Analysis on the development ideas of China's wind power industry avoid the great leap forward recently, the National Energy Administration issued the notice on strengthening the requirements of wind power consolidation and consumption, which proposed that the consolidation of wind power would be an important reference index for the layout of new projects, and areas with significantly low wind power utilization hours should not further expand the construction scale. Meng Xiangan, vice president of China Renewable Energy Association, told China United Business Daily that this shows that the country's development of wind power has shifted from pursuing the installed capacity in the past to paying more attention to the quality of wind power development and power generation efficiency

great leap forward

China's wind power industry has been developing slowly in the past 20 years. In 1995, the country proposed the goal of achieving 1million kW of wind power installed capacity by 2000, but only 764000 kW was completed until 2004. In 2005, the state passed the renewable energy law, which puts forward the requirements of compulsory, full guaranteed acquisition, classified electricity price and full sharing of renewable energy power generation. The wind power industry with various preferential policies such as electricity price subsidies has quickly become an investment field with low investment threshold and strong profitability. Subsequently, the national development and reform commission delegated the approval authority of the previous 50000 kilowatt scale projects to local governments. As a result, investment enthusiasm was high in all regions, and wind power projects below 50000 kilowatts were springing up everywhere

in 2005, the country released the wind energy index plan of the eleventh five year plan, and put forward the installed capacity target of 10million kW by 2010. As a result, this goal was achieved two years ahead of schedule in 2008

in 2010, the global wind power industry suffered from the impact of the economic crisis in Europe and the United States. After five years of explosive growth, the growth rate of new capacity was only 3.1%, down 40 percentage points from the previous year. In 2010, China's new installed capacity of wind power reached 18.927 million KW, with a cumulative installed capacity of 44.733 million KW, surpassing the United States and ranking first in the world

in 2011, according to the statistics of the wind energy professional committee of the China Renewable Energy Society, last year, the mainland of China added 11409 new wind turbines with an installed capacity of 17630.9mw, and 45894 wind turbines were installed in total with an installed capacity of 62364.2mw, an annual increase of 39.4%, and the growth rate was half that of 2010. Due to the rapid development of China's wind power industry, the problems of wind power consolidation, equipment quality, wind farm operation and management are becoming increasingly serious. The high-speed momentum of the wind power industry suddenly cooled in 2011

at the two sessions of the National People's Congress this year, the manuscript of the government work report specifically mentioned stopping the blind expansion of solar energy, wind power and other industries. China's wind power industry has grown from a global leader overnight to be characterized as blind expansion, which is in urgent need of stopping. Last year, China's wind power generation was about 97.1 billion kwh last year, accounting for only 1.56% of the total power generation, accounting for a small proportion in the country's entire energy structure. However, due to the phenomenon of wind abandonment, a total of 17million kW of installed capacity was idle last year, which is equivalent to the new installed capacity of wind power in the country last year. According to incomplete statistics, last year, 10billion kwh of wind power was lost due to power rationing, and the direct economic loss reached nearly 10 billion yuan. A record high

Shi Pengfei, vice president of the wind energy professional committee of the China Renewable Energy Society, told China United Business Daily that one of the main reasons for wind abandonment is that the speed of power construction cannot keep up with the rapid development of China's wind power industry

reform

Shi Pengfei believes that in the past, when China's wind power development was not fast, the country developed China's wind power industry with the idea of building a large base and integrating large power. Because the large base and the power load center are not in the same place, it is necessary to realize large-scale, high concentration, high voltage and long-distance transmission of electricity

at present, wind power is uncontrollable and cannot be stored, which brings difficulties to peak load regulation, frequency regulation and voltage regulation, and ensuring power safety. Because the wind turbine does not have the ability of low-voltage ride through, more than 200 wind turbine disconnection accidents have occurred in China in the past two years. The country cannot establish intelligent AC UHV electrolysis in the short term to solve the problem of wind power consumption and safety, so the phenomenon of wind abandonment is inevitable

for this reason, the technical regulations on wind farm access to power system, which has been implemented since June 1, has made clear requirements for wind power active power and its control, reactive power standard and its control, low voltage ride through capability, wind farm fan detection, etc. This provides a strong support for solving the problem of electrical safety

for the phenomenon of wind abandonment in various places, the National Energy Administration recently issued the notice on strengthening the requirements of wind power and consumption work (hereinafter referred to as the notice), which clearly proposed that the best and most designed scheme of wind power should be provided to automobile manufacturers and the situation should be taken as an important reference index for the layout of new projects. Areas with significantly low utilization hours of wind power should not further expand the construction scale

previously, the National Energy Administration issued the notice on the relevant requirements for regulating the management of wind power development and construction, requiring all regions to focus on cleaning up unplanned projects, and strictly control the shangmaxin project of wind power bases with a waste air volume of more than 20%

in the future, the national energy administration will promote wind power enterprises to do a good job in wind energy resource evaluation, wind farm site selection, equipment selection, etc. on the premise of paying attention to and conditions demonstration and power market research, and deepen the feasibility study of wind farm construction. Power enterprises are also required to scientifically arrange the operation of wind farms, take technical measures to ensure the parallel operation of wind power concession projects and the full acquisition of generated power, and shall not limit the output of concession projects and demonstration projects approved by the National Energy Authority. By reasonably arranging the construction schedule of the project and coordinating the construction of wind power and electricity,

in the future, China's wind power industry will change the past idea of building large bases and integrating into the development of large power. Meng Xiangan believes that due to the characteristics of wind power, China will focus on the development of distributed energy systems in the future, close to the power load center. We should pay equal attention to centralization and decentralization, continue to build 10 million kW wind power bases, and encourage decentralized construction of small and medium-sized wind power projects outside these large bases according to local conditions, using existing transmission lines. Develop low wind speed wind farms and encourage decentralized access to electricity

for this reason, the technical regulations on wind farm access to power system, which has been implemented since June 1, has made clear requirements for wind power active power and its control, reactive power standard and its control, low voltage ride through capability, wind farm fan detection, etc. This provides a strong support for solving the problem of electrical safety

It can also decide whether to add colors, plasticizers, conductive materials or other materials, requiring power enterprises to scientifically arrange the operation of wind farms, take technical measures to ensure the parallel operation of wind power concession projects and the full acquisition of generated power, and shall not limit the output of concession projects and demonstration projects approved by the National Energy Authority.

The technological complexity of developing low wind speed wind farms, encouraging decentralized connection and production of ABS, and the investment in the construction of ABS projects are the largest projects in the aluminum processing industry
