September 22nd is 100 days before the start of the 14th Five-Year Plan, and the 14th Five-Year Plan of the energy and power industry has reached the final stage. From September 22nd to 23rd, 2020 China Electric Power Development Forum was held in Beijing, with the theme of "Helping the digital transformation of electric power and promoting the high-quality development of the industry", and conducted in-depth exchanges around the hot and difficult issues involved in the development of electric power during the 14th Five-Year Plan. How to give full play to the power of "new infrastructure" and how to transform the energy structure have become the topics discussed by the participants.
Topics such as "Digital New Infrastructure Helps Digital Transformation of Power Grid", "Impact of Large-scale Offshore Wind Power Development on Power Grid and Countermeasures", "Development Opportunities of Energy Storage under the Situation of High-proportion New Energy" and "Development Situation and Practice of Hydrogen Energy Industry" can make people have more predictions on energy and electricity in the Tenth Five-Year Plan.
The "new infrastructure" is full of vitality.
"The era of new infrastructure has begun, and the era of industrial Internet has arrived. The power industry has ushered in a new blue ocean of digital transformation. More flexible, efficient and competitive power grid forms will be the inevitable trend of future development. Digital transformation, intelligent upgrading, and integrated innovation will also become the password to unlock the transformation and upgrading of the energy and power industry. " Xin Yongru, deputy general manager of State Grid Information and Communication Industry Group Corporation, said in his keynote speech at the 2020 China Electric Power Development Forum.
According to Xin Yong, the "new infrastructure" of State Grid Corporation of China involves six other fields except railway and rail transit, among which the construction of new digital infrastructure represented by big data center, industrial Internet, 5G and artificial intelligence (referred to as "digital new infrastructure") is an important part of the new infrastructure. On June 15, State Grid Corporation released ten key construction tasks of "Digital New Infrastructure" to the society, namely, power grid digital platform, energy big data center, power big data application, power Internet of Things, energy industry cloud network, intelligent energy integrated service, energy Internet 5G application, power artificial intelligence application, energy blockchain application and power Beidou application.
"Technological innovation is an important driving force for new digital infrastructure. Considering the key construction tasks of new digital infrastructure of State Grid Corporation of China and the development needs of information and communication industry, and combining with the development trend of strategic science and technology in recent years, we think that chip technology, key technology of 5G+ Beidou, intelligent sensing technology, electric artificial intelligence technology, etc. It will become the key technology to lead the future development and the source power to promote industrial upgrading. " Xin Yong said.
As the core component of new infrastructure in the new energy field, State Grid New Energy Cloud has registered users of1420,000, 9,206 enterprises, with 427,800 visits in August and 6 14 daily visits. Wang Jinsong, deputy director of the State Grid Development Department, said that the construction goal of the State Grid's new energy cloud is to build an international leading new energy digital economy platform with China characteristics, and to establish a new energy open service system of "horizontal collaboration and vertical connection" and "full link, full connection, full coverage, full ecology and full scene".
"The digital economy is an advanced economic form. The digital economy has opened the fission transformation of the traditional industrial economy and has become an important weight for countries in the new round of market competition. " Shen Liang, deputy director of State Grid Big Data Center, pointed out that the characteristics of China's industrial modernization are traditional industry+digitalization, networking and intelligence. Different from the developed countries, China has encountered the opportunity of informatization in the process of industrialization, which determines that the industrialization of China can take the road of informatization without completing industrialization, but the road of deep integration of industrialization and informatization. With the continuous development and improvement of digital technology tools and business models in China and the vigorous promotion of "new infrastructure", the digital economy will become an opportunity for China to overtake the curve in the new round of industrial revolution.
Under the upsurge of new infrastructure, many power companies are exploring and practicing industrial Internet. Fan Weining, general manager of Huaneng Information Technology Company, said that Huaneng Industrial Internet Project is divided into three levels: group side, regional side and power plant side. "Huaneng Industrial Internet has five core points, namely, cloudization of IT infrastructure, providing powerful storage and computing capabilities; Factory equipment data on the cloud, massive industrial data, and mining data value; Business SAAS (providing software services through the network), building an enterprise operation center based on the intermediate platform; Intelligent application as the core and IT as the tool to empower production; Create a win-win situation and create a full-process corporate ecology. " He said.
Charging facilities for electric vehicles are one of the key contents of "new infrastructure". According to Qi Shifeng, deputy general manager of State Grid Electric Vehicle Service Company, in 2025, the charging capacity of special piles in the whole society will reach 42.3 billion kWh, and the charging capacity of public piles will reach 36.5 billion kWh; It is estimated that during the tenth five-year plan period, the total power generation of special piles and public piles in the whole society will be 253.2 billion kWh, and the total power generation of unit piles and special piles in the whole society will be 27.2 billion kWh.
"The interactive market of electric vehicles and power grids has broad prospects," he said. In 2030, the total theoretical potential of the interaction between electric vehicles and power grids will exceed 654.38 billion kilowatts, equivalent to 50 Three Gorges power stations. The total theoretical potential of the interaction between electric vehicles and power grid will exceed 2 trillion kWh, and the total market scale will exceed 654.38+000 billion Yuan according to the estimation of 0.05 Yuan/kWh of the interaction service between electric vehicles and power grid. "It is necessary to strengthen the planning and layout of charging facilities, promote scientific interconnection and orderly interoperability, strengthen charging safety supervision, and enhance sustainability." He suggested.
Huang Yu, director of the Power Planning Center of China Southern Power Grid Energy Development Research Institute, analyzed the difficulties of digitalization of power planning research from practice: in a multi-source heterogeneous data environment, there are many data sources with different calibers, which are often mixed with incomplete, incorrect or irrelevant dirty data; It is difficult to obtain the data of energy industry, and the data of power industry are scattered in various provinces and cities, so it is difficult to collect them by division of labor; At present, some mainstream application software in all aspects of power planning research is relatively independent and has strong encapsulation.
"With the improvement of information technology, more application systems, software and hardware platforms and equipment need to be maintained and managed. How to establish an efficient and collaborative network, a provincial and local collaborative management system, unify management authority, and establish a stable and standardized platform operation and maintenance mechanism has become an important issue in platform information management. " He said.
Energy conversion accelerates stepping on the accelerator.
"Give full play to China's advantages in clean energy, UHV and smart grid. Adhere to the idea of "independent innovation, demonstration first, and China leading", focus on the direction of energy cleanliness, electrification, intelligence and integration, which is related to the overall situation of energy transformation and development, promote the innovation of technology and equipment for energy development, conversion, configuration and use, promote industrial development, and seize the commanding heights of global energy technology. " Li Juan, vice president of the Economic and Technical Research Institute of the Global Energy Internet Development Cooperation Organization, said when talking about the power "14th Five-Year Plan".
She pointed out that the overall path of energy transformation can be divided into three stages. The "14th Five-Year Plan" is incremental substitution, with coal-fired power stepping on the brakes and clean energy stepping on the accelerator, and coal-fired power changing from the main power supply to the regulated power supply, and the new demand is met by wind and light storage and transportation. The proportion of clean energy and power generation installed capacity has been increasing, reaching 57% and 45% respectively. The energy system reached the peak of carbon emissions. From 2025 to 2035, the stock will be replaced, the coal-fired power will be withdrawn, and the transition to regulated power will be accelerated. Clean energy and electric energy will become the largest energy sources at the production end and the consumption end respectively. 2035-2050 is a comprehensive transformation, with China's energy Internet fully completed, coal-fired power transformed into seasonal standby power, and clean energy completely replacing fossil energy.
Nuclear energy, as a "decisive" clean energy, is expected to accelerate its development in the 14 th Five-Year Plan. Qiu Jiangang, vice president of China Electric Power Development Association and president of Nuclear Energy Branch, said that by the end of the 14th Five-Year Plan, the nuclear power units in operation and under construction are expected to reach 90 million kilowatts and1100000 kilowatts respectively. "It is preliminarily predicted that in 2025, the operation scale of nuclear power units will reach more than 70 million kilowatts, accounting for about 3% of the total installed capacity in the country; Nuclear power generation accounts for 6%; Relatively efficient coal-fired power generation can reduce carbon emissions by about 450 million tons per year; The scale under construction is 40 million kilowatts. " "In Central China, where the power load is heavy, the power grid is an important hub for safe operation, and renewable energy resources are scarce and costly, we will strive to start inland nuclear power construction in time during the 14 th Five-Year Plan period." He also said.
Luo Jinhua, deputy director of the strategic planning department of China Huadian Group, shared "the development opportunity of energy storage under the situation of high proportion of new energy". He suggested that we should pay attention to the positioning of energy storage and make a good layout of energy storage in all links; Strengthen industrial support and promote the development of energy storage in various fields; Promote market construction and accelerate the process of energy storage participating in the electricity market; Improve the technical level and promote the high-quality development of the energy storage industry; Improve the standard system and lead the promotion of energy storage technology standards.
Mei Jingyi, chief economist of Guohua Investment Company, a national energy investment group, is very optimistic about the development of hydrogen energy during the Tenth Five-Year Plan period. She pointed out that the global trend of hydrogen energy development has been established and is advancing by leaps and bounds, and domestic hydrogen energy interaction and horizontal competition are becoming more and more frequent. "The China Municipal Government attaches great importance to the development of hydrogen energy, and all localities have formulated plans for the development of hydrogen energy according to their own industrial base and resource endowments. In September this year 16, the five ministries and commissions officially issued the Notice on Developing the Demonstration Application of Fuel Cell Vehicles, proposing that "rewarding instead of supplementing" will effectively promote the formation of the hydrogen energy and fuel cell industry chain. "
But at the same time, Mei Jingyi also pointed out the problems of hydrogen energy: the key technical performance gap of the whole chain of hydrogen energy is obvious, the equipment and key materials depend on imports, the equipment price is high, and the initial investment of hydrogen refueling station is large; Hydrogen production, storage, transportation and filling are short of hydrogen talents, industrial supporting systems and technical standard systems. "It is necessary for the government to clarify market expectations and technical research plans, as well as the national strategy for hydrogen energy development, and form a joint effort of all parties to promote the healthy and sustainable development of the industry." She suggested.
