In practice, the droop curves that are used by generators on large electrical grids are not necessarily linear or the same, and may be adjusted by operators. This mode allows synchronous generators to run in parallel, so that loads are shared among generators with the same droop curve in proportion to their power rating. With droop speed control, when the grid is operating at maximum operating frequency, the prime mover's power is reduced to zero, and when the grid is at minimum operating frequency, the power is set to 100%, and intermediate values at other operating frequencies. It works by controlling the rate of power produced by the prime mover according to the grid frequency. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases.
