Abstract: A system includes a turbine system that contains a heat recovery steam generator (HRSG) having a flow path that receives an exhaust gas, and having a fluid path that receives a fluid. The fluid path is adjacent to the flow path such that the fluid is heated by the exhaust gas. The HRSG includes an electrical heater that provides heat to the fluid path during a start-up mode of the HRSG, during a shutdown mode of the HRSG, or both.

Abstract: The present application provides an energy control computing device for adjusting one or more steam flow parameters delivered to a steam turbine from a heat recovery steam generator via a number of control devices. The energy control computing device includes a processor in communication with a memory. The processor is programmed to receive a number of measured operating values, identify steam turbine operating limits, identify a number of candidate operating modes meeting steam turbine operating limits, selecting the candidate operating mode maximizing the steam flow parameters while not exceeding the steam turbine operating limits, and directing the control devices to meet the selected candidate operating mode.
