适用于多种子模块拓扑的储能型模块化多电平变换器通用高效仿真模型

To address the issue of the large simulation scale of energy storage-embedded Modular Multilevel Converters (ES-MMC) and the poor versatility of conventional high-performance models, a General and Efficient simulation Model (GEM) is proposed in this paper, which simultaneously leads to the development of an improved average value model (AVM). Both GEM and the improved AVM are constructed based on the equivalence of the arm, with the distinction that GEM takes into account each submodule, while AVM should be regarded as a multiplication of a single submodule. In the simulation study of ES-MMC, both GEM and the improved AVM have the capability to reduce simulation time while maintaining accuracy significantly. Furthermore, the two models also perform well in the simulate scenarios involving the blocking of the ES-MMC. In the case study section, the accuracy, versatility, and high-performance characteristics of the GEM and the improved AVM are validated through a detailed comparison with the detailed switching model.
