating modes.

Simulation & Validation

 

Our control solutions are tested from
simulation through laboratory validation. 

Integration with IP protection

We tailor solutions to your specific
requirements while ensuring full protection of your intellectual property throughout the entire development cycle.

Optimization of existing controllers in terms of stability and grid compliance

Retrofit & Upgrade

We upgrade and adapt existing controls to ensure compliance with emerging guidelines and existing national and international standards.

Stability Analyses

We evaluate resonance stability and control performance for various different grid scenarios and conditions to optimize your control. 

Performance-Tuning

We improve the dynamics, efficiency, and robustness of your systems through targeted adjustments and practical testing.

Evaluation of system stability and grid-forming properties

Stability and
conformity testing

We examine the robustness, protection requirements and control quality of your prototype or product. 

Advanced
Testing Methods

We offer combination of simulation, power hardware- in-the-loop testing and extensive laboratory infrastructure for comprehensive results. 

From Microgrid to Grid-Tied operation

With over 80.000 m² (>11 football fields) of laboratory infrastructure, we enable large-scale microgrid testing and offer diverse low- and medium-voltage grid topologies using real components.
