Under the ne

29、w situation of the energy revolution, the energy supply and demand pattern will see trends that fossil energy is gradually replaced by renewable energy, centralized supply replaced by distributed supply, the long-distance energy supply-demand balance mode replaced by local balance, the one-way suppl

30、y of load-side energy flow replaced by two-way flow, etc. To solve the imbalance and inadequacy of energy supply and demand development in China, focus will be shifted to the supply and demand sides from the strong power grid structure. Promoting the in-depth integration of digital technology and th

31、e energy industry will help: meet the demand for digital, clean, personalized, convenient, and open energy use; enhance peoples satisfaction in access to energy; improve energy utilization efficiency and the use of new energy; reduce energy waste and dependence on traditional fossil fuels; connect a

32、ll parts in the energy industry chain, with a full circulation of data elements, so as to achieve a wider range of collaboration and sharing, and drive the upgrading and development of the energy industry. 10 Digital Technology: Driver of Energy Revolution IV 11 Therefore, under the synergy of the t

33、echnology revolunullon, survival in the digital age, nanullonal strategy, and energy revolunullon, it is imperanullve for power grid companies, which are at the core of the energy industry, to transform into a diginullzed enterprise. Through the transformanullon to a diginullzed enterprise, power gr

34、id companies will build a digital twin grid covering the whole power grid and the whole process of producnullon, and improve the ability to regulate and control complex power grids; data will be used as the core element to enhance producnullvity, release the value of data assets, promote the transfo

35、rmanullon of business and operanullon models, and achieve man- agement and business transformanullon; Power + Compunullng campaign will promote the energy revolunullon and the construcnullon of new energy systems, and build a new ecology of the energy industry involving the related parnulles like th

36、e government, the whole energy industry chain, and users. Through the transformation, the traditional power grid system will turn digital, intelligent, and internet- based, realizing a new form of the power grid, a new business format for power grid companies, and a new ecology for the energy indust

37、ry. That is the so-called digital power grid. 12 13 14 Defininullon and Characterisnullcs of Digital Power Grid02 The digital power grid has three connotanullve propernulles in physics, technology, and value and six main features, namely safe service, green consumpnullon, planullorm empowerment, dat

38、a drive, opening and co-sharing, and value creanullon. The digital power grid gives the power grid more new features and new applicanullon scenarios, and its impact goes beyond the technical category, and it puts more emphasis on number. The smart power grid mainly focuses on the physical characteri

39、snullcs of the power grid with more inclinanullon towards the technical category and more emphasis on smartness . The development priorinulles of the two are dierent, but their aims of development are the same. In some scenarios, they interact with each other, complement, promote each other, and ach

40、ieve integrated development. 15 Mainly driven by cloud compunullng, big data, Internet of Things, mobile Internet, arnullficial intelligence, block chain, and other new-generanullon digital technologies, the digital power grid takes data as the key producnullon factor, and bases on modern power and

41、energy networks and new-generanullon informanullon networks. It is a new energy ecosystem that improves the level of digitalizanullon, networking, and intelligence through the in-depth integranullon of digital technologies with energy enterprises business and management. It is flexible, open, intera

42、cnullve, economical, and shareable, making the grid safer, greener, and more intelligent, secure, reliable, and ecient. 16 Defininullon I 17 The key to building a digital power grid is digital technology. For the digital power grid, a new generation of digital technologies are used to create a digit

43、al twin power grid that covers the entire process of the power grid and all the aspects of production. The essence of digital power grid building is to create value, realize the transformation of internal vertical management of power grid enterprises to flat management, release the value of data ass

44、ets, and realize resource integration and value reshaping. Physical Property Technical Property Value Property The foundation of digital power grid construction is the physical power grid. Various data and information generated by the physical power grid in the process of power transmission and its

45、infrastructure constitute the foundation of the digital power grid. 18 1. Three Key Properties The digital power grid is a product of the power system under the influence of the new round of technological revolunullon and the digital economy. It is a new value-form of the energy ecosystem in the dig

46、ital economy that integrates the tradinullonal power grid with the new generanullon of digital technology. It has three key propernulles. Connotanullon and Characterisnullcs II 19 20 2. Six Main Features The six main features are divided according to the three dierent propernulles. Because of its ph

47、ysical property, the digital power grid provides safe service and green consump- nullon. The technical property makes the digital power grid fully apply the digital technology in data collecnullon, reserve, and compunullng as well as business exploitanullon, which makes the digital power grid empowe

48、red by the planullorm and driven by data. In terms of the value property, the digital power grid not only uses energy flow to achieve economic value but also builds an energy ecosystem to fully exploit the value of data, which features open sharing and value creanullon. With digital technology, it i

49、s able to accurately predict the renewable energy output and power supply load, achieve a local balance between supply and demand of distributed energy, and improve the grids renewable energy consumption capacity. Safe Service Green Consumpnullon Using the new generation of digital technology, it is expected to build a digital twin grid covering the entire power grid and the whole process of production, so that the grid can make intelligent decisions and operate in a stable way; build a trustworthy security protection system with layered protection and level-by-level certi
