Abstract: An auxiliary power source is configured to black start a power plant. The auxiliary power source includes a first power source having an auxiliary generator driven by an auxiliary drive. The auxiliary power source also includes a second power source having energy storage. The auxiliary power source is configured to supply power from the first and second power sources to support the black start of the power plant.

Abstract: Systems and methods for first time synchronization of a generator with an electrical grid are disclosed. According to one embodiment of the disclosure, a method of first time synchronization of a generator with an electrical grid can be provided. The method may include receiving, during an acceleration of a turbine, a voltage of a generator and a voltage of an electrical grid; receiving, during an acceleration of a turbine, a frequency of the generator and a frequency of the electrical grid; receiving, during an acceleration of a turbine, one or more phase angles of the generator and one or more phase angles of the electrical grid; when the frequency of the generator matches with the frequency of the electrical grid, at least one of the one or more phase angles of the generator match with the respective at least one of the one or more phase angles of the electrical grid, and the difference between the voltage of the generator and the voltage of the electrical grid reaches a threshold voltage difference, synchronizing the generator to the electrical grid by closing a generator breaker or by closing a line breaker. The method may further include: determining the generator is synchronized to the electrical grid; and increasing the voltage of the generator to match the voltage of the electrical grid.
