The power plant includes a gas turbine operable to power a first generator that is synchronized to the power grid and to produce an exhaust gas, the gas turbine operated at a power level that defines a non-zero first MW margin and including a first control system having a first droop setting, and a heat recovery steam generator (HRSG) operable to generate high pressure steam in response to the passage of the exhaust gas through the HRSG. A steam turbine is operable to power a second generator that is synchronized to the power grid, the steam turbine is operated at a power level that defines a non-zero second MW margin and includes a second control system having a second droop setting, the second droop setting set to a value based at least in part on the second MW margin. The first control system calculates the first droop setting based at least in part on the first MW margin, the second droop setting, the second MW margin, and a regional required total droop for the combination of the gas turbine and the steam turbine."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Combined cycle frequency control system and method","description":"A power plant is operable to provide primary frequency control for a grid.
