|---|---|---|
According to the grid codes, grid-connected converters should have the low-voltage ride-through (LVRT) and voltage support abilities. In this paper, a flexible control strategy for the modular multi-level converter (MMC) is presented. First, the mathematical models based on Kirchhoff's laws of MMC are analyzed, and a flexible coordinated controller, which is to protect the multi operating variables in the MMC system and implemented in the d-q coordinate, is proposed. In order to achieve the voltage support capability for MMC, the proper injected power can be deduced considering the line characteristic. Finally, the simulating results from MATLAB/Simulink, and the experimental results from a scaled-down MMC prototype are presented to verify the feasibility of the proposed control strategy. |
