Voltages at the most “remote Bus” for the selected prosumer options with 5 kW of solar power/house and 2 kVA at 0.85 PF household loads, without and with the utility LDC option. Note: the feeder’s P (reverse power flow) and Q demand are also shown for each combination.
|Prosumer option||Without LDC||With LDC|
|22 kV substation voltage = 1.02 pu||22 kV substation voltage = 0.985 pu|
|Most remote Bus voltage (pu)||Pfeeder(MW)||Qfeeder(Mvar)||Most remote Bus voltage (pu)||Pfeeder(MW)||Qfeeder(Mvar)|
|Do nothing – solar inverters at 1 PF||1.084||−2.280||0.865||1.049||−2.275||0.873|
|Solar inverters at 0.95 PF (absorbing)||1.059||−2.226||2.111||1.025||−2.216||2.122|
|Q(V) ±0.9 PF (as per Fig. 3)||1.058||−2.213||2.053||1.041||−2.260||1.197|
