Network bottleneck is the greatest challenge wind power development
Network bottleneck is the biggest challenge wind power development. As of the end of 2008 China has more than 12 million kilowatts of wind power units to complete lifting, in which 10 million kilowatts of wind turbine can generate electricity had passed through debugging, but because of power grid construction is lagging behind, as well as wind power in some of the technical, economic and regulatory barriers, 2008 the actual end of the power grid, wind power installed capacity of only 8 million kilowatts, power factor caused by the waste capacity of about 200 million kilowatts.
The state power grid power grid enterprises in supporting the construction of wind farms have not done enough policy support, leading to wind power grid construction in China is lagging behind. Technically speaking, the weak the strong wind resources, wind power has not stability, small-scale wind power can cause power quality, voltage problems, large-scale wind power can cause power grid stability and wind generators other issues. Therefore, if you do not increase the input power, regional power grid would be a serious threat; while if there are problems, it will cause large-scale power outages lead to disastrous consequences. Other power supplies such as thermal power, hydropower, can all be scheduled, which greatly reduces the risk of power grid operation and dispatch. In addition to the technical level factors, low economic efficiency, operation and management of the complex impact of wind power is an important reason why the Internet.
According to the state encourage renewable energy development policies, power companies must accept in full and purchase of renewable energy capacity. However, Northwest, Northeast and North China is China’s wind power resources are relatively rich regions, but most of these areas in the peripheral power is relatively weak power grid construction zone. The difficult problem of wind power the Internet is not only China, the world’s wind power in almost all developed countries have similar problems in the short term is difficult to solve.
China Electric Power Research Center by the vertical and horizontal view, as our focus on the development of clean energy, wind power generation industry’s rise inevitable, in this process, wind power generation equipment and power grid construction would restrict development of the industry, in order to make wind power generation industry, to maintain high speed, stable, long-term development, we must resolve two issues.
