Global Simulation Model Design of Input-Serial, Output-Parallel Solid-State Transformer for Smart Grid Applications

This paper provides an overview of early attempt at developing a simulation model on solid-state transformer (SST) based input-serial and output-parallel (ISOP) topology. The proposed SST is designed as base for smart grid (SG). theoretical review the power converters under consideration, well their control techniques. Further, presents concept with PLECS circuit simulator. examines bidirectional energy flow between medium-voltage AC DC grid, while evaluating efficiency qualitative indicators grid. After completion design verification electrical properties analysis by models, synthesis offers recommendations optimal layout topology application.
