Weightage: 20% 1. Consider a microgrid that is fed from a PV generating station with AC bus voltage of 120 V as shown in Fig. The modulation Index for the inverter is 0.95. Compute the following: 1) The per unit model of the load ii) The per unit impedance of transformers T 1 and T2 ii) The per unit power for the transformer T1 and T2 iv) The per unit value of line impedance v) The per unit equivalent impedance and give the impedance diagram. Assume the base voltage, Vb of 220 V in the load circuit and the Sb of 450 kVA. 151 120 V PV Module ZL = 1.2 +1 120 十 totoo T2 DC/AC YA Converter T 500 KVA 220/13.2 KV 550 KVA 2+j5 22 Sload 475 KVA p.f = 0.75 lag 13.2/220 KV 550 KVA 3+j8 22
