Integral manifold model reduction(IMMD)has been applied for the analysis of distribution system with dynamic voltage regulator(DVR) in the paper.Multi time scale characteristics of the system was illustrated after building the dynamic models of distribution line, on load tap changing transformer and load. The fast dynamics can be involved within the slow dynamics by IMMD substitution. A simulation example illustrates the effectiveness of IMMD for a distribution system with DVR by reducing the simulation elapse time significantly without lowering the accuracy.
