In this network, the PV system is rated at $250$ kW$.$ The grid is rated at $2500$ MVA and the X$/$R ratio is $7.$ At first, you need to change the system MVA from $2500$ MVA to $1$ MVA gradually to observe the impact of voltage variation at bus B$1($Keeping the X$/$R ratio at $7).$ After that you need to change the X$/$R ratio from $7$ to $1$ gradually $($Keeping the MVA constant$)$ to observe the impact of voltage variation at bus B$1.$ You need to change various set$-$points of the system and change the strength of the system to understand and explain the impact of these variations on the system.
