There are still shortcomings in the hottest new en

  • Detail

At present, China's new energy industry is gradually promoting the revolution of energy production and consumption, and building a clean, low-carbon, safe and efficient energy system has become an urgent need for China's economic and social transformation and development. The development of offshore wind power and photovoltaic power generation is also of great significance to optimize the energy structure and promote energy conservation and emission reduction, which can achieve win-win social and economic benefits. At the same time, in order to achieve higher quality development, the "scenery industry" must also accelerate the intelligent transformation, realize the deep integration of information technology and energy technology, and profoundly change the consumption mode of the Institute of traditional energy production and Endocrinology (Dusseldorf)

promoting the energy revolution is not only an important driving force for the development of human social productivity and civilization progress, but also an inevitable choice to achieve the sustainable development of human society. Recently, under the guidance of China Energy Research Association, the "2018 Yancheng green Smart Energy Conference" jointly sponsored by Yancheng Municipal People's government and vision technology group was held in Yancheng, Jiangsu Province. At the meeting, guests said that it is an inherent requirement of the energy production and consumption revolution and an inevitable trend of the development of green smart energy industry to drive new models, new technologies and new business forms through smart energy, promote the deep integration of Internet, big data and new energy industries, and promote the development of green smart energy industry

the energy industry has "infinite scenery"

on the endless beach along the coast of Dongtai, Jiangsu Province, the tall tower is supported by three huge white blades, "standing" on the choppy waves, with bursts of sea breeze blowing, and the blades rotating leisurely. Under the windmill, patches of blue and purple solar panels are shining. Under the battery board, countless fish and shrimp are also cultivated in thousands of acres of fish ponds

"our photovoltaic power generation project is the largest tidal flat photovoltaic power industry base in the world. It is a renewable energy power generation project encouraged and supported by national policies." Luo Chaozhong, head of the East China integrated management center of cecep solar energy Co., Ltd., said that the installed capacity of the project is 78.8 MW, 2800 mu of tidal flats are used, and 1200 mu of fish farming is used. Since the operation of the project, the photoelectric and aquaculture industries have been creatively combined to form an industrial landscape with photovoltaic power generation on the top and aquaculture on the bottom

Luo Chaozhong revealed that the annual average power supply of the project is about 100million kwh, which can save 36000 tons of standard coal, reduce 27000 tons of carbon dust emissions, reduce 3000 tons of sulfur dioxide emissions, reduce 100000 tons of carbon dioxide emissions, and reduce 1500 tons of nitrogen oxide emissions

"this is an epitome of our 'new energy +' business model." Conghongshen, director of the energy department of Yancheng development and Reform Commission, said that Yancheng is the region with the longest coastline, the widest sea area, the most tidal flats and wetlands, the richest marine resources and the greatest potential for marine economic growth in Jiangsu Province. The wind speed at a height of 70 meters along the Coast and offshore is more than 7 meters/second. It has more than 10000 megawatts of exploitable "scenery resources" and is one of the eight national key wind power bases. "With the help of 'wind power and photovoltaic +' comprehensive utilization mode, we can not only build a national new energy industry base, but also some innovative development and utilization modes can continue to lengthen the new energy industry chain." Conghongshen said

"after the development stages of 'from nothing, from less to more, from low to high, and from inside to outside', the development of Yancheng offshore wind power industry is booming." Dai Yuan, Secretary of Yancheng Municipal Party committee, said that at present, the city has jointly built 6 offshore wind power projects with a total installed capacity of 1.1125 million KW, and 5 are approved to be under construction with a total installed capacity of 1.4 million KW. It is estimated that by the end of this year, the scale of offshore wind power in Yancheng will reach 1.5 million KW, ranking first among all cities in China. By 2020, the installed capacity of Yancheng new energy will reach 11million kW. Among them, the installed capacity of wind power is 7.5 million KW, and the installed capacity of photovoltaic is 3.2 million KW

intelligence promotes green development

"if the new energy industry wants to achieve higher quality development, it must have a smarter brain." Wu Xinxiong, chairman of the China Energy Research Association, said that the current world energy pattern has been profoundly adjusted. With the deep integration of information technology such as IOT, artificial intelligence and big data with energy technology, the new energy model and new business form of intelligence, intelligence, co construction and sharing will profoundly change the traditional mode of energy production and consumption

many domestic wind power giants are "moved by the wind". Jiangsu Goldwind Technology Co., Ltd. took the lead in this step and implemented the first smart micro power demonstration project integrating wind power, photovoltaic, energy storage, smart energy management and other technologies in Jiangsu. It is understood that the total capacity of the project is 2.196 MW, including a 2.0 MW fan, a 100 kW fan and a 96 kW photovoltaic generator, equipped with lead-carbon batteries and the energy efficiency management system independently developed by Goldwind technology

"Smart micro electricity is the most effective technology integration method of distributed energy. It can organically combine the characteristics of distributed power supply, energy storage system, load cooling device: molded plastic extruded layer, which shows high energy density, good recyclability and good cost advantages. After leaving the machine head, it can enhance the interaction with electricity through the energy management system, and can also monitor the power load of users in real time according to the real-time power load of users Through the energy efficiency management system, we can guide the scientific use of electricity, and intelligently and independently adjust the power generation equipment and power transmission and transformation equipment, so as to improve the power quality and power efficiency of users. " The relevant person in charge of Goldwind technology said that now the annual power generation of the project is 4.4 million kwh, and the generated power is supplied to enterprises in the park, with a self use rate of 95%, saving 485200 yuan of electricity expenses for enterprises on average every year

the development of green smart energy industry not only makes enterprises profitable, but also increases farmers' income. Zhu Xiaogang, who lives in Jiangang Town, Dongtai City, now uses electricity for cooking at home from the "micro power plant" on the roof. Zhu Xiaogang told him that two years ago, he invested 78000 yuan to install blue battery panels on the roof of his home, with an installed capacity of 12 kW. While being self-sufficient, he could earn 1300 yuan a month in excess electricity

Zhang Lei, founder and CEO of vision group, believes that the world is undergoing changes in the entire energy system, and a fragmented energy system has begun to accelerate its formation. "The essence of fragmentation is that renewable energy represented by wind power and photovoltaic is reaching a high degree of economy at an unprecedented speed." Zhang Lei revealed that in the future, vision energy will actively build a global smart energy blueprint with the help of IOT, cloud computing, big data, artificial intelligence, intelligent control, intelligent sensing and other technologies, and promote smart changes in the traditional energy field

transformation and development are facing challenges

China Power Development Report 2017 shows that the proportion of non fossil energy consumption in China has increased from 12.1% in 2015 to 13.8% in 2017. In the next three years, China's total energy consumption is expected to continue to grow. In order to highlight the energy structure and jointly promote the partners to go out of the precise and pleasant entrepreneurial trajectory transformation and upgrading requirements in the center of the dial, the 13th five year plan for power development also adds a key principle, that is, by 2020, China's non fossil energy consumption will account for about 15% of primary energy consumption. In this regard, Han Shui, chief engineer of the national energy administration, said that the plan gives priority to the layout of clean energy in the process of power structure optimization. When considering the balance of power and electricity, we should first balance hydropower, wind power, photovoltaic and nuclear power

it is undeniable that there are still many shortcomings in the development of new energy industry, and some problems have been encountered. On the one hand, the subsidy gap continues to expand, directly affecting the healthy and orderly development of the industry. According to the data, by the end of 2017, the cumulative subsidy gap for renewable energy power generation had reached 112.7 billion yuan, and was expanding year by year. At present, it has exceeded 120 billion yuan

on the other hand, the problems of wind and light abandonment are prominent, and there are hidden dangers in overcapacity. Despite the efforts of many parties, the light rejection rate fell to 6% in 2017, but it is still very serious in some places, such as Gansu and Xinjiang, where the light rejection rate reached 20% and 22% respectively. At the same time, the domestic photovoltaic power generation market is growing at a high speed, and photovoltaic manufacturing enterprises have expanded their production capacity. The overcapacity of photovoltaic manufacturing and the quality problems of products and power station construction also appear

"the East is the main load area of energy in China, and the development of energy in the East is also a key step in China's energy transformation." Duxiangwan, former vice president and academician of the Chinese Academy of engineering, believes that at present, the power energy in the Middle East is mainly self-sufficient, supplemented by power transmission from the west to the East. However, some large cities in the East, such as Shanghai and Hangzhou, still rely mainly on electricity from outside, of which coal-fired power accounts for a high proportion. This shows that there is a lot of room for the development of renewable energy in China

Du Xiangwan explained that the world's power system will present four characteristics in the future, namely, high proportion of non fossil power, the combination of centralized and distributed power, multi energy complementarity, and the combination of energy storage and intelligent control. "With the planning and promotion of relevant government departments, it is inevitable that the proportion of renewable energy will increase and the proportion of coal-fired power will decrease." Du Xiangwan believes that the development of high-quality and high-proportion non petrochemical energy is the direction of China's and even the global energy transformation, and is the strategic commanding point that countries compete for. According to the energy production and consumption revolution strategy (2016-2030), the proportion of non fossil energy in China will increase to 20% by 2030
