Abstract: An electric power system provides a coordinated and controlled intercommunication and operation of power engineering equipment and converters, e.g., rotating AC machines, power electronic converters and transformers as well as power grids in order to enhance electric power produced by renewable facilities. As viewed from the power grid and its stakeholders' perspective, enhanced renewable facilities are more stiff than conventional renewable facilities, and produce power that is as commercially valuable and fungible as electric power produced by traditional plants such as fossil fuel power plants, hydroelectric plants, nuclear plants and the like. xMs and SMs, or more generally yMs, fulfill the demands of stiffness and reduced variability, which have conventionally limited the commercial usefulness of a large scale use of renewables delivering power to a power grid.

Abstract: A power plant includes a gas turbine coupled to an electric generator. The electric generator can be connected to a high-voltage network through a generator switch and can be operated as a motor for the start-up of the gas turbine. The electric generator can also be connected to a static starting device for the run-up of the gas turbine.
