Quantitative analysis model of wind energy resources in adjacent area of existing wind farms

Abstract

Abstract To accurately analyze the risk resource reserves in the vicinity of wind farms and optimize the application of wind energy resources, a quantitative analysis model of wind energy resources in the vicinity of existing wind farms considering the roughness index and interference characteristics is studied. Collect and preprocess the wind energy resource data in the vicinity of existing wind farms in the national meteorological-related Internet, and build a risk resource analysis index system consisting of wind energy density, roughness index and interference characteristics according to relevant national standards; The parameter estimation method of Weibull distribution is used to calculate the density index of wind energy resources and the available hours index of wind energy resources. The roughness index is determined using the Monin–Obukhov consistent theory, and the correlation coefficient and stability are used to describe the interference characteristic index. The quantitative analysis results of wind energy resources in the vicinity of existing wind farms are obtained according to the calculation results. The experimental results show that the model can accurately calculate the roughness index and interference characteristics of the study area, and obtain high-precision quantitative analysis results for wind energy resources.
