Black start is the process of gradually restoring the entire power system by restoring the power supply capability of power plants that do not have self-start capability in the power system under the premise that only power plants with self-start capability and available power sources within the power system are used to provide power [2].
The traditional black start power sources are hydroelectric units and gas engines, as well as large diesel generators and thermal power units that can switch loads quickly. The new energy black start power supply is mainly undertaken by photovoltaic power plants and wind power plants.
Power plants are under constant pressure to provide a supply of energy – continuously, in flexible operation or on demand. This means dealing with frequent fluctuations in demand and handling major incidents such as blackouts. When a severe failure in the power network occurs, black starts are key to getting things back up and running.
