The studied distribution grid is presented in the Fig. 1 and
Fig. 2. Fig. 1 represents the part of the grid with one supply
station and Fig. 2 depicts the second supply station with the
some customers. The 110 kV level is represented just by the
110/6 kV Transformer. The 110 kV and 20 kV lines are
connecting the near cities so they are not taken into
consideration. In Fig.2, the LV grid is represented by a load.
The LV grid has 7 sections and each section has 8 households.
