For the efficiency and simplicity of electric systems, the dc power electronic systems are widely used in a variety of applications such as electric vehicles, ships, aircraft and also in homes. In these systems, there could be a number of dynamic interactions and frequency coupling between network and loads and other converters. Hence, timedomain simulations are usually required to consider such a complex system behavior. However, simulations in the timedomain may increase the calculation time and the
utilization of computer memory. Furthermore, frequency coupling driven by multiple converters with different switching frequency or harmonics from acdc converters
makes that harmonics and frequency coupling are both problems of ac system and challenges of dc system. This paper presents a modeling and simulation method for a
large dc power electronic system by using Harmonic State Space (HSS) modeling. Through this method, the required computation time and CPU memory can be reduced,
where this faster simulation can be an advantage of a large network simulation. Besides, the achieved results show the same results as the nonlinear timedomain simulation.
Furthermore, the HSS modeling can describe how the frequency components are coupled with each other through the different switching frequency of each converter.
