In the context of optimizing the layout of wind power development, the trend of my country’s wind power development focus shifting to the southern region of the Middle East is more obvious. In 2019, the new installed capacity of wind power in the southern region of the Middle East accounted for more than half. Strong support.
At the recent seminar on wind power development in the south of the Middle East held in Zhengzhou, Henan Province, the participants believed that the development of wind power in the south of the Middle East is promising, but it still faces problems such as a relatively single business model, a “one size fits all” ecological environment protection, and low enthusiasm for local governments. All parties in the industry chain form a joint force to seek breakthroughs.
Low wind speed wind power starts rapid development
Zhu Rong, chief researcher of the National Climate Center, said that the southern region of the Middle East is dominated by low wind speed wind energy resources. The wind speeds in Henan, Shandong, Jiangsu and Anhui increase rapidly with height, but they are still low wind speed resources. According to estimates, China's land-based 80m high and low wind speed wind energy resource technology is 490 million kilowatts, 500 million kilowatts for 100m height, 460 million kilowatts for 120m height, and 410 million kilowatts for 140m height.
In the past two years, with the rise of distributed energy, low-speed wind power has entered a stage of rapid development. The industry believes that if the low wind speed resources in the south of the Middle East are efficiently used, it will be sufficient to support the high-quality development of wind power during the 14th Five-Year Plan.
Li Yonggang, deputy director of the Energy Bureau of Henan Province, pointed out that Henan’s renewable energy power consumption accounted for more than 20% of the total social power consumption, and the cumulative installed wind power capacity reached 8.35 million kilowatts. During the "14th Five-Year Plan" period, how the wind power industry can seize the historic opportunity of a new round of technological and industrial transformation to provide a strong impetus for the green recovery of the world economy after the epidemic is worthy of serious consideration by the wind power industry.
According to reports, there are still some prominent problems in the development of wind power in the southern region of the Middle East. First of all, there are ecological and environmental protection issues, which are the most important factors hindering the development of wind power in the southern region. Secondly, it is the question of how to innovate the business model.
Low wind speed parity needs more targeted technical solutions
The low wind speed and complex terrain in the south of the Middle East have put forward higher requirements for wind energy resource assessment, development and design, unit selection, etc. Its high-quality development cannot be separated from the support of various innovative technologies and applications, and it needs to be targeted. Provide personalized solutions.
At present, the cost of onshore low-wind speed wind farms is about 6,500 yuan/kW. When the annual equivalent utilization hours are 2000-2500, the cost per kilowatt-hour is about 0.29 yuan/kWh. According to industry forecasts, in the future, with innovative technical solutions, the cost of wind farms will be gradually reduced to 4,500 yuan/kW, and the cost of electricity per kilowatt hour is expected to drop to 0.17 yuan/kWh.
Participants judged that according to the current development trend, the single-machine capacity 3.xMW will be the main model in the low wind speed area in the future, and at the same time, the 4.xMW model will quickly occupy a certain market share.
The general manager of a new energy investment company said that with the advent of the era of parity, wind power manufacturers will face greater challenges. It is necessary to continuously improve its own wind power business capabilities in terms of product quality, technical services, and delivery guarantees, and carry out digital transformation. Through asset visibility, revenue visibility, and process visibility, smart wind energy resources, smart design, smart construction, and wisdom The characteristics of the operation and maintenance and smart sharing platform achieve cost reduction and efficiency increase.
Located in the Chaocun-Shenxiandong Decentralized Wind Power Project in Dayu Town, Jiyuan City, Henan Province, it was invested and constructed by a new energy source. A total of 20 SANY heavy energy wind turbines were used to make the wind speed of the exploitable resources reach a record 4.5m/ s. The project started hoisting in July 2019, and was connected to the grid in December 2019 at full capacity. In conjunction with the resource advantages of a certain construction machinery, the construction of the wind farm has been faster and more efficient. Its annual full-flight hours exceed 2000, and the cost of electricity per kilowatt-hour is 5%-10% lower than peers.
Development model business model needs innovation
In the development of wind power in the southern region of the Middle East, decentralized wind power is the main force, but restricted by factors such as a single business model, the value of decentralized wind power has not been fully released in my country, which has affected the development speed of wind power in the southern region of the Middle East.
Zhai Endi, a chief engineer of science and technology, said that compared with the era of subsidies, in the era of parity, there is less room for fault tolerance in projects, and quality needs to be improved in all aspects to ensure "high-quality" income assets.
To achieve high-quality development of low-wind speed wind power, innovation in business models is essential.
Yan Chuntao, the person in charge of a wind power financial business, said that through the "three links" mode of village-to-village, factory-to-factory, and road-to-road links, unified planning, unified development and unified construction can be realized, and decentralized wind power projects can be integrated into centralized wind power projects . This is conducive to further improving the economics of the project; it is convenient to find financing institutions for the project; it is convenient for project development, construction, subsequent operation and maintenance management, and transaction transfer.
According to industry insiders, only innovative technical solutions and a benign and sustainable business model complement each other to truly leverage the low-speed market in the era of parity.
