Load modelling at low voltage using continuous measurements

Abstract

The paper presents the results of load modelling at low voltage level of transformer station (TS) 10/0.4 kV/kV supplying predominantly the residential load. The necessary data is obtained from a recording device and measuring information system for continuous measurements permanently installed in the concerned distribution network. The identified parameters of static exponential load model are classified according to day periods and days of the week, and statistically analysed in order to obtain reliable parameter estimates. These are compared with literature data for the same residential load class. Possibilities for further application of the described load modelling procedure are listed.
