the challenge
Electrical grids are rapidly evolving with the integration of renewable energy, storage systems, and DC loads. Managing these dynamics in DC grids requires a deep understanding of system components like power converters and filters as well as effective coordination between converters and protection devices – a task that is particularly challenging. HIL testing is increasingly vital for validating control algorithms and protection strategies before hardware deployment and is likely to become a formal standard soon. It enables system-level validation, as testing multiple components with a controller is often impractical due to cost and complexity. The main limitation is the lack of accurate models for off-the-shelf components, since manufacturers rarely provide them.
The solution
What is the solution we are seeking?
Reliable simulation models for converters and circuit breakers that can be easily integrated into HIL environments to simplify stability analysis and protection strategies while reducing development time and costs.
The solution should define a standardized, replicable modeling process, applicable across different components, without relying on proprietary data, enabling characterization of off-the-shelf converters using minimal data. We are looking for electrical models and not for models of standard AC devices or internal component dynamics (e.g. thermal or mechanical behavior).
customer impact
What is the impact of the solution for the market/customers?
Fast and reliable simulations are essential to innovate with confidence. By creating accurate digital models, we can perform real-time simulations based on multi-source information, enabling us to validate ideas quickly.
Implementing Hardware-in-the-Loop (HIL) simulations will support the development and validation of control algorithms and protection strategies, strengthening customer trust in ABB’s expertise in DC solutions.
