Abstract

The invention provides a simulation generation method for wind speed data of multiple wind power farms. The method includes the steps that according to historical data of wind speeds of the multiple wind power farms, delay time among the wind speeds is determined; a model for the wind speeds of the multiple wind power farms is constructed through a Copula function theory, and the constructing step includes the substeps that marginal distribution of all the wind speeds is determined, the suitable Copula function model is selected, model parameters are estimated, and the model is evaluated; the wind speeds of the multiple wind power farms are generated according to the constructed Copula function model; the wind speeds generated in a simulation mode are reconstructed and adjusted in the aspect of the time sequence through a stochastic differential equation and a delay relation. The simulation generation method for the wind speed data of the multiple wind power farms can meet fluctuation characteristics of the respective wind speeds of the wind power farms and the cross correlation among the wind speeds of the multiple wind power farms.

Description

technical field [0001] The invention relates to the field of renewable energy power generation, in particular to a method for simulating and generating wind speed data of multiple wind farms. Background technique [0002] In recent years, my country's wind power generation has developed rapidly, and several 10 million-kilowatt wind power bases have been built and put into use. Although the wind speed has strong randomness and uncertainty, due to the close geographical location of multiple wind farms, they are basically in the same wind belt, and there will be a strong correlation between wind speeds. It is of great significance for the study of large-scale wind power integration systems to comprehensively consider the variation law of wind speed of multiple wind farms and establish a wind speed model of multiple wind farms. [0003] At present, a lot of research has been done on the methods of generating wind speed and wind power data of a single wind farm at home and abroa...
