Control strategy to smooth wind power output using battery energy ...
The generated wind power output is directly proportional to the cube of wind speed, P w = 1 / 2 ρ A v 3, where ρ is density, A is the area, and v is the velocity (wind speed). Since wind speed presents random fluctuations the wind output power will fluctuate and result in the issues of system stability and reliability.

For a single turbine, the following equation describes power output: P. (1) P = 1 2 ρ π R r 2 C p w 3. The terms ρ, R r and w refer to the density of air, the rotor radius and the wind speed respectively. Meanwhile, C p is the power coefficient of the proportion of available power, that the turbine is able to extract.

How Much Energy Does A Wind Turbine Produce?
For the 4 kW wind turbine, we''ll assume the turbine is 40m high. Average wind speed is about 6.5 m/s, giving an average power output of 900W (from power curve). Average energy per day is 900W x 24h = 21,600 Wh or 21.6 kWh. Obviously the relative energy outputs are very dependent on location.
How is the power of a wind turbine calculated?
The formula above shows that the power output of a wind turbine is a cube function of incoming wind velocity. Thus if you can access a 2x windier location (e.g., 12 m/s versus 6 m/s), this does not simply double the available power output. It octuples it (2^3=8). This explains the industry''s push towards offshore wind, where wind speeds are ...

These data provide annual average wind power density in watts per one square meter of a turbine sweep area. Average speeds in the table are based on the so-called Rayleigh speed distribution and are given for the sea level. To get the same density above sea level, the air speed has to increase by 3% per 1000 metre (1% per 1000 ft) elevation.
