I suggest adapting DPsim GFL models to represent control and electrical filter structure of some well-known and well-accepted generic average value model (for example from https://doi.org/10.1109/TPEL.2012.2199334).
The key issues right now:
- GFL control structure in DPsim misses cross-decoupling term.
- Filter circuit includes "coupling resistor" and some of the GFL models also include optional step-up transformer. This complicates automated steady-state initialization from power flow, because inverter controls the power at the filter capacitor node. If we set the same power for PQ bus in power flow and as reference power for inverter, it will not start in steady state due to losses on coupling resistor and optional transformer. The power differences between power flow settings and time-domain simulation settings now have to be handled manually.
I suggest adding cross-decoupling term and removing coupling resistor and optional step-up transformer. This will break many existing examples. I suggest looking case by case whether to adapt them or simply remove.
