On Comprehensive Description and Analysis of MMC Control Design: Simulation and Experimental Study
نویسندگان
چکیده
This paper presents an evolution of control systems Modular Multilevel Converters (MMCs) focusing on the internal voltages and currents dynamics. MMCs have passive components inside converter that create extra dynamics compared to conventional VSCs. Some schemes do not consider these may still stabilize system asymptotically thanks linearisation in modulation step. However are less robust because they prone poor damped oscillations dc side converter. The MMC circuit energy relationships presented this paper. Along with a gradual development based control, important roles each clearly demonstrated. Experimental results show impacts step behaviour.
