In this paper power system dynamic state esti-mation problem is studied considering random communicationpacket losses. Two sorts of stochastic processes, i.i.d. processand Markov process, are respectively utilized to model twodifferent communication packet losses cases. The first case onlyconsiders packet losses rate, and the second case includes bothof packet losses rate and recovery rate. The degradation ofthe performance of state estimation caused by communicationpacket losses is analyzed on IEEE 14 buses test system, andnumerical results are given.
