Abstract:

The highly efficient electromagnetic transient (EMT) simulation of hybrid modular multilevel converter (MMC) is an important basis for the related research about hybrid MMC. However, because there are various kinds of sub-modules (SMs) can be employed, and a lot of power electronic switches are included in each kind of SMs, the detailed EMT model of hybrid MMC will reduce the simulation efficiency seriously. In view of this background, the unified dynamic averaging equivalent model of the series structure of various SMs is proposed based on the switching function and the dynamic characteristic of capacitor. In addition, a unified terminal highly efficiency EMT model of hybrid MMC based on the proposed dynamic model of the series structure is also presented and analyzed. The proposed unified model not only is convenient but also has the great simulation accuracy and efficiency, which has good portability and is especially important for a research tool to satisfy the convenience demand of modification. Finally, the simulation accuracy and efficiency of the proposed model are validated by the comparison with the detailed model based on the simulation components in ADPSS.
