In this paper the approach of implementing the phasor measurement units (PMU) into the state estimation method in order to improve the power system monitoring at the distribution level will be presented. The possibility of using accurate synchronized measurement data for the simulation to enhance the calculation of the power system state will be presented. The simulation will be performed on an example network with dispersed generation (DG) and the results of the approach will be shown and discussed.
