Current our country is in key period of economic and social transformation, which is the construction of ecological civilization, promote the crucial stage of energy revolution, renewable energy is energy from alternative sources of energy into main force.Wind power as the largest and the most mature technology development of renewable energy, in addition to natural green attributes, the resources endowment, capital cost, etc also have to compete with conventional energy power.Many countries have put the wind as improving energy structure, the important choice to respond to climate change.


"Twelfth five-year" period, China's wind power capacity has become the world's first, and was finished ahead of planning goals.Longyuan power group co., LTD., as the earliest professional engaged in the development of wind power company, the current wind power in the world's first, is expected by the end of this year is expected to exceed 20 million kw.Longyuan power as a leader, witnessed the development of China's wind power more than 20 years, witnessed the stages of the maturity of the wind power industry, also for the healthy development of wind power industry during the period of "much starker choices-and graver consequences-in" have more in-depth thinking.

"Have to" and "lost"

Review longyuan wind power development course, summarized from the technical level, there are three main experience: first, grasp the development opportunities, established the first mover advantage;Second, insist on innovation and development, the following industry technology progress;Third, the pursue benefit maximization, counted out project benefit.

2009 years ago and put into production of wind power projects established the leading position of longyuan wind power, create value at the time, established the longyuan advantages in the field of wind power in China.In the view of the development of the project as a mainstay of the once very good completed its historic mission.But as the "three norths" electricity situation deteriorating, project profit margins before 2009, is the objective reality, the common problem facing most wind investors.Due to the unit performance is poorer, coupled with early micro location technology level is low and drafting know enough for large wind farms, the estimate is insufficient, part of the project benefit has value, reach the feasible design project in the red.Must be adhered to in the future to pursue higher benefits of wind power technology innovation to drive development, blindly rely on hold old projects for state subsidies is a non-starter.

Avoid industry again detours

Wind power industry in our country since the renewable energy law promulgated has been more than a decade of booming development, standing on the national energy conservation and emissions reduction of the height of the review of the history of the renewable energy development, the result is for sure, but walking detours and also painful lesson, some problem today is not very good research and solve.In the final analysis, the root of the problem is the "impotence", not to carry out the responsibility, the parties involved only immediate interests, arbitrary encroach on the rights of the renewable energy, disturbed the market order of renewable energy, which is certainly worth the parties think seriously.

1. Impotence, the renewable energy law implementation

"Renewable energy law is guarantee basic solution of the renewable energy development in China, it is also the basis for the evaluation of renewable energy and purpose.Requirements clearly in the law, "the power grid enterprise shall buy all the renewable energy grid-connected power generation project within range of the grid power of using the Internet, and provide Internet service for renewable energy generation. Not full acquisition of renewable energy electricity, thereby causing loss to the renewable energy power generation enterprise economy, shall be liable for compensation, and by the state electricity regulatory institution shall order correction within a time limit; refused to correct and impose a renewable energy power generation enterprise economic losses under double penalty".But related parties to meet interests contradiction is habitually sacrifice renewable energy, the energy conservation and emissions reduction aside, blatant impotence, some problem is far from technology level, is the management problems of coordination.

Inadequate in the face of the current national renewable energy subsidies, abandon the wind power rationing, and so on and so forth, some government departments on the one hand, in order to increase the proportion of renewable energy power generation, hide abandon the wind electricity problems, forcing enterprises to participate in power on trading, its essence is to use the national renewable energy special funds to solve local economic development and the problems existing in the management mechanism.Subsidies to solve insufficient funds on the other hand, one-sided emphasis on renewable energy costs down space again big, the wind high corporate profits, pushing parity on the Internet, ignore the meaning of emissions reduction.At the same time because of many historical debt problem has not been solved, and mixed together with many of the new policy, there is no separate studies, it was originally as long as our renewable energy career normal do things according to the institutional and legal, falling into "headache cure head, feet hurt the medical foot" of the cycle, not only for enterprise to evaluate project returns, more heavy burden.Longyuan wind power in gansu, xinjiang has decision-making errors, exceptional project after the production of the power brownouts, far can not meet the design value, this is we the cause of the electricity market research is not enough, but the main reason is we promise too believe that the local government and power grid.

The competent department of energy industry rules, more should actively promote the implementation of the renewable energy law.

Part 2. Wind power manufacturers get rich quick, penny wise and pound foolish, do not attach importance to technological progress

Wind power development in the early some wind turbines manufacturing enterprise self-discipline consciousness, use in the local construction assembly factory occupy wind resources and exaggerated perfection, eager, and through the local government forced into the local wind power development enterprise USES the local equipment, causing unnecessary redundant construction, disrupted the market order.Such as before in jilin tongyu, jiuquan expansion of the construction of the wind power plant are basic in the shutdown state.Looking back on it, enterprise, government, neither party is manufacturers have benefits.

Part 3. Wind power developers cut-throat competition, make quotation, destroy the market order

Wind power development enterprises is the main body to promote the development of wind power scale, but large difference of development investment main body and development ability, development disorder problem is objective existence.Most wind power development enterprise development speed and construction scale, light output level, operation management and profitability, and even some state-owned wind power developers short-sighted, blind arbitrary to local government promised all sorts of conditions, "investment enterprises, to find supporting industries, kenda floor center", finally some, though not to cash, but add to the local government issued many restrictions on wind power developers constraints, such practices destroys the normal wind power investment development environment.

4. Grid follow conservative ideas, not take the initiative to adapt to the rapid development of renewable energy

Also the current power grid with emphasis on the randomness of renewable energy sources such as wind power brings difficulties to scheduling, not according to the characteristics of renewable energy power generation, improve scheduling techniques, perfect the relevant specification, caused a lot of restrictions to renewable energy grid given.In China only 5% of the water under the condition of renewable energy electricity has been more than 20% of the electricity loss, compared with the advanced countries the gap is very big, contrary to the purpose of the national development of renewable energy, also does not conform to the power grid in China as the world's largest power grid dispatching operation level.

Europe has advanced, real-time electric power demand side management (technology) as well as the balance between supply and demand system energy efficiency technology, a few times in the average wind power, photovoltaic power in China, still can hardly limited electricity.Power grid operation of the organization, these countries are in-depth study and combined with its own market rules, make full use of the statistical law of new energy output characteristics, also use the fact proved that, even if they don't rely on energy storage, such as technological breakthroughs in the future, also can realize substantial new energy alternative.Our grid is still continue to use the old system, the old way, lead to cannot fundamentally solve the new problems.

In the end, the future of renewable energy will commit trillions, stable, long-term, faithful policy environment is the precondition for the healthy development, the pursuit of technological progress, speed up innovation is to maintain the sustainable development of our way to win.

Innovation driven health sustainable development

1. The low wind speed distributed development will be the important supplement of the future wind power development, the premise to build corresponding system and mode

In the south and coastal regions development low wind speed distributed wind power, there are formalities for examination and approval of environmental protection, land use planning and complex problems.Only solve the land owners, residents and local governments at all levels and other stakeholders, let stakeholders benefit from wind power development, distributed wind power development is possible.If you want to solve problems in distributed wind the whole industry chain and service system, involving ecological farmland use, examination and approval, access, electricity, settlement institutions and mechanisms and technical support.

2. Wind power technology development to the development of a wind power resource endowment conditions

Through the technological innovation of recent years, the fan impeller diameter increased, to promote the efficiency of airfoil, control strategy of intelligent technology, greatly improved the overall efficiency of the unit.The breakthrough of IEC standard of personalized fan, personalized wind constantly emerging, to set model transformation model to adapt to even resources has become a wind power to develop a new development direction.According to statistics, the domestic mainstream wind model unit kw of area swept every 2 years increased by 13% - 14%, capacity can be increased by 7% - 9%.

The mainstream fan factories fan load, with the help of a high precision simulation optimization and control of construction cost by new material, new technology, has made a lot of plain type wind field is not a big increase in cost can be widely used in tower under the condition of technology solutions.Hub height of 140 meters to the current domestic flexible tower drum has been in practical application, further expand the development space of the wind.

3. The technical progress will eventually promote wind power with fossil energy equal competition ability

Recently, the national energy bureau issued a "notice about wind power parity Internet demonstration work, puts forward try to wind power to participate in the parity on the Internet, and to ensure parity wind unlimited power of the Internet.To be sure, with the constant progress of wind power technology, the unit electricity cost decrease, affordable Internet access is possible in the long term, wind power will eventually have the ability to compete with conventional fossil energy equal, this is the trend of The Times.

But because the wind and the role that fossil energy in emissions is different, the value of what they play is not comparable.The state shall implement a wind power electricity price subsidies, it is because of wind power can replace fossil energy, create additional green value, is to use the least amount of renewable energy fund subsidies maximum wind power, strengthen the competitiveness of wind power, real good make more high quality electricity, really achieve the result of reduction.The root of the problem is that the relevant government departments management mechanism and interest distribution, relevant departments should not only set goals, but also have specific technical support and management measures to publish to the society transparent renewable energy scheduling information.

4. The uhv did not meet the design expectations, to be delivered to the outside to improve optimization space is large

To solve the problem of wind power given, the grid will put forward the construction of uhv line outside the wind and fire after send, practice shows that due to reasons such as technology, economy, uhv outside to send new energy did not achieve the desired effect.Of nonaqueous renewable energy transmission in 2016 only 14.5% of 5 uhv line transmission capacity.In 2016 through the hami - zhengzhou outside dc supply electricity project for the actual average power only 1550 hours, up to 30.8% power rationing, far can not meet the design value.XiMeng - shandong line, in August 2016 was put into operation in 2016 renewable energy transmission ratio is almost zero.The old problem is not solved, during the period of "much starker choices-and graver consequences-in", will still have the stake - tianjin south, jiuquan - hunan, XiMeng - jiangsu taizhou, ZhunDong - east China routes will be put into operation, there are several routes in planning, most of these lines ziqi wind left light seriously, can you send the renewable energy health, relevant departments need to careful analysis research, truly "who promises, who is responsible for".

The power surplus stage in our country, promoting the construction of uhv if early too quickly, will inevitably cause the preemption of resources, if thermal power to preempt the pretext of nimble uhv resources, so will lead to more coal unit is locked, will only make the "capacity" harder, virtually deviated from the general direction of China's energy structure adjustment, tied up the wind power, the development of thermal power, which increases emissions.

Energy conservation and emissions reduction is common cause of mankind, is also the inevitable choice of our government.Really play a role of wind power the main alternative energy, and needs more efforts to pay, all parties in society, the sacrifice of more immediate interests.Social parties to actively guide public opinion, strengthen the wind power in the importance of energy saving and emission reduction, the government should establish different from unilateral pursue GDP development and assessment system of green development and green assessment mechanism, to carry out the real action to reduce emissions, really.
