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 |
