Abstract

A model-in-the-loop capability has been developed to emulate the dynamics of power sources within a hardware-based DC distribution system. Using this tool, time-domain models of power sources simulated faster than real-time are interfaced with hardware components at the voltage and power levels of the power system. Coupling between simulation/hardware is established through a DC/DC power converter using model/wall clock time synchronization. The capability is illustrated in the emulation of a synchronous machine/converter power source. Results of time- and frequency-domain studies are provided to validate the approach.
