This chapter presents the enhanced grid fault characteristics of voltage source converters (VSCs). In Sect. 6.1, the resilience of \(100\%\) inverter-based power systems is discussed. The resilience is subdivided into the resilience of the grid operation and the resilience of the VSC. The resilience of the grid operation is discussed in Sect. 6.2. It contains the presentation of the necessary hardware and software configuration of direct-connected VSCs. Different control modes of these VSCs are discussed.
