| Sumario: | The integration of renewable energy sources into modern distribution grids is accelerating the development and deployment of advanced power electronics solutions. Multiport converters (MPCs) offer a promising approach by integrating multiple ac and dc ports into a single device, improving efficiency, cost-effectiveness, and grid resiliency. This article presents a nonisolated medium-voltage (MV) MPC with a modular multilevel converter (MMC) architecture in the ac–dc ports. Two control approaches, classical strategy and crossed strategy, are compared to evaluate their performance under normal and abnormal conditions, respectively. The study presents modifications to enhance ac and dc fault-ride-through. The control strategies are validated through time-domain simulations using TyphoonSim and a Typhoon control hardware-in-the-loop (CHIL) setup. |
