The proposed hybrid approach is implemented to an hourly electricity load
series for period 1 October to 1 December 2016, which the pattern is shown
in Figure 4(a). Based on the w-correlation matrix described in Figure 4(b), we
can define four groups, namely G1, G2, G3, and G4. The first group, G1, consists
of the eighty-six first eigentriples. The second group, G2, is formed from the
th
th
87 eigentriple to the 140 eigentriple while the third, G3, is constructed from
th
the 141 eigentriple to 289 eigentriple and the rest is the last group. The
st
separability between groups can be seen in Figure 4(c). The four subseries
depicted in Figure 4(d), i.e. (1) , (2) , (3) and (4) , are then can be determined
by the diagonal averaging process from the corresponding groups, G1, G2, G3,
and G4, respectively.
