3. Consider the microgrid of Figure. A three-phase transformer, T1, is rated 500 kVA, 220/440, transformer with the reactance of 3.5%. The microgrid is supplied from an AC bus of a PV generating station with its DC bus rated at 540 V. The distribution line is 10 miles long and has a series impedance of 0.1 +1 1.0 A 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/13.2 kV with the reactance of 8%. Compute the per unit impedance diagram of the microgrid system. Assume the voltage base of 13.2 kV on the local power grid side and kVA base of 500. 151 Load 1 DC Bus AC Bus PV DC Bus PV Generating Station DCDG -OCAC Boost Inverter Converter TI BE LOGIN Power Grid T2 Lond-2
