In this example, we increase the number of groups by separating the transformer from the thyristor valves, producing an additional group and 9 nodes in total.
From a real-time simulation perspective, the addition of 6 nodes slows down the simulation but separating the transformer from the valves produces much smaller group equations. The states of the transformer no longer have to be precomputed 2^12 times with the valves.
Additionally, because the thyristors have RC snubbers attached to them, they are considered as a capacitive group requiring an I-type SSN interface.
