10kV Four-Port Solid-State Transformer

to simulate a four-port solid-state transformer (SST) for a large-scale system consisting of a total of 578 switches, each rated at 1MW. The system diagram and the circuit simulation model in DSIM are shown in the following figure:

simulate the dynamic process of 0.2 seconds, DSIM only takes about 20 seconds, and it is very close to the simulation results of other power electronics commercial software, with a relative error of less than 0.01 percent, as shown in the figure below.
