Abstract

The invention discloses a wind farm power generation capacity control method which comprises adding a rotational kinetic energy reserve constraint condition as a penalty function to a power generationcapacity objective function to obtain a fitness function; calculating a fitness value corresponding to each individual according to the measured real-time wind speed of each wind turbine generator asper a fitness function; determining the individual optimal fitness value and the overall optimal fitness value corresponding to each individual; conducting iteration updating on the speed and the position of each individual according to the optimal fitness value and the overall optimal fitness value of each individual to obtain the overall optimal position; controlling a converter and a variablepitch controller of each wind turbine generator according to the overall optimal position. The rotating kinetic energy storage is utilized as conditions, the power generation capacity is maximized, and the wind energy utilization rate is improved. The invention discloses a wind farm power generation capacity control system and device and a computer readable storage medium with the above advantages.

Description

technical field [0001] The present application relates to the technical field of wind farms, and in particular to a wind farm power generation control method, a power generation control system, power generation control equipment, and a computer-readable storage medium. Background technique [0002] The existing power grid dominated by thermal power units can support the grid frequency by increasing the active power of thermal power units when the frequency of the grid drops, thereby ensuring the stable operation of the power grid. However, the maximum active power that can be output by wind turbines is limited by the wind speed, so the support for the grid frequency is limited. With the rapid increase of wind power installed capacity, in order to ensure the safe and stable operation of the power grid, it is necessary to improve the power grid frequency support capability of wind turbines. [0003] At present, due to the high cost of batteries, and the pollution and aging pr...
