In recent years, in order to cope with climate change and ensure energy security, countries around the world have increasingly attached importance to the development of clean energy and the improvement of energy efficiency. The report of the 19th National Congress of the Communist Party of China put forward "to promote the revolution of energy production and consumption, and build a clean, low-carbon, safe and efficient energy system", describing the development blueprint of China's energy industry. A new round of energy revolution, marked by the large-scale development and utilization of new energy, and taking re-electricization as the fundamental path, is developing in depth.
As the centralized unit of grid planning and engineering design technology of State Grid Corporation of China, State Grid Economic and Technological Research Institute Co., Ltd. (hereinafter referred to as "State Grid Economic and Technological Research Institute") has actively played the role of technical support and intellectual support of the company's headquarters, carried out in-depth research on smart grid development strategy and application practice, established a complete set of smart grid planning top-level design system, and outlined and formed the company's medium and long-term smart grid development blueprint, Become a pioneer force for the company to march towards world-class energy internet enterprises.
Formulate "smart grid 2030" development strategy
The power grid connects energy production and consumption, is the network hub of energy transmission and conversion, and is at the center of the energy revolution. With the support of advanced new energy technology, distributed generation technology, large-scale energy storage technology, information network technology and intelligent control technology, it is an inevitable trend of power grid development to build a smart grid system of "advanced and efficient, clean and environmental protection, ubiquitous and flexible, transparent and open, and friendly interaction", and then build a wide-area ubiquitous, open and shared energy internet.
Relying on the "China Smart Grid 2030" science and technology project of the National Energy Administration and based on the national level, the State Grid Economic Research Institute comprehensively elaborated the guiding ideology and development ideas for the development of China's smart grid in the future, formed the medium and long-term development strategy of China's smart grid with "one platform, two stages, four types of integration, six features and nine tasks", and proposed that the positioning of the future smart grid is the core configuration platform of the energy internet, It is the core of the modern energy system. It points out that the smart grid will go through two stages of development, transformation and deepening of reform, focusing on achieving breakthroughs in nine areas such as promoting the optimization and complementarity of multiple energy sources, building an active and flexible future distribution network, and gradually realizing the integration and development with the thermal, transportation and information networks, so as to build an energy internet characterized by "advanced, green, coordinated, reliable, flexible and shared". The research results provide strong support for the National Development and Reform Commission and the National Energy Administration to formulate the major policy of "promoting the implementation plan of smart grid construction in China", and play an important role in the innovation-driven development of smart grid.
Draw a technical roadmap for the medium and long-term development of smart grid
Guided by the development strategy of China's smart grid, the State Grid Economic Research Institute has in-depth studied the connotation and characteristics of the energy internet and the new generation of power system, which is in line with the nine key tasks of China's smart grid. From the four perspectives of source, network, load, foundation and common fields, it has proposed "four major categories, 18 minor categories and 50 key technologies", and formed a technical roadmap for the medium and long-term development of China's smart grid, Provide comprehensive technical support for smart grid planning and construction.
In terms of power supply access, the State Grid Economic Research Institute focuses on the technical research of large-scale renewable energy operation control, multi-energy complementary optimization scheduling and other technologies to achieve "extensive interconnection" of the power grid and promote clean replacement; In terms of power grid, we should focus on breaking through the technologies of flexible DC, flexible AC, large power grid control and flexible distribution network to build a "flexible, safe and controllable" modern transmission and distribution network; In terms of users, we will promote the integration and interaction of car and Internet, "Internet plus" marketing services, and demand side response management technology progress, and build a "smart interaction" user service system; In terms of basic and common fields, we will focus on the research of coordinated control of load and storage of source network, large-scale energy storage, power electronics and new electrical materials, and the deepening application technology of cloud mobile intelligence to realize the "open sharing" of power grid. The establishment of the smart grid development technology roadmap will help the company firmly hold the "bull nose" of independent innovation of core technologies, grasp the breakthrough of cutting-edge technologies and key core technologies with international competitiveness in the development of the grid, and realize the company's continuous innovation and leadership in the smart grid field.
Assist in the planning of the first-class smart grid comprehensive demonstration area
In April 2017, the State Grid Corporation of China established a leading group to serve the development of Xiong'an New Area and made a strategic deployment to comprehensively carry out the power grid planning of Xiong'an New Area. The State Grid Economic Research Institute acted quickly, organized professional and capable forces, fully drew on the achievements of smart grid development research, and proposed the "1+4+1" (one display platform, four professional fields, and one support system) smart grid planning framework of Xiong'an New Area, which is in line with the development orientation of the new green smart city in the new area, and built an international first-class green smart grid.
Relying on the advanced information and communication system, the power grid of Xiong'an New Area has comprehensively built a safe and reliable control and command system, a smart and efficient construction operation and maintenance system, a friendly and convenient user service system, an interactive and flexible clean energy use system and a panoramic information platform for smart cities. All power facilities in Xiong'an New Area have achieved full optical fiber coverage, built a super-capacity all-optical backbone communication network and the ubiquitous power Internet of Things, with 100% coverage of online monitoring and intelligent patrol inspection, 100% coverage of smart meters and "multi-meter integration" devices, 100% access to the smart car network for three-dimensional and grid charging facilities, and built a mobile and all-directional virtual online business hall to achieve panoramic perception and intelligent control of power grid status, The user service is high-quality, efficient, friendly and convenient, and comprehensively improves the power supply service level and customer satisfaction. The establishment of the intelligent planning framework of the power grid in Xiong'an New Area will strongly support the power grid in the new area to reach the world-class power grid standards, and the power grid informatization, automation and interaction level will achieve the world's leading.
The State Grid Economic Research Institute, bearing in mind the mission and task given by the State Grid Corporation of China, adheres to the economic research concept of "leading technology and high-quality service", adheres to innovative development, strives to occupy the technological commanding heights, and embeds the top-level design of smart grid into the company's strategic development chain of "building a world-class energy internet enterprise with excellent competitiveness", making positive contributions to the high-quality development of the new era company and the power grid.
