How to start and how to transform the energy structure has become the topic of much discussion among the delegates.

"Digital new infrastructure to help the digital transformation of the grid", "large-scale offshore wind power development on the impact of the grid and countermeasures", "a high proportion of new energy scenarios under the development opportunities of energy storage ", "Hydrogen industry development situation and practice" ...... These topics allow people to "14th Five-Year Plan" energy power can have more foreknowledge.

"New infrastructure" contains vitality

"The era of new infrastructure has opened, the era of the industrial Internet has arrived, the power industry has ushered in a new blue ocean of digital change, more flexible, more efficient, more competitive power grid form will be the future. competitive grid form will be the inevitable trend of future development, digital transformation, intelligent upgrading, integration and innovation will also become the code to unlock the transformation and upgrading of the energy and power industry." In the 2020 China Power Development Forum to make a keynote speech, the State Grid Information and Communication Industry Group Corporation, deputy general manager Xin Yong said so.

According to Xin Yong, State Grid's "new infrastructure" involves the remaining six fields except for railroads and rail transportation, of which the construction of new digital infrastructure (referred to as "digital new infrastructure"), represented by big data centers, industrial Internet, 5G, artificial intelligence, etc., is the new infrastructure. "On June 15, State Grid Corporation released to the community the "digital new infrastructure" ten key construction tasks, respectively, the grid digital platform, energy big data center, electric power big data applications, electric power Internet of Things, energy industrial cloud network, intelligent energy integrated services, Energy Internet 5G application, electric power artificial intelligence application, energy blockchain application, electric power Beidou application.

"Technological innovation is an important driving force for the digital new infrastructure, taking into account the key construction tasks of the State Grid Corporation's digital new infrastructure and the development needs of the information and communications industry, combined with the trend of strategic technological development in recent years, we believe that in the construction of the digital new infrastructure in the electric power industry, the chip technology, the key technology of 5G + Beidou, the intelligent sensing technology, electric power artificial intelligence technology, etc. will become the key technology leading the future development and the source power to promote industrial upgrading." Xin Yongtan said.

As a core component of the new infrastructure in the new energy field, State Grid New Energy Cloud has a total of 142,000 registered users, 9,206 enterprises, 427,800 visits in August, with a daily average of 614 visitors. Wang Jinsong, deputy director of the development department of the State Grid, introduced the construction goal of the State Grid New Energy Cloud - to build a new energy digital economy platform with Chinese characteristics and international leadership, and to establish "horizontal synergy, vertical connectivity" and "full link, The new energy cloud construction goal is to build a new energy digital economy platform with Chinese characteristics and international leadership.

"The digital economy is an advanced form of economy. The digital economy opens up a fissile transformation of the traditional industrial economy, becoming an important weight for countries to pair in the new round of market competition." Shen Liang, deputy director of the State Grid Big Data Center, pointed out that China's industrial modernization is characterized by traditional industry + digitalization, networking and intelligence. Unlike developed countries, China in the process of industrialization, encountered the opportunity of informatization, determines China's industrialization can not have to complete industrialization and then go to the road of informatization, but rather take the road of deep integration of industrialization and informatization. With the continuous development and improvement of China's digital technology tools and business models, as well as the vigorous promotion of the "new infrastructure", the digital economy will become China's opportunity to overtake in the new round of industrial revolution.

Under the new infrastructure boom, many power companies are exploring and practicing industrial Internet. Fan Weining, general manager of Huaneng Information Technology Company, who was present at the meeting, said that Huaneng's industrial Internet project is divided into three levels: group side, regional side and power plant side. "Huaneng Aidustry Industrial Internet has five core points, which are IT infrastructure cloud, providing powerful storage and computing power; plant equipment data on the cloud, massive industrial data, mining data value; business SAAS (software services through the network), based on the middle platform, framing the enterprise operation center; intelligent application is the core, using IT as a tools, empowering production; crowdsourcing **** win, creating a full-process enterprise ecology." He said.

Electric vehicle charging facilities is one of the key elements of the "new infrastructure". According to the State Grid Electric Vehicle Service Company deputy general manager Que Shifeng introduction, in 2025, the whole society dedicated pile charging volume will reach 42.3 billion kilowatt-hours, public *** pile charging volume of 36.5 billion kilowatt-hours; it is expected that during the "14th Five-Year Plan" period, the whole society dedicated pile and public *** pile*** total charging volume of 253.2 billion kilowatt-hours, the whole society *** pile and private pile*** total charging volume of 253.2 billion kilowatt-hours. unit piles and private piles *** counted 27.2 billion kWh of charging volume.

"The market for electric vehicles interacting with the grid is promising." He said that the total theoretical potential of power interaction between electric vehicles and the grid in 2030 will be more than 1 billion kilowatts, equivalent to 50 Three Gorges Power Station; the total theoretical potential of power interaction between electric vehicles and the grid will be more than 2 trillion kilowatt-hours, and the total market size of the electric vehicle and grid interaction service is estimated to be more than 100 billion yuan at 0.05 yuan / kilowatt-hours. "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 the South China Net Energy Development Research Institute, analyzed the difficulties in digitizing power planning research from practice: in a multi-source heterogeneous data environment, data sources are many and of different calibers, often mixed with incomplete, incorrect, or irrelevant dirty data; the difficulty of obtaining data from the energy industry, the power industry data are scattered in the provinces and cities, and it is difficult to divide up the work to collect them; in the current power planning Research in the various segments of some of the mainstream application software is relatively independent, encapsulated and so on.

"At the same time as the level of informatization is becoming more and more perfect, along with more application systems, hardware and software platforms and equipment, etc. need to be maintained and managed, how to establish an efficient and synergistic network, province, and local collaborative management system, unify the management of authority, and establish a stable and standardized platform operation and maintenance mechanism has become an important challenge for the platform of informatization management. " He said.

Energy transformation to accelerate the throttle

"Playing China's advantages in clean energy, ultra-high voltage, smart grids, etc., and adhere to the 'independent innovation, demonstration first, China leads the way' idea, focusing on clean energy electrification, electrification, intelligentization, integration and other directions related to the overall situation of energy transformation and development, to promote technology and equipment innovation in the fields of energy development, conversion, configuration and use, to promote industrialization, and to seize the commanding heights of global energy technology." Global Energy Internet Development Cooperation Organization Economic and Technological Research Institute, vice president of Li Jun said in the power "14th Five-Year Plan".

She pointed out that the overall path of energy transformation can be divided into three stages. "14th Five-Year" is the incremental replacement, coal power to step on the brakes, clean energy to step on the gas pedal, coal power from the main power supply to regulate the power transformation, new demand by the wind and light storage and transportation to meet the proportion of clean energy installed capacity and power generation continued to improve, than to reach 57% and 45%, respectively. The energy system to achieve peak carbon emissions. 2025 ~ 2035 is the stock replacement, coal power to accelerate the withdrawal, accelerate to the regulating power transformation, clean energy and electrical energy to become the production side and consumption side of the first major energy source. 2035 ~ 2050 is a comprehensive transformation, the full completion of China's energy Internet, coal power to seasonal backup power, clean energy to achieve a comprehensive replacement of fossil energy.

As a "weighty" clean energy, nuclear energy is expected in the "14th Five-Year Plan" will accelerate the development. Qiu Jiangang, vice president of the China Electricity Development Promotion Association and president of the Nuclear Energy Branch, said that by the end of the "14th Five-Year Plan", the operation and construction of nuclear power generation units according to the low and high is expected to reach 90 million kilowatts and 11,000 million kilowatts, respectively. "Preliminary forecast, in 2025, the scale of nuclear power units in operation to reach more than 70 million kilowatts, accounting for about 3% of the country's total installed capacity; nuclear power generation accounted for 6%; relatively efficient coal-fired power generation, the annual carbon emissions reduction can be achieved about 450 million tons; under construction scale of 40 million kilowatts." "During the '14th Five-Year Plan' period, we strive to start the construction of inland nuclear power at the right time in central China, where the power load is large, the status of the grid security operation hub is important, and where renewable energy resources are scarce and the cost is high." He also said.

Luo Jinhua, Deputy Director of the Strategic Planning Department of China Huadian Group, shared "the development opportunities of energy storage in the context of a high proportion of new energy". He suggested that we should pay attention to the positioning of energy storage, do a good job in the layout of energy storage in all segments; strengthen industrial support to promote the development of energy storage in various fields; promote the construction of the market, accelerate the participation of energy storage in the power market process; enhance the level of technology, to promote the high-quality development of the energy storage industry; and improve the standard system, to lead the promotion of the technical standards of energy storage.

Mei Jingyi, Chief Economist of National Energy Investment Group Guohua Investment Company (Hydrogen Company), is very optimistic about the development of hydrogen energy in the "14th Five-Year Plan". She pointed out that the global hydrogen energy development trend has been established and rapid, the domestic hydrogen energy up and down interaction and horizontal competition is increasingly frequent. "China's government attaches great importance to the development of hydrogen energy, each place has to rely on their own industrial base and resource endowment to release the hydrogen energy development plan. On September 16th of this year, five ministries and commissions formally issued the Notice on the Demonstration and Application of Fuel Cell Vehicles, proposing a 'prize instead of a subsidy', which will strongly promote the formation of the hydrogen energy and fuel cell industry chain pointed out."

But at the same time, Mei Jingyi also pointed out that the current hydrogen energy problems: hydrogen energy full chain of key technology performance gap is obvious, equipment and key materials rely on imports, equipment prices are high, hydrogen refueling station initial investment is expensive; hydrogen energy talent is lacking, the lack of industrial supporting system, in hydrogen production, storage, transportation, refueling are the lack of technical standard system. "It is necessary for the government to clarify the market expectations and technology research planning, the national strategy for the development of hydrogen energy, to form the synergy of all parties to promote the healthy and sustainable development of the industry." She suggested.
