英文摘要	With the rapid growth in DC energy-using equipment and distributed DC power, traditional AC distribution networks increasingly have problems, such as high loss and poor flexibility. This paper studies an AC/DC hybrid system integrated with multiport solid-state transformers (SSTs) and distributed renewable energy and proposes an optimal configuration model for the AC/DC hybrid system based on a coordinate operation strategy of SSTs and energy storage. First, the composition and topology of the AC/DC hybrid system are proposed. Then, a realistic efficiency model of a multiport SST is established. Based on the minimum operating loss of the SST, a multiport SST dual-machine parallel optimal operation strategy is established. A multi-energy storage system collaborative optimization operation strategy is established based on the electricity price, grid-connected mode and synergistic relationship among each energy storage system. Finally, based on the proposed AC/DC hybrid system model, the optimization objective of the system life cycle net present cost (NPC), constraints and GA algorithm are set. The proposed method is verified by industrial scenarios. The simulation results show that the proposed model can improve the economic and efficiency of the SST integrated AC/DC hybrid system.
