Castelli and Benini [21] presented a comparison of the annual energy output (AEO) of two vertical-axis wind turbines (VAWTs) for the low-wind urban site of Trieste, Italy. One turbine was based on drag force, while other was lift-driven. As expected, the higher AEO was recorded for the lift-driven turbine.

Thorntonbank Wind Farm, using 5 MW turbines REpower 5M in the North Sea off the coast of Belgium A wind turbine is a device that converts the kinetic energy of wind into electrical energy.As of 2020, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 650 gigawatts of power, with 60 GW added each year.

This results in increased power per unit area, generated by VAWTs as compared to HAWTs in wind farms [1], [2]. The efficiency of VAWTs is low as compared to HAWTs as a single blade of the turbine produces maximum torque at a given instance of time in a complete rotation. Other major disadvantage of VAWT is the dynamic stall of the

Vertical-axis wind turbines can produce electrical power at lower speeds and at a variety of changing speeds. Because they vary widely in speed, the AC generators they use do not produce a constant output. Usually, the output goes to an inverter that converts it to standard AC (either single-phase or three-phase).

Vertical axis wind turbines (VAWTs) are advantageous than horizontal axis wind turbines (HAWTs) in terms of portability and ease of application in urban areas and turbulent environments.
