The demand profiles were defined using real data provided from the commercial companies and distributor and transport system operators detailed in Table 7.


**Table 7.** Demand load profiles data source [65,80–84].

From all the sources, real hourly demand curves for the 365 days of 2015 were obtained. Then, to determine the sixteen standard demand profiles used in ε calculation (Table 4), the next steps were followed:


The normalised demand profiles obtained are shown in Figures 8–11.
