Abstract

In this paper, the grid-interconnection requirements of directly connected medium voltage (MV) SiC-based converters are studied and the necessary control implementations are detailed. These power electronic converters use the interconnection standard IEEE 1547-2018, but can also have additional controls supported by the microgrid standards IEEE 2030.7, which is demonstrated in this work. Additionally, the grid applications realized by these directly connected MV power electronic converters at distribution system scale are defined in this paper and demonstrated through results. The controls for the studied grid applications are then developed and implemented on the controller.The paper also includes details of the controller design, and validations of controller through hardware-in-the-loop results.
