For the development of power grids, the “Twelfth Five-Year Plan†outlines the need to further expand the scale of West-East electricity transmission, develop ultra-high voltage, large-capacity, high-efficiency, and long-distance transmission technologies, and rely on advanced technologies to promote the construction of smart grids.
State Grid Corporation of China plans to invest 1.7 trillion yuan in the "12th Five-Year Plan" period, focusing on the following tasks:
First, vigorously transform the development mode of power grids and promote the transformation of energy production and utilization methods.
It is estimated that by 2015, the installed capacity of power generation in the country will increase by 500 million kilowatts to 1.47 billion kilowatts, and the electricity consumption of the entire society will increase to 6.1 trillion kwh on the basis of 4.1 trillion kilowatt-hours, adding 2 trillion kilowatts. The “Twelfth Five-Year Plan†outline clearly stated that it is necessary to improve the level of local processing and conversion of energy, and to ease the pressure of large-scale, long-distance transportation of primary energy. It is necessary to plan the construction of North Shaanxi, Huanglong, Shendong, Mengdong, Ningdong, and Xinjiang. Large coal power base.
In order to meet the needs of building large-scale energy bases and delivering large amounts of clean energy, the State Grid Corporation will accelerate the transformation of the development mode of the power grids, coal and electricity transmission, and vigorously develop transmission to form a large-scale transmission from the west to the east and from north to south. Patterns to achieve optimal allocation of energy resources in a wider range.
Second, comprehensively strengthen the construction of smart grids and create a flexible, safe, and efficient network platform.
The smart grid is a new type of modern power grid formed by integrating advanced sensing and measurement technologies, information and communication technologies, analysis and decision-making technologies, automatic control technologies, energy and power technologies, and grid infrastructure. During the “Twelfth Five-Year Plan†period, the State Grid Corporation of China will comprehensively carry out the intelligent construction and transformation of all aspects of power generation, transmission, distribution, dispatching, etc. to achieve efficient deployment of power resources and efficient use of electrical energy. It is necessary to vigorously promote key substations such as smart substations and build 500 substations with more than 110 kV, realize distributed control through energy self-balancing grid technology, and realize a two-way interactive service system with users to meet the economical efficiency of electricity consumption by users. Diverse electricity options and needs. At the same time, it will promote the rapid development of strategic emerging industries such as energy conservation and environmental protection, high-end equipment manufacturing, electric vehicles, energy storage batteries, and a new generation of information technology.
Third, we will make every effort to promote the use of renewable energy and achieve low-carbon development.
It is estimated that by 2020, China's hydropower capacity will reach 340 million kilowatts, wind power capacity will reach 150 million kilowatts, and solar power generation will reach 24 million kilowatts. The random and intermittent characteristics of wind power and other renewable energy generation will bring higher adaptability to the grid. Claim. State Grid Corporation of China will accelerate the construction of new energy access to power grid projects and power access channels, give full play to the network market functions of the power grid, effectively solve the problem of the absorption of clean energy, strengthen the pumped-storage and energy-storage technologies, and upgrade the energy-supply technology of the power station to promote new energy. Scale development.
Fourth, we must focus on improving people's livelihood and strengthen the construction of distribution networks.
According to the strategic tasks identified in the “Twelfth Five-Year Plan†outline, the company plans to invest RMB 220 billion to implement a new round of upgrading and upgrading of rural power grids and accelerate the construction of a new type of rural power supply network that is safe, reliable, energy-saving, environmentally friendly, technologically advanced, and standardized in management. Reversing the lagging situation of the distribution network, solving the problems of power supply necking and low voltage, improving the power supply capacity and the quality of power supply in rural areas, and satisfying the needs of farmers' lives and agricultural production.
Fifth, play the role of the power grid platform to promote energy conservation and emission reduction.
Continue to implement large-scale small-scale, distribution power grid projects, actively support the development of electric vehicles and other related industries, promote the substitution of electricity by electricity, electricity generation by coal, electricity generation by gas, and further increase the level of electrification.
The State Grid Corporation of China has conducted special research on improving the energy saving of the whole society. The improvement of electrification level is the most effective way to increase energy efficiency. At present, only about 51% of coal is converted into electricity in China, and most of the developed countries are in the range of 75% to 80%. . Therefore, increasing the proportion of electrification and converting coal into electricity is of great significance for improving energy efficiency and low-carbon development.
