Abstract

Wind fluctuations result in even larger wind power fluctuations because the power of wind is proportional to the cube of the wind speed. This report analyzes wind power fluctuations to investigate inertial power smoothing, in particular for the frequency range of 0.08 - 0.5 Hz. Due to the growing penetration rate of wind power, the susceptibility of the power system to power fluctuations increases. Wind turbines operating at a higher rotational speed compared to optimal tip speed ratio's have the ability to smooth power. However, the efficiency of a wind turbine with inertial power smoothing capabilities will be lower. Full inertial power smoothing for fluctuations of 0.01Hz and higher will decrease the overall wind turbines efficiency with less than 1.5%.
