Typical Load Profiles
Figure 7-1, Figure 7-2 and Figure 7-3 show typical demand profiles for residential, commercial and CBD customer segments.
Figure 7-1 Typical residential demand profile
The key characteristics of the residential demand profile are the distinct morning and evening peaks and the significant difference in demand between summer and winter profiles, where in absolute usage terms, the latter is almost double the former. The profiles show the characteristics at an 11 kV distribution feeder level rather than an individual customer profile. Capturing the profiles at this level in the network hierarchy shows a diversified demand profile illustration clearly the length of the evening winter peak which can extend upwards of three hours. There is no evidence of significant solar/PV in the summer profile which would show up as significantly reduced demand from late morning until late afternoon.
