In order to study and test the characteristics of the distributed energy resources and storages embedded in the microgrids, it is important to combine the real-time digital simulation and dynamic physical simulation. The condition that the hardware-under-test (HUT) is active puts forward higher requirement for the interface algorithm in terms of both stability and accuracy. An impedance tracking algorithm for simplified damping impedance method (SDIM) interface is designed to achieve real-time impedance matching of the HUT with power sources (active). A novel interface algorithm is proposed. It uses the ideal transformer model (ITM) interface to drive the physical HUT and employs the SDIM interface to obtain accurate response in the virtual electrical system. The results of MATLAB simulation show that the novel interface combines the merits of the SDIM interface and the ITM interface when the HUT is active.
