Numerical studies of the impact of dirt, icing and eroded of wind turbine blades on power production were carried out. Two scenarios of wind turbine operation control, standard and advanced, were analyzed. The shape of ice covered and eroded profiles was developed based on experimental results and observations of real turbine blades. It has been shown that in the case of an ice-covered, dirty and eroded turbine blade, power production can decrease by approximately 50%, 16% and 12.5%, respectively. The influence of the decrease in power production on the capacity factor was analyzed. Using the example of a location in the Baltic Sea, it has been shown that the capacity factor can decrease by 0.023% and additionally by about 0.005% with an increase in the share of days with dirty blades in the year by another 10%.
