Description

technical field

[0001] The invention relates to a method in the technical field of wind power generation power forecasting, in particular to a method for establishing a wind speed power conversion probability model based on a mathematical statistical method. Background technique

[0002] With the rapid development of wind power generation, the output power of wind power has strong randomness, and the current prediction level cannot meet the needs of the actual operation of the power system. Accurate wind power prediction is conducive to the power dispatching department to arrange the power generation plan of the regional power system , to ensure the power quality and reduce the reserve capacity of the system, which is of great significance for reducing the operating cost of the power system.

[0003] In the current wind power forecasting system, an important link is to realize the conversion from wind speed to power under the premise of known forecast wind speed data, which ...
