Performance Enhancement of a Battery-Grid Connected SiC MMC for DC Microgrid Systems
Book Contribution - Book Chapter Conference Contribution
The modular multilevel converter (MMC) is a recently developed and advanced alternative power converter in the high and medium voltage applications. It is suitable for the DC microgrid systems to effectively integrate the distributed power systems such as battery energy storage systems, wind power systems, and solar photovoltaic systems. In this paper, a battery-based SiC-MMC with 17 submodules per arm for efficient DC-microgrid systems is investigated in terms of its mathematical modelling, control and thermal modeling. The modeling and analysis of the MMC show that the output voltage and output current have good performance with low harmonic distortion. The comparison of power losses shows that the SiC semiconductors have superior performance over conventional Si-based switches in the high-power applications.
