Simulation and Assessment of Wind Array Power Variations Based on Simultaneous Wind Speed Measurements

A wind model for relating wind speeds based on simultaneous wind speed measurements at several sites is developed for both meteorological events and turbulence wind conditions. The wind model is used to perform an analysis and simulation of wind power variations from single and multiple wind turbine arrays for meteorological events and turbulence. The results indicate that serious reduction in operating reliability and economy can occur for meteorological event induced wind power variations when total wind power generation capacity exceeds spinning reserve levels on a utility. The effects of turbulence induced variations are shown to be small for 5% wind penetration on a large utility but quite serious for the same penetration level on a small utility.
