Description: The world currently uses about 13 terawatts (TW) of energy, and it is predicted by 2050, an additional 10 TW will be required. Not only that, the additional energy required will be have to be carbon neutral. Considering all of this, what is the role of solar energy?
( Hydroelectric energy could provide about 0.5 TW, tides and oceans could chip in 2 TW and wind power could blow 2 – 4 TW) Solar energy striking the earth amounts to 120,000 TW, yet only 0.01 – 0.04 of current energy usage is derived from solar sources. In theory, one hour’s solar irradiation is enough to supply a year’s global energy demands.Solar flux at ground level is approximately 340 W/m2 in the world’s sunniest areas.

Description: Currently one of the fastest growing industries in the renewable
energy is wind power, which demonstrates its rapid and sustainable
development of globally. Assessment WWEA [ 3] In 2011, the total capacity of wind power -
power plants ( WPP) was 237,016 MW. Best results achieved so-called
large (network ) , wind energy , jointly working with electric network. high
the level of development of wind power contributed to various programs conducted in
the leading countries of the world wind power ( the U.S., China , Germany , Spain , etc.).

Description: s a clean renewable energy, wind energy draws more
and more attention around the world. In case of high wind speed
or low speed but substantial installed wind power capacity, wind
turbine generators (WTGs) will take the place of traditional
power plant partly. Under the circumstance, the transient
stability will change. Therefore, in this article, the synthetical
dynamic model of WTG is introduced first, and on the basis of it,
the article focus on the comparison of transient stability
characteristic between wind farm based on double fed induction
