Topology and Control Research on Hybrid AC/DC Power Supply Equipment for Inland Port

Within inland ports, there has been rapid development of large-scale new energy generation, efficient energy storage systems, and high-penetration distributed power generation. The adoption of direct current grid integration for new energy sources offers higher efficiency. In the future, flexible interconnected AC/DC grids will play an indispensable role and become a crucial form in constructing the next generation of power grids. This paper analyzes the control topology and control strategies at various levels of flexible AC/DC interconnection devices within inland ports. Control strategies are simulated to validate their feasibility.
