Urban energy transformation calls for re electrification Abstract: with less than 1% of the world's land, cities have created more than 80% of the world's economic output and consumed more than 70% of the world's energy. The problem of urban energy transformation is complex, covers a wide range of areas, and it is difficult to coordinate the interests of all parties. In order to gather consensus and break through difficulties, it is necessary to cut in from the problems that need to be solved urgently at present, so as to open the way for solving a series of transformation problems in the future

aiming at the arduousness of national energy transformation, the State Grid Corporation of China reviewed the situation and put forward the strategic judgment of re electrification. Re electrification refers to breaking through the platform stage in terms of quantity, achieving a new round of significant growth, and profoundly highlighting the three characteristics of green, extensive and intelligent in terms of quality. Looking back on the 30 years of reform and opening up, China's urbanization level has increased from 18% to 53%. It is expected that the urbanization rate will continue to increase in the future, and the urbanization level will exceed 65% in 2025. From the perspective of the reality that urban energy prices are not the same and long-term development, it is necessary to enter the re electrification stage, so that China can shoulder the important task of urbanization of large developing countries and solve the dilemma of "rigid demand" for both quantity and quality of energy brought about by urbanization under the national conditions of China's primary stage of socialism

re electrification is the objective demand of urban energy transformation and upgrading

re electrification is the core way of urban energy consumption transformation and upgrading

the direction of urban energy consumption transformation is to build an efficient, green, low-carbon and electrical energy consumption system, optimize the energy consumption structure, and strictly control the total consumption of fossil energy. From the perspective of consumption, re electrification is reflected in the fact that electric energy consumption is more widespread, deeper and smarter to replace fossil energy consumption, which is conducive to promoting the reshaping of energy consumption in the construction, industry and transportation sectors

first, reshape building energy. Indoor air pollution is caused by coal-fired and gas-fired kitchens, and serious pollutant emissions are caused by small coal-fired boilers for heating, resulting in a particularly serious haze problem in densely populated urban areas. It is necessary to replace coal and gas with electricity, build high electrification green buildings, and promote the upgrading of building energy consumption

second, reshape transportation energy. With the rapid growth of car ownership in cities, fuel vehicles have brought serious exhaust pollution and emission problems. It is necessary to replace oil with electricity, build a highly electrified urban transportation system, and promote the upgrading of transportation energy consumption

third, reshape industrial energy. The development of industrialization has been accompanied by the process of urbanization. A large number of industrial enterprises have gathered in cities, resulting in intensive emissions of pollutants such as sulfide, nitrogen oxide and dust. It is necessary to replace coal and oil with electricity, build smart industries, and promote the upgrading of industrial energy consumption

re electrification is the natural result of the transformation and upgrading of urban energy supply

the direction of urban energy supply transformation is to build a clean, intelligent, safe and shared energy supply system, speed up the transformation of coal to clean energy power supply, and form a safe and sustainable energy supply. From the supply side, re electrification is reflected in the accelerated increase of the proportion of new energy power supply such as wind power and solar energy in the primary energy supply, the further increase of the proportion of fossil energy converted into electricity, and the rapid development of strong smart power with efficient allocation of clean energy, which are all natural results of the transformation of energy supply

first, increase external clean power and local clean power, and reduce the phenomenon of abandoning wind, light and water. Cities reduce the direct combustion of local fossil energy, increase the proportion of external clean power supply on a large scale, and increase local clean power production, such as distributed wind power, distributed photovoltaic, urban waste power generation, etc

second, upgrade the city's strong smart electricity and improve the city's energy supply side management ability. Based on smart electricity, build an intelligent urban energy supply and allocation platform, improve the intelligent management system of power production, distribution and trading, realize the friendly interaction between source, load and storage, and promote the realization of high-quality and flexible energy supply, safe and efficient energy supply

third, build "Internet +" smart energy, and realize the integration and innovation of informatization and re electrification. Compared with other industries, the informatization of China's power industry has been carried out earlier, and the application of information systems such as power production, dispatching automation and marketing is mature, which has already reached the international advanced level. At present, power has been integrated with the wave of new technologies such as Yunda mobile intelligence, transforming the power production, consumption and business models. It will also connect with oil and gas pipelines, heat pipes and other energy networks, leading the interconnection of various types of energy flow networks
