With electric power technology, electricity replaced steam, promoting the production model to develop towards the era of electrification. With information technology, computers and network applications promoted society to enter the age of information. With capital at its core, the means of production, such as factories and technologies, have become the key factors of production in the industrial economy. The new generation of digital technologies promotes the comprehensive integration of digitalization and industries, bringing fundamental changes for modes of production and management. The economic form of society is changing from the industrial economy to the digital economy, and the structure of factor inputs is being optimized continuously. By stimulating the huge innovation potential of data , a new driving factor, enterprises are making continuous efforts to catalyze and transform the role of technology, management, labor, land, capital factors, and others, to significantly enhance the total factor productivity, greatly improve the core competitiveness of enterprises and the entire industry, and promote deep economic and social reforms. (The 1760s) The First Industrial Revolunullon (The Mid-20th Century) The Second Industrial Revolunullon (The 1950s) The Third Industrial Revolunullon (Currently) The fourth Industrial Revolunullon The disruptive technologies in the industrial revolution have increased productivity, brought about adjustments to production relations, contributed to the formation of a new economic development mode, facilitated changes in economic structure and industries, and promoted profound social transformation. Social Changes Brought by Digital TechnologiesI 05 With the connullnuous in-depth integranullon of digital technology and the real economy, the consumpnullon model has gradually trans- formed from oine consumpnullon to online consumpnullon; monetary payment is gradually replaced by mobile payment; people work at home by teleworking rather than in the oce; cloud meenullngs, cloud educanullon, cloud tourism, and other cloud + services have become reality. All people have already gonullen used to the ecien- cy, convenience, and personalized services brought by digital tech- nologies to their life and work. People expect the service they receive with higher quality, higher levels, and lower prices. 06 Survival in the Digital Age: A New Theme II 07 With macroeconomic development becoming a new normal, build- ing Digital China and developing a digital economy have become nanullonal strategies. In order to eecnullvely support the construcnullon of Digital China, the government has vigorously encouraged innova- nullon in the big data technology industry, promoted the development of a digital economy with data as a key element, and taken full advantage of big data to facilitate the modernizanullon of nanullonal governance and to safeguard and improve peoples livelihood. Building Digital China is a new policy to meet peoples growing needs for a benuller life and a new driving force to lead high-quality economic development. To accelerate the construcnullon of Digital China is to adapt to the new development direcnullon, fully imple- ment the new development concept, culnullvate new kinenullc energy by informanullzanullon, which promotes new development, and creates new prosperity. 08 Digital China: A National StrategyIII 09 A new generation of digital technologies opens up new ways for the in-depth energy revolution. Under the new 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 supply 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 the 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 all 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 technology 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 grid 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 transformanullon 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 the 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 industry. 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, data 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 characterisnullcs 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 achieve 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 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, interacnullve, 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 digital 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 assets, 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 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 digital 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 physical 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 empowered 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 is 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 certification to provide u
