Hey guys
I'm reading an article called "Online grid impedance estimation for single-phase grid-connected systems using PQ variations". I'm sending it attached.
In page 3 it is said that "...the difficulty in the estimation of Zg is that the voltage source of the grid (Vs) is immeasurable..."
Why? Can someone explain it to me?
