| description | The invention discloses a method and device for evaluating the maximum available droop coefficient of an offshore wind plant and electronic equipment. The method comprises the following steps: solving a frequency time domain analytic expression of a power system and active output expressions of a wind turbine generator and an energy storage system when a frequency fault occurs; solving a wind turbine generator rotor speed expression and an energy storage system charge state expression; taking minimization of the maximum frequency deviation as an optimization target and taking the condition that the overall active power output of the wind power plant station is not out of limit as a constraint condition, and solving a preliminary evaluation result of the maximum available droop coefficient of the wind power plant station; solving a primary evaluation result of the maximum available droop coefficient of a single machine by taking the maximum station droop coefficient as an optimization target and taking the con |
