KWh kilowatt does not mean, not the actual power generation capacity. As the Danish National Grid electricity market, the vice director Lai Nasuo that said: “Only when the power effectively to deliver electricity to end-users from the fans when the only value of wind energy.”
We ignore the wind power technology is still in the hard hard hard at the idea, first to give the reporter saw the interesting phenomenon, or, more precisely, a little sad phenomenon: In the interview, and even a number of wind farm developer Wind electrical equipment business, respondents were asked about wind power generators in question, almost without exception, from the passionate speech before the turn into the “Let’s just say as a friend in private”, “I can talk about the situation However, there can not be the name of our company and my. ” … … Dare not openly say that the question set to a wind power focus on this.
For the industry reflects the strong wind power and other clean energy access is difficult, the State Grid Corporation Deputy General Manager of Shu Yinbiao February 1 this year, the first positive response, he gives the explanation: “In recent years China’s wind power development much faster beyond the planning; and wind power and other renewable energy power generation is intermittent, random, low schedulability characteristics of large-scale access to the grid after the operation will have a greater impact. ”
This is indeed part of the reason, but it is also the inherent characteristics of wind energy, the proportion of China’s wind power generating capacity of only 0.7% of the total, so the proportion of poor is not a plan, the wind can be intermittent and random interpretation. Grid answer seems too easy way out.
The same grid, the face of almost the same difficulties, Inner Mongolia Power Grid has taken the lead and set an example.
Zhang Fusheng, general manager of wind turbines Inner Mongolia Electric Power Corporation, told reporters: “As of December 31, 2009, Inner Mongolia grid (excluding the eastern four-Union City) have access within the installed capacity of 4.302 million kilowatts of wind power, accounting for 20% of network boot volume, Power generation accounted for the largest load of 23.6%, accounting for 27.6% of the maximum power load, accounting for 34.7% of the minimum power supply load. wind power has become the main power in Inner Mongolia’s second largest. ”
According to the current accepted wind power in Inner Mongolia accounts for more than 20% of the actual situation, in accordance with the maximum power load of 15% of the country’s conservative estimates, Zhang Fusheng that “the admissibility of the national grid by 2015 wind power capacity of 150 million kilowatts. If you do not establish a national elimination on wind power market mechanism, wind power in remote areas does not solve the problem Songchu channel is undoubtedly the lookout power of this newly-born child abandonment, or just unearthed in the wind pressure of a big rock on the seedlings. suggest the department concerned send channel-depth study of wind power and the State Grid, China Southern Power Grid elimination on a wide range of the overall planning of wind power. ”
Inner Mongolia Power Grid can do a good job, why the State Grid, China Southern Power Grid do not? The main reason or wind power grid company touched the interests of the sensitive nerve roots.
From the NDRC Energy Research Institute, ZHOU Feng told reporters: “wind power is to spend the cost of renewable energy funds have enough money, the extra money who do not want out.”
Sinovel Technical Director of the party Hui told reporters: “wind power, the most difficult adjustment of interest, followed by the idea, once again is the technology. And the net surface is subject to technical factors difficult, but the crux of a deeper level is driven by interests, power companies in the Internet and long distance transmission of wind power needs a lot of input, but little income, lack of drive and change the dynamic of interest. technical difficulties can be overcome, the administrative system has not smoothed along, not the distribution of interests balance caused by wind power is the primary factor in the difficulties. ”
In addition, it was difficult to say that wind power is not mature and related technologies in China, a power authority, told reporters: “Technology is not the key objective that the Chinese power system even better than in Europe, equipment, technical know nothing poor, can reach the world’s most advanced level, not below any country. ”
It is no exaggeration to say that the current development of wind power in China once again to the vital moment, and solve the overall network to live, and resolved, they are difficult to sustain the development of wind power.
National Energy Bureau of new energy and renewable energy, deputy director of the history of Tateyama told reporters: “To a larger scale wind power development, and now the problem to be solved much more difficult than in the past, the past is Shebeiyanfa and other wind generators preparatory work, now involves the adjustment of the relations of production, the adjustment of interests, so this would be more difficult. how to solve network? I think it’s understanding of power. If you can recognize UHV as the same as understanding and smart grid wind power, wind power can not be resolved it? If everyone from this long-term interests of the state of democracy, fundamental interests, abandoning some of the thinking of small business, I think this matter can be resolved. There are no settlement is not the level of attainment. China’s economic development will increasingly be faced with resource environmental constraints, power companies must do something. ”
How to solve this problem, the company gradually straightened by the concept of power is tantamount to drop in the bucket, it is difficult to fundamentally solve. Newspaper that the solution in two ways: first is the Danish “fat lose the sale of electricity to separate the nature of re-positioning grid pattern; The second is to break the monopoly power split mode.
“Denmark is currently in force generation, transmission and sale of electricity completely separate the three links management system.” Danish State Grid Corporation of Han Simo root Sen said, “upstream and downstream of the sale of electricity generating companies is completely market-oriented competitors, for the middle part of the national transmission grid company into a National Climate and Energy under the non-profit organizations, most reflect the fair trade of electricity dispatch center is assigned to the national grid management. scientific power system for the wind power and other renewable energy sources and which laid the foundation for network and development. ”
Shows that the nature of the Danish national grid is defined as public bodies, not for profit, which is different in nature from the grid company in China, China Power Grid is the meaning more companies are interest groups in pursuit of profit as the main target, plus been given a strong monopoly power, in the absence of the establishment of a good “game rules”, entered the market, is bound to a “bullying the weak, strong bullying the weak” phenomenon, is difficult to reflect its share of public responsibility and social responsibility. If under the State Grid Corporation of the public sector to establish its non-profit and social responsibility, then wind power would not be facing so much difficulties.
The second solution is to split the power grid, reduce the monopoly power grid company, the introduction of market competition mechanism, such as the U.S. power grid system is the way state power independent of each other, collaborate with each other by the market mechanism. China’s vast territory, the size of each province or territory equivalent to a European country, if considered an independent power system, you can learn the advanced experience of Europe and America.
EU Chamber of Commerce in China Energy Working Group Vice-Chairman Cheng Hung told reporters: “China’s power consumption is extremely satisfied that wind power and other renewable energy potential, but due to wind and lack of coordinated planning grid construction, wind turbines forecasting system does not perfect, there is no effective regulation of the other power supply, no electricity market mechanism, coupled with the lack of relevant policies and so on, resulting in wind power problem in the rapid development of wind power in China have become increasingly prominent. “
Yicheng District, Zaozhuang City, from the government that, after several visits, Japan’s Idemitsu Co., Ltd. and Yicheng District Government on wind power projects signed a cooperation agreement. Time, such as wind to meet the requirement, the Corporation will light wind power development in Yicheng to invest 1 billion yuan, the city will set a precedent for the development of new energy industries.
It is understood that Japan’s Idemitsu Co., Ltd. was founded in 1911, is Japan’s largest integrated oil group is one of the Fortune 500. Yuan Zhen Liu Yicheng District for the location, mountain valley structure, wind speed and other indicators, is consistent with the actual wind power generation requirements, Idemitsu Co., Ltd. had been a number of site visits. The cooperation agreement signed, Liu Yuan Zhen mainly in the territory of a great number of wind towers, wind data for one year a detailed collection. Time, such as wind to meet the requirement, the company will invest 1 billion yuan in the development of wind turbines Yicheng District, building wind power plants. Development of wind power, wind energy can effectively use local resources for local high-tech industry has laid a solid foundation, to promote the transfer structure Yicheng, transfer mode implementation of the strategy, but also for tourism in Yicheng Adds a beautiful landscape.
To ensure that wind power, new energy into the grid photovoltaic power system after the safe, reliable, stable operation, recently, the National Electric Power Company in Gansu Province after combining new energy and network to run after the actual development of the “photovoltaic power plant in Gansu Province and network acceptance regulations “and the” Gansu Province, and network acceptance of wind farm regulations, “and began the trial.
State Electric Power Company, deputy chief engineer of Gansu Province, said Mr Wong, the two “require” the drawn up, clear wind power, photovoltaic and other new energy sources and networks technical requirements and testing requirements for Gansu Province in the future acceptance of new energy and net work a scientific basis, to ensure that new energy into the electricity grid system is safe, reliable and stable operation.
Wind energy resource concentration in Gansu Province, mainly represented in the Hexi Corridor in Jiuquan region, particularly the Guazhou County of Jiuquan City, Yumen desert region, and Subei Mazongshan area, the region known as “the world’s wind storage” said the wind turbines industry with the development of advantages. With the country in August 2009 approved the construction of the first and largest-scale Jiuquan wind power base of 10 million kilowatts a project started in Gansu province has begun to promote the wind power industry. As of last year, installed capacity of wind power in Gansu Province has reached 220 million kilowatts by the end of this year to achieve installed capacity of 5.16 million kilowatts will be “World Wind Library” will be transformed into a “wind power capital of the world.”
Synchronized with the construction of wind power, solar energy resource development in Gansu pace, currently the largest of the two 10-megawatt photovoltaic power plant project is construction of Dunhuang city, total investment 383 million yuan, the annual design output capacity of 33,415,700 kilowatts When will all be completed by the end of June this year, power generation.
April 13, the World Wind Energy Association (WWEA), vice president of TanaySidkiUyar announced that the Chinese wind power installed capacity has surpassed Germany (25.77 million kilowatts) ranked second in the world, reached 26.01 million kilowatts.
TanaySidkiUyar that Asia is to maintain a very high rate of growth of wind power installed capacity, of which the most prominent China, “China’s wind power on a 113% annual growth rate, ranked third in the world.”
However, this data has been wind turbines questioned from the national grid.
Professor of Chinese power, wind power experts, Huizhu that, according to her statistical data, China’s wind power capacity should be the world’s third, to 22.68 million kilowatts, and the network of generators to 16.13 million kilowatts.
“China’s wind power installed capacity in recent years continued to increase, but the actual rate of very small grid, only 40%. Wind power installed capacity ratio in the country accounted for 1.84 percent of electricity is only 0.75 percent.” Huizhu said should not only see the installed capacity of wind power, should also see the ratio of production and power generation.
An industry that was the result of different statistical results, because foreign investment and construction of China’s planned construction of wind farms are also calculated to the new installed capacity in 2009.
“This data is from the national grid dispatch center received, it will be more accurate figure.” The source said.
“At present, the total wind power generators has reached 25.8 million kilowatts.” And the Danish Investment Promotion Agency standard is more recognized investment manager Caiyan Global Wind Energy Council of 12 published data, the figure and the figures of Chinese Wind Energy Association, agreed.
April 9 afternoon, Guidong County and GD Power Development Co., Ltd. Zhuhai Branch held a county Bamian Mountain Wind Power Conference, and the signing ceremony, marking the county wind energy will be another new industry.
Guidong County is mountainous counties, high mountains and steep slope, wind resources are relatively abundant, especially those located in the county west of Bamian Mountain elevation 1,500 meters above the ridge prominent and stretching over 40 kilometers, is rich in wind turbines resources. In the study of Song Mountain is located in the state-owned forest floor, four are rural and the East Los Township and other townships, the State Power Zhuhai Branch of the head of that county at the prospect of wind power generation.
Currently, the project has entered the production stage. Expected to set up a wind farm, installed capacity of 300,000 kilowatts.
Entered after 2010, Dafeng wind turbines company several security organizations, learning and field fan control, taking the time to each fan for an intensive screening of defects and problems will be included in the check processing equipment needed pooling, use of weather control wind serious flaws eliminate the problem by Typhoon aircraft, the formation of closed-loop security device management, it will not only ensure the efficient operation of each fan, but also the entire substation equipment to be always safe operation of wind power generator over the audience also plans small “secret”, a quarter for the first time created a generating capacity of 131.5 million kwh of new records.
Danish state-owned energy company DONG Wednesday said the company has bid the world’s largest wind farm one of the coastal wind power project, the capacity of 400 MW wind farm is expected to invest 10 billion shillings (18 million).
Wind farm is located near the Danish Kattegat Anholt Island side of the wind farm is expected to begin early 2012 power supply, 2013.
Wind completed, it will replace the Dong in the North Sea, 209-megawatt wind farm to become the world’s current largest wind farm, but it will be another seat in the London Array DONG garden capacity of 630 MW wind farm under construction in par .
DONG said the wind turbines farm will supply enough families Denmark 400 000 zero carbon electricity, accounting for Denmark 4% of total electricity consumption.
