Join RTE international for 3 live FREE webinars and Q&A sessions on interaction studies with VSC-HVDC links using offline and real-time simulation tools.

The increasing penetration of Power Electronic Devices (PED) within the AC network leads to higher risk of interaction of such systems between PED, network elements and/or conventional power plants. With their relatively fast controls, VSC converters can incite a series of expected or unexpected interactions on the grid.

These webinars will present theoretical background on interaction studies. We will also discuss the main technical challenges imposed by the analysis of interactions with VSC-HVDC links using EMT simulation tools (complexity of control and protection systems, confidentiality of the control and protection algorithms, simulation of large grids…)

The webinars will be illustrated by real test cases in which different HVDC manufacturers have been involved.


The webinars are now over. You can watch the recordings.
