Abstract: Systems and methods for black-starting a power system using a battery energy storage system can be provided. In one example implementation, a method includes obtaining, by the one or more controllers, a signal requesting a black-start of the power system using the battery energy storage system. The method further includes increasing, by one or more controllers, a system bus voltage to a nominal voltage level using the battery energy storage system for a start period according to a start ramp. The method further includes maintaining, by one or more controllers, the system bus voltage at about the nominal voltage level using the battery energy storage system during a normal period following the start period.
