Breakthroughs in the Potential of Wind Power Bottlenecks

In 2012, the perception of newly installed wind power data was not very good. From the perspective of personal experience, the wind power industry has indeed entered a bottleneck period. For this reason, at the Shanghai Wind Energy Exhibition held recently, some experts emphasized that “the obstruction of wind power development is not caused by a single cause, but rather a systemic problem and there are problems in almost every link”, which is intended to emphasize that people in the industry should share Concerned about the possible breakthroughs in the current wind power situation, providing advice and suggestions for the development of wind power in China.

A careful analysis of the speeches made by experts at the meeting revealed a series of bottlenecks that hinder the development of wind power.

After the revision of the "Renewable Energy Law," the concept of "full-scale guaranteed acquisition" is unclear, and the macroscopic level of the acquisition of renewable energy causes the objective impact of "public opinion, public reasoning, and poetry that is reasonable". In addition, at the current speed of development of wind power, it is still difficult to accomplish the goal of wind power development in the “Twelfth Five-Year Plan”. Straightening out various types of contradictions and optimizing development ideas are the main means to achieve this goal. In addition, the amount of wind-discharging in 2012 was significantly higher than that in 2011. From the trend point of view, if no measures are taken, the scope and degree of wind-reduction will most likely further expand. At the same time, on the premise that the equipment market is becoming saturated, more manufacturers will place their hopes on overseas, but what is different from the internal environment is how to bypass trade barriers and obtain approval from overseas markets. This is a relatively tricky business. . The development of offshore wind power exposes many issues such as lack of policy experience, project development due to excessive approval processes, and stagnation. As a result, the development of offshore wind power, which has been hailed as a new opportunity, has been repeatedly constrained and progress has not been smooth.

Although these issues have received varying degrees of attention from all parties, the priorities of the so-called priorities and the direction and level of the reform have been preceded and delayed. At present, the improvement programs that are highly concerned and have been making progress are mainly aimed at solving problems such as offshore wind power, wind curtailment, and quota systems.

Since 2010, more than two years have passed since the bidding for offshore wind power concessions, but the project has still not been approved and is lagging behind the original plan. In contrast, the construction of some offshore demonstration wind farms and offshore experimental wind farms has been relatively smooth. The development of the intertidal zone project is in full swing. Excluding the Shanghai Donghai Bridge offshore wind farm, these offshore wind farms have completed the installation 182 last year. MW. However, these developments cannot be compared with the scale of the concession project, which inevitably makes the industry very disappointed with the development of offshore wind power.

However, these concessions are not stalled. Experts at the show revealed that the maritime concession project has made some progress and is likely to be approved in 2013. It seems that the market situation of large-capacity offshore wind turbines being brought together by the whole machine manufacturer is slightly out of the blue, and there is still the potential for upward breakthroughs under the floating ice of offshore wind power.

How to solve the issue of increasingly severe wind curtailment, the government, the industry, and even the enterprises have done a lot of work and are currently advancing the work, mainly including wind and fire replacement and construction of access roads.

It is difficult to deny that one of the main causes of the problem of disqualification is the distribution of benefits. In some areas of China, not only wind energy resources are good, but also coal resources are abundant, but it is far from the power load center. The transmission capacity of the power grid is difficult to meet the capacity of coal-fired power and wind power with large capacity. In order to reduce discarded winds, the Northeast Electricity Regulatory Bureau conducted a series of experiments on "replacement of wind and fire" in the Mengdong area. Through wind power companies, they compensated the coal-fired power companies that suffered losses due to the reduction of wind and wind, thus balancing wind power and thermal power. Benefits to solve the wind problem.

But this is more like an expedient measure. In spite of the fact that the thermal power plant may continue to increase its installed capacity after being compensated, wind power compensation will gradually become unsustainable, and it may not be justified in legal terms. As a basic national policy, energy conservation and emission reduction are China's unquestionable and resolutely abide by principles. The "Renewable Energy Law" clearly stipulates that the state encourages and supports renewable energy power generation instead of fossil energy. Although wind energy has almost no cost as an inexhaustible source of energy, the current investment in equipment for wind power generation, operation and maintenance costs are not low, and the resulting cost of electricity is still higher than thermal power. Therefore, it is counter-productive to make unprofitable wind power pay for profitable power purchases. Moreover, the cost of pollution from fossil energy power generation has been completely ignored, which is unfair to developing wind power.

As a result, Shi Pengfei, deputy director of the Wind Energy Professional Committee of the China Renewable Energy Society, proposed at the exhibition that China should integrate wind power into the overall planning of the power system, and comprehensively plan power supply, grid, energy storage, and load allocation, and bundle thermal power, hydropower, and wind power. Delivery, using pumped storage and natural gas as the peaking power supply, and at the same time introducing a scheduling forecast for high power output.

In addition to the dispute over interests, the biggest bottleneck faced by the problem of disqualification is the lack of access to construction.

According to experts at the meeting, China is strengthening the study of the smart grid's consumption and transportation technologies for large-scale wind power. It plans to open a special UHV exchange between Changsha and Mengxi to Changsha in 2013, Ningdong to Zhejiang and Ximen to Taizhou and Mengxi. There are 4 UHV DC transmission lines in Hubei that can effectively alleviate the problem of wind power transmission. At present, the State Grid has begun construction of a ±800 kV UHV transmission line from Hami South to Zhengzhou, Xinjiang. It is reported that this project will leave 3 million kilowatts of power channels for wind power, and some experts suggest that wind power should account for 70% of its total transmission capacity. . In any case, transporting wind power is an important task for this 2210-kilometer transmission line and should not be interpreted as "wind power". This project, which is expected to be completed in 2014, also marks the speeding up of construction of China's UHV lines.

Another point of concern at this exhibition was that it has been "still holding a cover" and was defined as a "selected machine" quota system.

Ren Dongming, director of the National Renewable Energy Center, elaborated on the formulation of this policy. According to the briefing, the National Energy Administration began drafting a quota management system in March 2010. In September 2011, the "first draft of the management of renewable energy power quotas" was completed. After being revised and improved, the National Energy Administration in 2012 On the 26th of the month, a notice on the request for comments on the management of renewable energy quotas was issued.

As of now, relevant parties have feedback, and the policy development department is weighing the research proposals. However, this process is also a step that most experts are most concerned about.

Since the quota system, to a large extent, makes renewable energy the type of energy that is compulsorily used in the national energy utilization system, it will more or less violate the interests of power generation companies that use traditional energy to generate electricity for their main business. On the contrary, this policy will also play an active role in the development of enterprises that attach importance to the development of renewable energy. Just like a lever that can be adjusted, the quota system can enable power generation companies to use conventional energy to generate electricity while failing to evade corporate social responsibility. Therefore, in addition to many voices suggesting that allowance trading be allowed, there are some voices suggesting that quotas in developed regions be raised, or that quotas for areas that are not rich in resources be reduced. There are even some provinces and cities, including developed regions, who are unwilling to assume quotas.

In short, from the present perspective, many of the proposed ideas are still difficult to elute and arrogate self-interest suspicion, prompting the contradictions to remain prominent. Although the introduction of the quota system is in full swing, there is still a lot of work that needs to be coordinated. Policy-makers must hold high the low-carbon, environmentally-friendly national policy, which is a "Shang Fang Bao Jian," and continue to explore the wisdom of governance.

From a microscopic point of view, the game between interests and responsibilities is bound to cry, but from a long-term perspective of low-carbon development and green economy, everyone will be the beneficiaries of renewable energy. After all, We breathe the same air.
