InterACDC

The project InterACDC is to identity the possibly unwanted interactions among inverter-based generations (IBGs), synchronous machines (SMs) and HVDC transmission systems taking into account the bidirectional AC-DC dynamic couplings by:

1. establishing a more complete system model,
2. examining the applicability of existing stability analysis methods for the stability assessment of future hybrid AC/DC grids,
3. developing the required enhancements to the most promising analysis method,
4. investigating the stability impacts of various HVDC and IBG control schemes as can be classified into grid-following, grid-forming etc. and
5. developing bidirectional AC-DC dynamic coupling indicators and analyzing their stability impacts. Analytical results will be validated by time-domain stimulations and laboratory tests.
