Although the wind power development has made great achievements, but the wind power industry in China is still an infant industry that is still at the initial stage.” New Energy and National Energy Board, deputy director of renewable energy, said Shi Lishan, the current the country’s total wind power installed capacity of 800 million kilowatts of electric power is still very low weight, power generation, the proportion of total generating capacity of less than 0.5%.

Impressive scale wind power development, but problems in the development of more and more prominent. The first is the installed capacity is large, but electricity is still very low, efficient power generation time is short, do not create an effective supplement to the power grid, can not form a stable output power grid; followed by the wind turbine grid stability, there is no guarantee, especially in the wind Electrical large-scale grid, the grid impact and damage is very serious and will inevitably lead to network problems; there is a high failure rate, maintenance costs of large wind turbine is no guarantee of safety. These issues have become the wind power industry in the face of important issues.

Europe and the United States, wind power is a decentralized network used in a way, these countries are relatively small-scale wind farm. When the wind speed and wind direction vary greatly, the wind turbine unstable, unable to meet and network conditions, this time off-grid wind turbine at any time; wind turbine stable, but also the network at any time, and the power grid in several European countries are networked, a strong power grid will not have much impact on the power grid.

In China, large-scale grid used in a way, China’s wind energy resource-rich regions are mainly distributed in the northwest, northeast, north of the “three north” region and the southeast coast. Currently in the “Three North” planned six 10 million kilowatts of wind power base, but these areas is relatively weak grid areas, the grid of wind power is facing overwhelming problems. At present countries have to start planning for smart grid construction, but because these areas are in the end power, capacity, poor regulatory capacity, it is difficult to withstand the impact of changes in the wind TVU capacity.

China’s wind power project is also faced with numerous technical difficulties, are still unable to overcome, which makes the majority of the project is idle, such as Inner Mongolia, last year’s total installed capacity of Zhuozi County reach 10 million kilowatt hours and sent wind generator the system due to the capacity of poor grid, power plants the electricity generated in the local digestion and could not finish, also send outgoing not go out. Nearly half of the wind turbine is idle, only 2 / 3 of wind power on the Internet.
