I have considered battery in BUS=204 and PV in place of generator (from the attached circuit). Here, Battery is initially charging and in GFM mode and PV is in GFL mode (by default). I have written the below code and attached are the outcome.
My queries are-
a) The Battery was initially in charging condition (in code) but here its zero (outcome) and after breaker reclosing the breaker starts supplying. Which is not following GFM mode.
b) The PV initially provides power and after Breaker closing it never supply. Unable to understand why.
