At the “New Urbanization and First-rate Distribution Network†theme communication event (Chengdu Railway Station) held at the conference, Yingda.com, the subsidiary of State Grid Media Group, published the “The Role of Science and Technology Plan for Distribution Network Development in the Development of Urban Groups in Chinaâ€. analysis report. The report suggests that China's distribution network scientific planning should be based on smart distribution network development guidance, according to the different stages of development of urban agglomeration to implement the principle of differentiation. 
Distribution network planning should pay attention to the rise of urban agglomerations
According to reports, the rapid development of urban agglomerations is playing an increasingly important role in China's economic development pattern. On the one hand, the development of urban agglomerations is inseparable from the support of distribution networks. On the other hand, with the development of urban agglomerations, the negative environmental effects brought about by traditional energy consumption patterns are increasing. Therefore, to ensure the sustainable development of urban agglomerations, it is necessary to realize the scientific planning of distribution networks.
In view of this, the “New Urbanization and First-rate Distribution Network†activity jointly organized by the State Grid Power Group and the Sichuan Electric Power Company is an in-depth interpretation of the relationship between the rise of urban agglomerations and distribution network planning. Adjust and formulate new distribution network planning to provide ideas and lessons.
The reporter learned that the development of urban agglomerations has always been an important part of China’s national economic development strategy. Statistics show that China’s most mature three major urban agglomerations—the Yangtze River Delta, the Pearl River Delta, and Beijing-Tianjin-Hebei urban agglomerations—have contributed more than 40% of output and 24% of employment with a land area of ​​6.2%. Explain the role of the three major cities in the economic development of our country. The "National New Urbanization Plan (2014-2020)" announced by China in March this year will include more urban agglomerations in the national development plan. According to the plan, it is expected that by the year 2030, 32 urban agglomerations will have matured and the urban population will reach 800 million. The construction and development of urban agglomerations will inevitably lead to a new round of economic growth.
Participating experts believe that the rise of urban agglomerations has become an increasingly obvious and increasingly important social and economic phenomenon. Power supply companies must fully consider this trend when planning distribution networks, based on distribution network planning and urban agglomerations. The development of the characteristics of scientific arrangements, in order to achieve distribution network planning and socio-economic development of effective convergence, to ensure the development of distribution networks for economic development, the greatest support.
National Grid promotes distribution network development and planning
It is understood that, in line with China's strategy of accelerating the development of urban agglomerations, the State Grid Corporation of China is making every effort to promote the distribution network development system and plans that are suitable for it. According to the statistics of the State Grid Corporation of China, the State Grid Corporation of China has invested nearly RMB 1 trillion in the distribution network since the “Eleventh Five-Year Plan†period, and the annual average investment is more than double during the “fifteenth†period. In 2014 alone, distribution network investment was allocated 161.4 billion yuan, accounting for 59% of the 750 kilovolt and below grid construction investment.
Zhang Shaojun, deputy director of Sichuan Provincial Energy Bureau, stated at the meeting that in recent years, the urbanization level in Sichuan has rapidly increased and the urban agglomeration in Sichuan and Chongqing has developed rapidly, which cannot be separated from the support of electricity. During the “Twelfth Five-Year Plan†period, the cumulative investment of Sichuan Electric Power exceeded 100 billion yuan, and historical breakthroughs have been made in power construction in Tibetan areas in particular. As the basis for serving the people's livelihood, the distribution network has also made major breakthroughs in recent years, effectively supporting the development of urban agglomerations and urbanization.
Chen Yunhui, deputy general manager of the Sichuan Provincial Electric Power Company of the State Grid, believes that the new goals of economic development and the new level of urbanization construction have put forward new requirements for distribution network planning and construction; the smooth implementation of distribution network planning and construction can be implemented successfully. Economic development and urbanization provide new support. The realization of the above goals requires Sichuan Electric Power to speed up the construction of a modern distribution network, strengthen the upgrading and transformation of distribution networks, and realize the upgrading of rural power grids and the energization of power-free areas.
Distribution network scientific planning should be oriented to intelligent distribution network
At this meeting, the analysis report “The Role of Science and Technology Planning for Distribution Networks in the Development of China's Urban Agglomerations†published by Yingda.com, a subsidiary of State Grid’s Yingda Media Investment Group, believes that distribution network planning should consider and adapt to different urban agglomerations. development stage. From a worldwide perspective, the development of mature large-scale urban agglomerations depends on the spontaneous formation of economic forces. However, China’s special national conditions determine that policies will play a crucial role in the development of urban agglomerations. This means that the development orientation of urban agglomerations and the role of each city within the urban agglomeration will, to a large extent, be set by the government departments on the basis of environmental background and development characteristics. Under such constraints, distribution network planning should fully consider the different development trends and development stages of different agglomerations. In other words, distribution network planning must not only satisfy the economic and social demands for electricity from the perspective of power supply and demand, but also guide economic development from the perspective of structural optimization and adjustment.
The report suggests that distribution network planning should focus on two points. First, considering the overall electricity demand of the urban agglomerations in the region where the distribution network is located, based on the overall needs, determine the macro distribution network planning independently or in conjunction with relevant units. Second, consider the role of the local city in the urban agglomeration and ensure the allocation The power grid plan meets the economic development and industrial upgrading goals of local cities.
The report pointed out that distribution network planning should adhere to the development direction of smart distribution network. According to the report, as an efficient energy development and distribution method, smart distribution network is the development direction of China's distribution network. Intelligent distribution network can not only provide enough power for urban agglomerations, but also promote the development of smart cities through the transformation of urban energy development methods, energy allocation methods and energy consumption patterns. From the point of view of energy development, smart distribution networks can gradually replace renewable energy with fossil energy, thus achieving the development of green energy in urban agglomerations and reducing the environmental pollution from energy development. From the viewpoint of energy allocation, smart distribution networks have adopted Transform each building in the city into a micro power plant, establish an energy internet between the city and the city, and make clean energy efficient configuration among different buildings and different cities. From the perspective of energy consumption model, intelligence Distribution network through access to homes distributed energy, the electricity customers from pure consumers into production consumers, change passive consumption as active consumption.
The report concludes that in order to promote the sustainable development of urban agglomerations, the distribution network scientific planning needs to be guided by an intelligent distribution network and implement a differentiation strategy according to different stages of urban agglomeration development. In the end, the city cluster energy internet is realized through smart distribution networks, and the strong industrial smart grid is used to lead the third industrial revolution and promote the leap-forward development of China's economy.
