Title: Analysis of errors in distribution networks power losses calculations with relation to the time discretization intervals
Keywords: power losses, energy losses, discretization interval, form factor, load profile, electric power and energy measurements

Abstract: The paper examines the errors occurring in power loss evaluation for electrical distribution networks as a result of the different (increased) duration of the time discretization intervals used for the step approximation of the load profiles of the supplied consumers. The relation between these errors and the magnitude of the index called “form factor” is also a subject of interest. Using the estimations of errors in function of the single time interval duration for each particular value of the form factor, and calculating the real magnitude of the form factor for the respective network, one could decide about the proper discretization interval for particular cases of networks supplying various types of consumers. The developed methodology could be further used in more comprehensive studies for definite clarification of the considered relations.
