Photovoltaic wind power policies focus on innovation and development are the key

Recently, the industry’s long-awaited “Twelfth Five-Year” National Strategic Emerging Industries Development Plan has finally been introduced, proposing that by 2015, the proportion of new energy in total energy consumption will increase to 4.5%, and the annual CO2 emission reduction will be 400 million. More than tons. The accumulated grid-connected wind power installed capacity exceeds 100 million kilowatts, the annual power generation capacity reaches 190 billion kilowatt-hours, the installed capacity of solar power generation reaches more than 21 million kilowatts, and the photovoltaic power generation system achieves the same price on the user side. The installation area of ​​solar thermal utilization reaches 400 million square meters. Biomass power generation capacity reached 13 million kilowatts.

“The earliest announced 2015 solar installation target was 5 million kilowatts, which was later adjusted to 10 million kilowatts and further increased to 15 million kilowatts. Until now, the “12th Five-Year Plan” national strategic emerging industries development plan has determined 21 million kilowatts, Among them, 20 million kilowatts of photovoltaics and 1 million kilowatts of photovoltaic power generation clearly demonstrate the country’s attitude of intensifying efforts to cultivate the solar energy installation market.” Meng Xianji, deputy director of the China Renewable Energy Society, told reporters: “Different from solar energy, domestic The wind power installation market will develop steadily under the premise of ensuring the quality of the grid connection. Inner Mongolia and other places will first solve the grid connection problem, and more new wind power installations will be located in the southeast coastal areas."

Accelerating the cultivation of the domestic photovoltaic market Since last year, the global solar energy industry has fallen into an increasingly severe "winter". According to the survey, more than half of the small and medium-sized battery module companies in the country have stopped production, and 30% have cut production significantly; a number of polysilicon companies have cut production and stopped production. When this happens, the quietly opened domestic market will be like snow.

"The 12th Five-Year Plan for National Strategic Emerging Industries Development" clearly stated that it mastered key technologies for solar power generation and heat utilization, significantly increased the R&D and manufacturing capabilities of solar energy utilization equipment and new materials, and conducted demonstration and demonstration of solar thermal power generation, establishing an international presence. The advanced level solar energy industry system has significantly increased the “12th Five-Year Plan” solar installation target from 5 million kilowatts to 21 million kilowatts.

According to the statistics of the photovoltaic industry alliance under the Ministry of Industry and Information Technology, the total installed capacity of photovoltaic power generation in China was 2.70 million kilowatts in 2011, a year-on-year increase of more than 400%, making it the third largest photovoltaic market in the world. Last year, the National Development and Reform Commission promulgated and implemented a feed-in tariff subsidy policy for photovoltaic power generation, which further accelerated the development of the domestic photovoltaic market. The market is generally expected that the new installed capacity in 2012 will reach 5 million -7 million kilowatts.

"These two years have already added up to almost 8 million kilowatts. If we calculate at 21 million kilowatts, there will be almost 5 million kilowatts of growth every year for the next three years, so this goal is reasonable and even conservative." Reporter: “But this is only a national planned installation target. Because of the national grid-connected policy and economic subsidy policy support, the enthusiasm for the construction of photovoltaic power stations is very high. In some places, even the power station is built up first and then go online and go through the formalities. , so the actual installed capacity will be far more than 21 million kilowatts."

"The country has repeatedly increased its solar installation target, which is related to the country's huge production capacity of photovoltaic modules. Such a large production capacity has squeezed out foreign PV module giants, and it is not backward production capacity. At present, domestic PV companies have been greatly affected in the international market. The restrictions are bound to give them a way out in China,” said Meng Xianjun.

"This is a very good thing. In the past, our country's photovoltaic industry has always depended on technology being dependent on foreign countries and products relying on exports. This two-out-of-the-box processing model is very unsafe. Once trade frictions occur, there is no way to fight back. In this situation, it is necessary to strengthen independent innovation, increase core competitiveness, cultivate the domestic market, and increase resilience. However, independent innovation is not easy, which takes time, so fostering the domestic market is more realistic and effective.” Meng Xianzhe said. “However, our attitude in the domestic solar installation market is to nurture, that is, to develop in a step-by-step, planned way. Whenever a country is building a photovoltaic power plant, it should follow the national planning objectives, otherwise there may be an increase in wind power outbreaks. On-grid issues."

How to develop the domestic photovoltaic manufacturing industry when the global photovoltaic market is sluggish? The person in charge of Changzhou High-tech Zone told reporters that Changzhou Hi-tech Zone will focus on the production of crystalline silicon solar modules from Trina Solar, improve industrial chain support, and selectively promote the system integration and power plant operation services in the downstream of the photovoltaic industry chain. Projects, and pay attention to the new development trend of photovoltaic industry, actively introduce thin film solar cells and new technology projects, and strive to re-introduce 1-2 well-known photovoltaic companies at home and abroad to build a large-scale photovoltaic industry park. By 2013, Changzhou High-tech District Photovoltaic Industrial Park will complete 8 major projects including 3 million kilowatts of high-efficiency solar cells and photovoltaic modules and photovoltaic national key laboratories of Trina Solar, achieving a total investment of 20.85 billion yuan and a sales revenue of 50 billion yuan. Yuan above.

Quality First Orderly Development of Wind Power As of the end of June this year, China's grid-connected wind power installed capacity reached 52.58 million kilowatts, surpassing the US to rank first in the world.

Since 2006, China's newly installed wind power capacity has reached 50 million kilowatts, achieving a huge leap in wind power from 2 million kilowatts to 50 million kilowatts, and over the past 15 years of wind power development in the United States and Europe. At present, the wind power installed capacity in eastern Inner Mongolia, western Inner Mongolia, Jiuquan in Gansu, and northern Hebei accounted for 22%, 21%, 20%, and 16%, respectively, which is equivalent to 17% in Germany and 21% in Spain.

However, while China's wind power has been greatly developed, grid-connected conditions have not been optimistic.

According to data from the State Electricity Regulatory Commission, wind power from wind farms in the “Three North” region reached 12.3 billion kWh in 2011, and the rate of wind rejection was 16%. The rate of wind curtailment was further expanded in the first quarter of this year. “The emergence of this issue is related to the characteristics of volatility in wind power, but also to the uncoordinated development of wind power and other power sources and grids, and the inability of the power management system to adapt to the characteristics of wind power,” the National Energy Administration explained.

“At present, in areas with serious grid connection problems, such as Inner Mongolia, new fans are installed. The main problem is to resolve the problem of no grid connection or wind disposal before. The new wind power project focuses on the southeastern coastal areas near the users.” Told reporters.

"Last year, China's total installed capacity of wind power was the world's largest, but the amount of grid connection was less than that of the United States. The amount of on-grid electricity is much lower than expected. This shows that our wind power efficiency is not high enough." Meng Xianzhang said: "The stage of explosive development of wind power It has already passed and the future development model will be to ensure quality, increase efficiency, and develop in an orderly manner."

In order to solve the problem of wind power grid integration, the “Twelfth Five-Year National Strategic Emerging Industries Development Plan” specifically proposed major actions and major policies: the establishment of wind farm power forecasting and forecasting system, and the significant improvement of wind power concentrated development of regional power grid operation to absorb wind power. Proportion; built a large-scale wind power supporting external transmission channel to solve the problem of long-distance transmission of wind power; implementation of renewable energy power quota system, build a power grid operation and management system to meet the development of wind power; accelerate the construction of a smart grid to adapt to the development of new energy and Operating system.

Models and technologies need to innovate to meet grid-connected pressures on large-scale centralized power plants. Flexible and efficient distribution may become a breakthrough for new energy sources in terms of institutional mechanisms.

Shi Lishan, deputy director of the New Energy and Renewable Energy Division of the National Energy Administration, recently stated that the construction of large-scale power plants does not have much technological content and lacks institutional innovation. In the near term, large-scale construction of large-scale power plants should not be the main focus. It is necessary to open up the user-end market and support users to build their own photovoltaic systems.

Regarding the prospects of the domestic distributed photovoltaic market, Li Junfeng, director of the National Center for Climate Change Strategic Research and International Cooperation, recently stated that by 2015, only one distributed solar photovoltaic power generation capacity will exceed 10 million kilowatts.

Distributed new energy is the innovation of the development model, and the ability of independent innovation in technology is the foundation of the sustainable development of the new energy industry. The “Twelfth Five-Year National Strategic Emerging Industries Development Plan” proposed that during the “Twelfth Five-Year Plan” period, the ability to integrate and transform major scientific and technological achievements of enterprises should be substantially improved, and a group of key core technologies with dominant position should be mastered. The international advanced level of innovation platform, the level of invention patent quality quantity and technical standards have been greatly increased, and the proportion of R&D input of key emerging enterprises in strategic emerging industries accounts for more than 5% of sales revenue. A number of key core technologies have reached the international advanced level.

"The "planning" shows that the state attaches great importance to strengthening independent innovation and improving its core competitiveness, and is making efforts with steps, goals, and down-to-earth efforts. This is very positive." Meng Xianyi said: "But this process will For a long time, within the 12th Five-Year Plan period, we should be able to establish a basic research platform in all aspects of the industry chain, and make breakthroughs in certain key links. To truly have a certain level of complete independent innovation capability, it may be necessary to 2020.
