Hi everyone, I have initializing question about renewable in dynamic simulation.
In my case, I build a PV plant which using the machine control mode "Fixed Q based on WPF". The voltage at machine side is 0.97 p.u. under power flow solution.
In dynamic simulation, I use PVGU1 and PVEU1 as this PV plant's model. When I initialize the case, The initial condition of this machine's voltage at machine side becomes 0.79 p.u., which cause the initial condition suspect I guess.
I don't know what and why cause a such voltage deviation. Please give me some advise, thank you.
