Implementation of distribution automation into medium and low voltage grids is gaining more and more support amongst distribution grid operators. In order to assess the feasibility and usefulness of dynamic network reconfiguration for the purpose of reducing losses and increasing available network capacity, it is necessary to know to what extent simultaneity amongst MV/LV transformers within distribution networks occurs. Measurements have been done in parts of the distribution network of Enexis, one of the largest distribution network operators in the Netherlands. For a full year, in 30 MV/LV substations the transformer and all outgoing low voltage feeders have been measured. In this paper the measurement data is being analyzed in order to determine the degree of simultaneity in low voltage distribution grids, both seen from the low- and the medium-voltage level. The results of this analysis will be used to assess the feasibility of power flow optimization by using distribution automation. Furthermore, an example of a field application will be simulated and discussed.
