A kind of wind power active power control distribution method and system

Abstract

The invention relates to a wind electricity active power control distribution method and system. The method includes the steps: acquiring wind electricity active power total adjustment amount; reading basic information needed by calculating comprehensive scores of wind electricity plants when the update period of the comprehensive scores of the wind electricity plants is achieved, calculating a comprehensive score of each wind electricity plant, and generating or updating a power reduction wind electricity plant queue and a power rising wind electricity plant queue according to the comprehensive score of each wind electricity plant; sequentially performing power reduction distribution for the wind electricity plants in the power reduction queue or power rising distribution for the wind electricity plants in the power rising queue according to the wind electricity active power adjusting direction. Real-time running data of the wind electricity plants are combined, scoring and sequencing are performed based on performance indicators of the grid-connected technology of the wind electricity plants, wind electricity fluctuation can be timely restrained, three dispatching principles are embodied, calculation and power distribution of maximum force output can be adjusted by the wind electricity plants in real time when power rises, top spin of the wind electricity plants is considered, wind electricity force output is maximized, and the wind electricity admitting capacity of a grid is improved.

Description

technical field

[0001] The invention relates to the technical field of wind power, in particular to a method and system for controlling and distributing wind power active power. Background technique

[0002] The wind power installed capacity and wind power generation capacity of the power grid are increasing day by day, and the uncertainty and randomness of wind power have brought unprecedented challenges to the stable operation of the power grid. At present, the automatic adjustment capability of thermal power units can no longer completely stabilize the large and violent fluctuations of wind power output. In addition, the existing wind power control methods have low efficiency, slow speed, and adjustment lag, which makes ACE adjustment difficult and seriously exceeds the limit; at the same time, it also limits wind power. The full use of resources has resulted in unnecessary waste of wind resources; and the lack of rapid response capabilities in the case of accidents has s...
