Hierarchical Structural Model of AC/DC Power Systems

Abstract:

The hierarchical decomposition and modeling method of large-scale power systems proposed previously is expanded to be suitable for AC/DC power systems in this paper. In the new model of AC/DC systems, DC systems will have the same position as AC systems. The components in AC/DC power systems are classified into three categories, namely conversion components, DC components and AC components. By analyzing the difference between DC interface and AC interface, the unified structural model suitable for any kind of component in AC/DC systems is built. Then, the hierarchical structural model is derived based on the hierarchical decomposition method. The main characteristics of the proposed AC/DC model are the same as that of previous AC model.
