Microgrid Design & Analysis in Simulink

[electroctopus]

People experienced with designing and analyzing microgrids on Simulink- I have a question.

This model (link below) uses 1MW PV, 1MWh BESS and 600Vac load supply voltage.

I want to modify this to have 350kW PV, 350kW/750kWh BESS and load supply voltage of 240Vac.

Any idea how we can easily do this?
