Despite the small capacity, it is enough to guarantee that power output complies with the forecast for 15 minutes, as the battery is used to eliminate the difference rather than provide full output. In certain cases, the increased predictability can be used to take wind power penetration from 20 to 30 or 40 percent. The battery cost can be retrieved by selling burst power on demand and reducing backup needs from gas plants. Presently, grid systems with large wind penetration require a small increase in the frequency of usage of natural gas spinning reserve power plants to prevent a loss of electric power if there is no wind. At low wind power penetration, this is less of an issue. There is no generally accepted maximum level of wind penetration.
Accordingly, content spinning refers to this process of rewriting an article with the above explained purpose in mind. In two of the courses I teach, my students must submit 12 texts over 15 weeks. The first 11 of those texts must be checked with the Virtual Writing Tutor grammar checker and have all avoidable errors eliminated.
However, the construction and maintenance costs are considerably higher. To assess prospective wind power sites a probability distribution function is often fit to the observed wind speed data. Different locations will have different wind speed distributions.

Electrical utilities continue to study the effects of large-scale penetration of wind generation on system stability and economics. Wind energy penetration is the fraction of energy produced by wind compared with the total generation. Wind power’s share of worldwide electricity usage at the end of 2018 was 4.8%, up from 3.5% in 2015. Unlike fueled generating plants, the capacity factor is affected by several parameters, including the variability of the wind at the site and the size of the generator relative to the turbine’s swept area. A small generator would be cheaper and achieve a higher capacity factor but would produce less electric power in high winds.

The Weibull model closely mirrors the actual distribution of hourly/ten-minute wind speeds at many locations. The Weibull factor is often close to 2 and therefore a Rayleigh distribution can be used as a less accurate, but simpler model. Of this, “between 72 and 170 TW could be extracted in a practical and cost-competitive manner”. He concluded that somewhere between 18 TW and 68 TW could be extracted.
