An application of experimental design to the modelling of electrical power distribution systems

This paper presents results obtained from simulation studies on the effect of uncertain input data on the calculation of output characteristics of power distribution systems. An investigation of input data errors and their influence on systems analysis results has a particular importance in real-time modelling of power systems. The simulation experiment was carried out for a numerical model of an existing radially operated power distribution system of 15 kV. Design of experiments was a procedure for selection of a number and conditions of realisation of experiments. The theory of experimental design allows us to construct and experimentally verify the qualitative model of power distribution system to analyse a significance of each component in distribution system modelling
