The control of charging and discharging operation discussed above will be applied to a simple three phase four wire test feeder shown in Fig. 6. The LV section of this test feeder is ideally similar to the LV feeders in Australian distribution networks. Typical electric appliances used in residential households were used to model the aggregate loads at the different phases of the test feeder. The PV inverter sizes at the residential households were limited within a range of 2-4 kW. PV penetration at a given time instant was defined as the ratio of the actual PV output at any PCC to the actual active power load at the time instant considered.
