As global electrification accelerates, building a more resilient and reliable power grid has become critical. The HVDC-WISE project, part of the Horizon Europe program, is developing smarter control and protection strategies for hybrid AC/DC systems, combining the flexibility of AC with the efficiency of HVDC.
One breakthrough is in advanced control techniques. The project improved grid-forming control by addressing its interaction with DC voltage droop, resolving issues like harmonic instability and enhancing fault recovery. Coordinated strategies – like using fuzzy logic and PI controllers – helped reduce overshoot and improve system recovery after disruptions.
To tackle wider grid needs, HVDC-WISE introduced wide area services such as frequency control and AC line emulation, managed through a decoupled control layer. This enables the grid to respond dynamically to changing conditions.
In multi-terminal DC grids, the project used model predictive control to stabilize operations, ensuring smooth transitions and managing unbalanced loads effectively.
On the protection front, HVDC-WISE emphasized the need for adaptive protection schemes suited for converter-dominated grids. Traditional approaches no longer meet the demands of modern systems.
Finally, recognizing rising cyber threats, the project developed AI-driven anomaly detection tools, integrating both physical and digital indicators for robust cybersecurity.
By advancing control, protection, and security, HVDC-WISE is setting the stage for a future-proof, flexible, and secure European energy grid.
