The new generation of DI technologies is rapidly penetrating into many fields of social economy, constantly driving changes in ways of production and living and business management models. Major countries around the world have made a series of major deployments in the field of digital transformation, promoting industrial digitization and intellectualization, facilitating the deep integration of the digital economy with the real economy, intelligent systems and physical systems, and promoting highquality socioeconomic development.
As the power industry is closely related to the national economy and the people’s livelihood, it is necessary to build a DI power system, explore the value of power data, enhance data application and commercialization capabilities, and drive level upgrading in the power industry through “power computational power” by seizing historical opportunities, taking digital transformation as the starting point, carbon reduction and consumption reduction as the goal, and implementing the strategydriven and innovationdriven development plan.
DI technologies will be adopted to build a nerve system of the power system, and endow the power system with comprehensive sensing, intelligent decisionmaking, realtime control capabilities. In the future, DI technologies will comprehensively enhance the information collection, transmission, processing and application capabilities of the power system, and realize comprehensive data analysis and rapid intelligent decisionmaking, thus driving the integration of traditional power facilities and new digital facilities, and promoting intellectualized power system dispatching and smart operation and management of enterprises. On this basis, it is possible to break barriers between energy and information, business, capital and value, promote the integration and development of industries, innovate the construction of new digital platforms including energy transportation, energy information and energy finance, and construct an energy interconnection ecosystem featuring sharing, cogovernance and winwin.
Based on the functional positioning and development needs of DI power technologies in the power industry, this report analyzes the development status, major applications and R&D directions of key technologies from a technical perspective, and evaluates the potential value of DI technologies in power systems, power enterprises, and industrial cooperation. This report is composed of 8 chapters. Chapter 1 analyzes and proposes the development objectives and positioning of DI power technologies from the current situation of DI technologies development and transformation needs in the power field; Chapters 2 to 7 study six key technologies, including sensor (measure) technology, communication technology, control (protection) technology, chip technology, big data _x000c_and blockchain, and artificial intelligence; Chapter 8 summarizes the development trend of key technologies, and looks forward to and depicts ten typical application scenarios of DI power technologies from four aspects, namely, the construction of DI power system, the innovative management of intelligent enterprises, the industrial integration development of “energy information ” and the empowerment of power big data, in order to accelerate the integration of new generation power system into a digital economy and intelligent society and build a digital intelligent ecosystem.
As one of a series of reports on key technologies for Global Energy Interconnection, this report includes the research results related to the development of power digitalization and intellectualization technology from Global Energy Interconnection Development and Cooperation Organization. The research team visited North China Electric Power University, Hengtong OpticElectric, China Mobile, Linghang Think Tank, and Prysmian Group (Italy), as well as other GEI members, Thinktank Coalition, and University Alliance, and received help and support from many experts and scholars in the fields of electronic information, data analysis, artificial intelligence, and experts from the Advisory (Consultant) Board and the Technical (Academic) Committee of GEIDCO. We would like to express our gratitude here. However, there might be inadequacies due to the limitation of knowledge, data and preparation time. Comments and suggestions are welcome for further improvements.
