Electrical wind generation, feasibility study and analysis in
Special attention is directed to the interpretation of wind generation characteristics and parameters found in Lebanon and linking the electrical energy to the Lebanese slectric grid.
Wind energy penetration is the fraction of energy produced by wind compared with the total generation. Wind power's share of worldwide electricity usage in 2021 was almost 7%, up from 3.5% in 2015. There is no generally accepted maximum level of wind penetration.
Since wind speed is not constant, a wind farm's annual energy production is never as much as the sum of the generator nameplate ratings multiplied by the total hours in a year. The ratio of actual productivity in a year to this theoretical maximum is called the capacity factor.
A small Quietrevolution QR5 Gorlov type vertical axis wind turbine on the roof of Bristol Beacon in Bristol, England. Measuring 3 m in diameter and 5 m high, it has a nameplate rating of 6.5 kW. Small-scale wind power is the name given to wind generation systems with the capacity to produce up to 50 kW of electrical power.
Examples of small-scale wind power projects in an urban setting can be found in New York City, where, since 2009, several building projects have capped their roofs with Gorlov-type helical wind turbines.
