Microgrid library / Generic Elements / Unconnected ports

Question

Hello,

A number of Generic modeling elements, e.g., 'Variable Load (Generic)', along with associated UI, etc., are present under the Microgrid library in the Schematic Editor. Obviously, this is the state-of-the-art modeling approach currently followed at Typhoon HIL.

None of these Generic elements is available in 'single-phase' mode. Given that 'warnings' and/or 'errors' may arise due to the presence of unconnected ports, is it advisable to use these modeling elements to emulate 'single-phase' mode, i.e., connect one of the phases and the neutral to the rest of the model/circuit, according to modeling needs?

Any ideas?

Thanks

Hello Ioannis,

If the generic models are built for three-phase applications, it doesn't make sense to use it on a single-phase simulation. You'll probably get misleading behavior.

In the examples of THCC you have a single-phase grid connected microinverter and a single-phase PV inverter that might be useful as starting point.

Thanks Ricardo,
I was looking for single-phase loads because they fit into my case study but since such modules are not yet available, I will proceed with using the three phase ones. Hope that in future, single-phase generic loads along with their UI will be available, as well.
Best,
Ioannis
