Islanded Operation of an Inverter-based Microgrid Using Droop Control ...
At 1 s, the total microgrid load is increased from 450kW/100kvar to 850kW/200kvar. At 3 s, droop control is enabled on all inverters. We can see that the microgrid load is now shared equally among the three inverters. At 5 s, the supervisory control is enabled. The frequency is then being slowly increased to 60Hz and the line voltage to 600V.
