Multilevel Converters for Step-Up-Transformer-Less Direct Integration of Renewable Generation Units with Medium Voltage Smart Microgrids

Chapter


Abstract


  • For grid integration of renewable generation units, a power frequency

    transformer operated at 50 or 60 Hz is generally used to step-up the low output

    voltage (usually B690 V) to the medium voltage level (typically 6–36 kV).

    Because of the heavy weight and large size of the power frequency step-up

    transformer, the grid integration system can be expensive and complex for

    installation and maintenance. To achieve a compact and lightweight direct grid

    connection, a medium voltage multilevel converter may be an alternative

    approach. Different multilevel converter topologies with switching and control

    issues are analyzed for their medium voltage applications. The practical implementation

    issues are also reported in this chapter. It is expected that the medium

    voltage multilevel converter would have great potential for future renewable

    generation and smart microgrid applications.
