Abstract

The invention provides a wind power generation prediction method, a device and equipment, belonging to the technical field of power generation prediction. A method for predict wind power generation isprovide in an embodiment of that invention, Installations and equipment, obtaining the meteorological value of the point to be measured at a fixed time, and extracting wind data from the meteorological value of the point to be measured, wind data are then processed, to convert the wind data into a plurality of class data, Then the calculation factors of the point to be measured are obtained, andcombined with the calculation factors, a plurality of class data are processed to determine the corrected wind value, and finally the power generation power of the point to be measured is predicted according to the corrected wind value, so that the output power of the wind farm for a long time can be accurately predicted, and the accuracy of the grid dispatching task assignment can be improved.

Description

technical field [0001] The present invention relates to the technical field of power generation prediction, in particular to a wind power generation prediction method, device and equipment. Background technique [0002] In recent years, energy conservation and emission reduction, green energy, development of low-carbon economy, and sustainable development have become the focus of attention of all countries. Clean energy and renewable energy account for an increasing proportion of energy in various countries, especially wind energy has become the focus of today's development. Speed ​​comes first in energy. The driving force of wind power generation is wind energy, and wind energy has strong randomness and volatility, which makes the wind power connected to the grid show severe fluctuation characteristics. [0003] At present, in order to reduce the impact of wind power grid-connected on the system, it is necessary to predict the wind power of wind farms in advance. There are...
