Level of dispersion in dispersed particle filter

In the paper an impact of the calculations dispersion level in a power system on the estimation quality has been presented. The dispersion level has been changed from the smallest (calculations for the whole system) to the largest (individual calculations in each node of the system). The obtained results have been compared with the estimation quality of dispersed case of extended Kalman filter. Based on the performed simulation it has been concluded that the dispersion has positive influence on the estimation quality of dispersed particle filter method, but only to a certain level, i.e. in case of power system division into very small parts, unsatisfactory results have been obtained.
