Consider the microgrid of Figure 3.66. A three-phase transformer, T1, is rated at 500 kVA, 220 VY grounded/440 V delta, a transformerwith a reactance of 3.5%.Themicrogridis supplied from anAC bus of a PV generating station.The DC bus rated at 540 V.The distributionlineis 10mileslong and has a series impedance of 0.1 + j1.0 Ω per mile and local load of 100 kVA at 440 V. The microgrid is connected to the local power grid using a three-phase transformer T2, rated at 440 V Y grounded/13.2 kV delta,500 kVA with a reactance of 8%. Compute the per unitimpedance diagram of the microgrid system. Assume the voltage base of 13.2 kV on the local power grid side and kVA base of 500
