The "Twelfth Five-Year Plan" special grid plan will determine the future construction plan and development goals of China's power grid. State Grid Corporation attaches great importance to it, and has organized and completed the regional power grid planning of the State Grid Corporation, and recently submitted it to the National Energy Administration. The next step is to strengthen leadership, increase strength, set up special classes, do a good job of reporting to government departments, relevant experts, and intermediary consulting agencies, and fully promote the inclusion of the State Grid Corporation's grid planning and UHV key projects into the national grid planning.
Fully promote the development of UHV power grid
In 2013, the UHV power grid will enter a new stage of comprehensively accelerating development and large-scale construction. Go all out to advance the preliminary work of UHV, to ensure that UHV will be delivered in four during the year
"Straight" started (Huainan-Nanjing-Shanghai, North Zhejiang-Fuzhou, Ya'an-Wuhan, Mengxi-Changsha, Ningdong-Zhejiang, Ximeng-Taizhou, Mengxi-Hubei), "Sijiao-Nanjing" , Jindongnan-Xuzhou, Jing
Bian—Weifang, Wuhan—South Anhui), the roads of “two intersections and two straights†(Zhangbei—Nanchang, Nanyang—Huainan, Hamibei—Chongqing, Zhundong—Sichuan), and the “Sanhua†UHV synchronous power grid and "Two vertical and two horizontal" backbone grids.
Further strengthen and improve the collaborative working mechanism with local governments, in accordance with the principle of localization, and ensure that the UHV project achieves a breakthrough in the preliminary work. Improve and perfect the organization system, and provide strong organization and manpower guarantee for UHV project construction management.
Focus on building a modern distribution network
Improve the concept of distribution network planning, deepen research on typical power supply modes, and accelerate the construction of distribution network informatization.
Solve the problem of weak rural network as soon as possible
Continue to implement the rural power grid upgrade project; accelerate the construction of urban and rural junctions, county towns, and small town power grids; accelerate the solution of the problem of weak connection and "low voltage" between the county grid and the main grid; solve the problem of electricity consumption by the unpowered population as soon as possible through the largest extension of the power grid To improve people's livelihood.
Actively support and serve the development of new energy
Strengthen technical research, standardize on-grid management, and focus on solving the contradiction between rapid development of new energy and market consumption.
Speed ​​up technological innovation and demonstration project construction
Rely on technological progress and insist on independent innovation. Accelerate the research on key technologies such as ± 1100 kV DC and direct connection of UHV DC to 1000 kV power grid, and complete the research and development of key equipment to meet the needs of engineering construction; in-depth research on the operating mechanism and laws of UHV AC / DC hybrid large power grid, Optimize operation control strategies and improve risk prevention and control measures; build a new generation of intelligent substation demonstration projects, accelerate the promotion of Dalian and Zhoushan flexible DC transmission technology demonstration projects and the second phase of wind, solar, and storage expansion projects, and build key city distribution automation systems and power consumption information Acquisition system, continue to implement power fiber to the home in economically developed areas such as Shanghai; actively participate in the development of international standards and specifications related to UHV and smart grids, and further enhance the company's influence and voice in the development of international standards.
Construction of several smart grid demonstration areas
Accelerate the construction of smart grid, focus on enhancing the grid's ability to bear and adapt to new energy generation, distributed energy, electric vehicles and other energy utilization methods, realize the interaction between the power system and users, promote the upgrade and transformation of all links and elements of the power system, and improve the power system The level of safety and overall efficiency drive the development of related industries.
Strengthen smart grid planning, determine key technology routes and development models, and formulate smart grid technology standards through key technology R & D, equipment development, and demonstration project construction. Establish systems and mechanisms that are conducive to the popularization and application of smart grid technologies, and implement electricity price policies that are compatible with the development of smart grids. Accelerate the promotion and application of smart grid technology and equipment, improve the level of grid informationization, automation, and interaction, and improve the grid-connected transmission capacity of renewable energy and distributed energy. Actively promote the construction of microgrids, smart power communities, smart buildings and smart meter applications. During the "Twelfth Five-Year Plan" period, several smart grid demonstration areas were built, striving to stay ahead of the world in key technological innovation and equipment R & D.
