Primary data processing problems in the RES generation forecasting systems

The paper presents an analysis of the main problems and methods of primary processing and data filtering in the tasks of automating the forecasting of electrical generation for renewable energy sources. The comparative analysis on the design factor of the wind generator power used was performed in case of different distribution functions (power and logarithmic) and in the absence of reducing to altitude as the calculation example. In each of the cases analyzed, a comparative analysis was performed based on the calculation of the Weibull distribution function.
