Description
I am working on modelling photovoltaic power plants electrical grids. When adding inductors to the model, it fails to solve. The model without the inductances is solid and works properly. I have already tried diferent types of solvers, but no results. I get the error:
Failed to solve linear system of equations (no. 517) at time 0.000000, system is singular for U[2, 2].
The default linear solver fails, the fallback solver with total pivoting is started at time 0.000000. That might raise performance issues, for more information use -lv LOG_LS.
