MODELING DAILY LOAD CURVES OF THE ELEMENTS OF 6–10 kV URBAN POWER DISTRIBUTION NETWORKS UNDER CONDITIONS OF LIMITED INPUT INFORMATION

Abstract

The paper considers the technique of modeling daily schedules of active and reactive loads of 6–10 kV dis-
tribution network sections with the following set of input data:
– typical daily schedules of active and reactive power of consumers supplied through the appropriate sec-
tions of networks, which are cited in reference literature;
– information of the energy sales company on consumer supply for a billing month;
– parameters of networks and rated values of power transformers;
– information on types of consumers connected to each power transformer;
– degree of non-uniform consumption on various specific days of the billing month.
Approximation of hourly average values of active and reactive power to their real values with the methods
under consideration is achievable taking into account an uneven power consumption both during the day and on
weekdays or weekends.
