Description

technical field [0001] The present invention relates to the technical field of wind farm optimization dispatching, in particular to a wind farm power dispatching method, device and electronic equipment. Background technique [0002] Improving the power regulation capability of wind farms is a powerful way to ensure the healthy grid connection of wind power and the stable operation of the grid. In the process of wind farm power regulation, the power dispatching command of the grid dispatching center is usually issued to each grid-connected wind turbine in the wind farm according to the dispatching method adopted. [0003] Most of the existing wind farm scheduling methods in engineering use the weight distribution algorithm according to wind speed, but only by wind speed to optimize the scheduling in the wind farm, the scheduling scheme obtained often has a large error, because it cannot consider the performance of the wind turbine in the actual operation process. In the actu...

Problems solved by technology

Especially in high-load conditions, there are relatively many power tasks assigned to each unit, and due to the uncertain differences in the actual output of the units, it is impossible to match the power tasks of the fans with their output characteristics simply by distributing them according to the wind speed , the units with high output levels are limited by their own power tasks and cannot fully exert their output capabilities, while the units with low output levels are limited by their own output capabilities and cannot complete power tasks, which leads to the output power of the wind farm not reaching To the requirements of dispatching instructions, reducing the efficiency of power dispatching of wind farms
