Wind power, "the Internet is difficult," was originally grid "drag"

Wind power as a clean energy in China has been widely concern. However, in recent years, although a quick going up everywhere in wind farms, but wind power Shique encounter difficulties in access. What causes wind power "on-line hard"? Is the price difficult to coordinate, or are there other "difficulties"?

In the end of the January 31 State Grid Energy Research Institute "Energy Economic Development" forum, the State Grid Corporation of India deputy general manager of Shu-Biao's words, for the first time wind power and other clean energy, to make a positive response to the difficulties faced by the Internet. He said: "In recent years the pace of development of China'swind generator far beyond the planning; but the wind power and other renewable energy power generation with intermittent, random, can be characterized by scheduling low, large-scale access to run after the power grid will have a greater impact. "

Wind generators  company shut down helpless

This winter, northerly winds and some whistling wind power enterprise "pass by."

Inner Mongolia Autonomous Region Ulanqab Huitengxile wind farm at night to stop working, wait until the morning to continue its work. Investors that there was no thought of generating units in the prairie wind there will be plenty of time to shut down, "we can only let the winter prairie wind generators giant Hula  from the 'arm' in vain to scratch among those that we of the loss. "

Abandoning the wind turbines down is that these companies quite upset. Because the western Inner Mongolia Power Grid has been able to accept more wind power.

The western Inner Mongolia Power Grid in accordance with the requirements of the total load, all wind farm to cut supply targets, all of the wind farm Ulanqab follow the schedule is: 7 am to 10 pm you can boot between the power generation; at 10 point-to-7 am the next day to rest.

Wulanchabu Huitengxile wind farm experienced a situation, a number of wind generator in Inner Mongolia a microcosm of business. According to media reports, Beijing and be able to fly international companies Yue Heng said, companies put into operation in Inner Mongolia had 700,000 kilowatts of wind power, because power consumption in western Inner Mongolia, Namibia can not only make fans abandoning the wind stops to switch. From the winter 2010 New Year's Day, the company has lost 1.8 billion kWh of electricity. State Power Longyuan New Energy, said Lai-Sheng Qi, general manager of the company in Inner Mongolia grasslands Wulanchabu wind farm, there is no power to send, there is not a high spirit, abandoning last year's winter wind down at night is particularly serious, direct economic losses have been 8,000 million, while the night is the best time to wind power.

As of the end of 2009, installed capacity of wind power in Inner Mongolia ranks first in the country. I understand that currently invest in wind power in Inner Mongolia, there are more than 60 companies, many companies are right outside the delivery of wind power is limited worried.

In fact, there are difficulties in grid

"Restricted wind power output, mainly on account of the western Inner Mongolia in the winter because of heating power to take people's livelihood, in order to ensure the power grid voltage and frequency stability, in order to ensure the safe operation of power grid will, forced to take such arrangements." Ulanqab GUO Shao-jun, deputy director of Development and Reform Commission to limit the output to the media to explain the reasons.

From the Inner Mongolia Power Grid of information are equally helpless. Zhang Fusheng, general manager of Inner Mongolia Electric Power Company said that the current network access to heating units in Inner Mongolia to reach 12 million kilowatts, after the minimum load power during the night (including the East sent) about 11.8 million kilowatts. In order to meet heating needs, heating unit must be full-fat to run, can not participate in peak shaving, leaving the load of wind power has a very small margin, power grids, wind power can not meet the full requirements of the Internet.

Data shows that at the end of 2009, Inner Mongolia Power Grid has access to wind power installed capacity reached 4.3 million kilowatts, accounting for the maximum power supply load 27.6%, accounting for 34.7% the minimum power supply load, well above the affordability of power in Inner Mongolia (China Electric ASTRI argument, Inner Mongolia, wind power capacity of 8% to 10%).

Obviously, "the Internet is difficult," has restricted the development of wind power industry, a problem.

In January of this year in Beijing, held a special discussion of new energy and power development forum, the State Grid Corporation's initial public response to new energy power generation, "the Internet is difficult" problem. Deputy General Manager of Shu Yinbiao frankly stated at the forum, power grids, to promote a new energy development as a crucial element. He explained that the bottleneck is, wind power, solar and other new energy sources to generate electricity intermittent, random, can be characterized by low scheduling, large-scale access to run after the power grid will have a greater impact of the construction required to increase the peaking power .

On the other hand, China's wind power resources are concentrated in the north-west region and concentrated in the eastern part of the electricity market reverse the distribution of large-scale long-distance transmission problems to be solved. The lack of peak load capacity of electric power system in China long-standing problems, while the large-scale development of new energy to further increase the difficulty of peaking.

There are 10 high-growth in wind power

And wind power, "the Internet is difficult," corresponds to, is wind power industry, the rapid pace of development.

China Renewable Energy Association Wind Energy Professional Committee of Vice-Chairman Shi Pengfei believe that China's wind power installed capacity to double in successive years of growth, based on the next 10 years will be maintained for more than 20% of the fast development momentum.

The rapid development of wind power have to face a reality is that it is confronted with the embarrassment of power grid construction can not keep up.

"All wind farm approved by the state, Grid Corporation of all time and access to power grids, there is no Internet access difficult problem. But in recent years the pace of development of wind power too fast, and far beyond the power grid development plan, which is caused by power-consumptive is an important factor in the difficulties. "State Grid Corporation of India deputy general manager of Shu-biao analysis," China's wind power emerged from the initial development of large-scale, high-concentration of development and long-distance, high-voltage transmission request, showing a model with foreign wind power development significantly different characteristics, and the resulting grid technology and economic issues are particularly prominent, and much more complicated. "

Outgoing corridors to catch up with

The hardship suffered by wind power, has attracted industry attention. They are on different occasions expressed their views and suggestions.

Inner Mongolia Electric Power Company Managing Director Zhang Fusheng that wind energy resources in Inner Mongolia is the country's precious resources, wind power development is not just the responsibility of provinces and regions rich wind power, the need to achieve inter-provincial and trans-regional power grid, including China Southern Power Grid at the national level, the electricity market acceptance of wind power's overall planning, accelerate the establishment of the national electricity market, wind power consumptive mechanisms.

State Grid Corporation of India deputy general manager of Shu-biao that compared with European and American countries, China's wind energy resources are characterized by the distribution of very concentrated, and are at the more remote areas. Therefore, the strengthening of regional connectivity, expanding the scope of consumption is satisfied, it will be in China to promote clean energy such as wind power development in an important way for large-scale. China's large-scale wind power development, we must break through the regional context, the "Three North" area of the wind power delivered to the north, central, eastern load centers throughout the country to achieve wind power-consumptive.
