Abstract
At the moment, the Russian wind energy market uses wind power plants, which have their own range of parameters and characteristics. There are also various methods by which it is possible to calculate electricity generation by nominal capacity and wind potential data for the site where the construction of a wind farm is planned. But for this, it is necessary to have a power characteristic for a particular wind power plant. The nominal wind speed is often used for its construction. (Research purpose) Applied analytical and computational methods, in particular the Binov method, the method of approximation of the function - linear interpolation, this is a way to calculate the intermediate value of the function from its already known several values. (Materials and methods) Applied analytical and computational methods, in particular the Binov method and the linear interpolation method. (Results and discussion) Formulas for calculating wind speed and active power for constructing power characteristics using the Binov method were given. Approaches to modeling the power characteristic and its approximation are described. At the same time, we took into account the features of power management systems, which are divided into active, passive and combined. The results of calculations were presented in tabular form, indicating that cubic polynomials cannot be used with passive and combined control systems due to a large approximation error; this indicates that common methods for determining power and output do not always give accurate results. (Conclusions) Several mathematical models used to analyze the power characteristics of wind power plants have been demonstrated. They have shown that they can be used to predict production for given sites with a known wind regime.
