High wind speed hysteresis

A storm control is typically implemented in the control software of a wind turbine to increase the stability of the power output for wind events close to the cut-out limit. The mean wind speed at the Norwegian offshore areas range between 9–11 ms−1. A high mean wind speed increases the risk of wind events where … See more The total power in the atmosphere for a wind turbine to extract is the power density at hour t (Pd (t)), and is expressed by the following relation: which gives us the amount of kinetic energy contained in the air per square … See more Turbine specifications pose limitations to the theoretical power potential. The generated power at hour t (Pw (t)) is the wind power that can be produced for a specific turbine, and … See more Equation 11 gives the total kinetic energy in the air per square meter. Since the extracted wind energy is a function of the turbine diameter, and hence the rotor disk area (A), we multiply Eq. 11by the sweep area A to get the … See more The atmospheric wind power is directly proportional to the air density (see Eq. 11).
