State power strives for the "12th Five Year Plan" to speed up power construction

towards the end of 2010, the 12th Five Year Plan has become a hot word. Standing on the node of five-year transition and looking forward to the next cycle, realizing the fundamental transformation of the development mode of power industry has become the development goal of China's power energy industry in the next five years

during the 12th Five Year Plan period, the development speed of electricity must match the regular cleaning power needs and installed capacity of electricity users, and develop in coordination with each other, so as to meet the needs of China's economic and social development. Shu Yinbiao, deputy general manager of State Grid Corporation of China, said at the 2010 Energy Economic Development Forum (Autumn) held recently

The eleventh five year plan is a period of rapid development of China's power industry, but the resulting imbalance in energy transmission has become increasingly prominent. Therefore, Shu Yinbiao said that during the 12th Five Year Plan period, the State Grid Corporation of China will change the current unbalanced mode of energy transmission by building a comprehensive energy transportation system that combines coal transportation and power transmission

at present, China's coal transportation accounts for about 50% of the railway transportation volume, mainly electric coal. In 2006, the proportion of coal transportation and power transmission in Shanxi, Shaanxi and Mengxi was 20:1, and the proportion of power transmission was less than 5%. Transmission is the sixth transportation mode after highway, railway, waterway, aviation and pipeline transportation. UHV is an electric highway with low transmission price and energy transmission. Shu Yinbiao told that during the 12th Five Year Plan period, through the simultaneous construction of coal transportation and power transmission, the proportion of coal transportation and power transmission in the three western regions of China will reach 4:1, and the proportion of power transmission will reach 20%

in fact, relying on the traditional road and railway transportation of coal will not only bring a lot of energy consumption, but also bring huge environmental pressure. According to Shu Yinbiao, power transmission is not only one of the important ways of energy transmission, but also the most economical and clean way of energy transmission. He stressed that it is necessary to change the current unreasonable situation of coal transportation by road and railway, change the mode of energy transmission, break the barriers between provinces, and reverse the traditional way of local balanced development of power supply, so as to achieve a wider range of optimal allocation of resources

according to the distribution of China's energy resources and power consumption demand, China will form a power flow pattern of West to East power transmission and north to South power transmission in the future. Shu Yinbiao revealed that during the 12th Five Year Plan period, 337000 kilometers of 110 (66) kV and above lines and 1.92 billion KVA of transformation/commutation capacity will be added in the business area of the State Grid Corporation of China, which will meet the access and transmission of the newly installed capacity of 380million kW. At the same time, efforts will be made to optimize the allocation of resources to realize the trans regional transmission of power of 250million kW and 1.15 trillion kwh. Shu Yinbiao hopes this move can resolve the contradiction of China's energy transmission

one special four speed-up power supply structure optimization

in addition to improving the energy transmission mode and optimizing the energy layout, adjusting the power supply structure will also play a decisive role in transforming the power production mode. Optimizing the power supply structure is to vigorously increase the proportion of renewable energy generation for the national power company. Shu Yinbiao pointed out

during the Eleventh Five Year Plan period, the installed capacity of wind power in China has doubled continuously, but the difficult problem has made the national power company suffer criticism from all walks of life

at present, the construction of strong smart electricity with UHV as the backbone frame carried out by the State Power Corporation covers all links of power generation, transmission, transformation, distribution, power consumption and dispatching of the power system, which can effectively promote the development and utilization of clean energy, improve the proportion of clean energy in terminal energy consumption, and thus solve the problem of large-scale and long-distance transmission of clean energy power in China

this will greatly improve the ability of China's electricity to optimize the allocation of resources on a large scale, and provide a strong guarantee for the intensive development and efficient transmission of electricity in China's large hydropower, coal power, nuclear power and large renewable energy development bases. Shu Yinbiao explained

in this regard, the State Grid Corporation of China has also set corresponding goals. In 2015, the consumption capacity of clean energy such as wind power and solar energy in China will be increased to more than 100million kW, and the installed proportion of clean energy in the business area of State Power Corporation of China will reach 29.2%, including 11.1% of non-aqueous renewable energy; The proportion of power generation reached 20.2%, of which non-aqueous renewable energy accounted for 8.2%. Shu Yinbiao supercapacitor has the advantages of both battery and traditional capacitor. This will play a vital role in promoting the optimization of energy structure and increasing the proportion of clean energy power generation during the 12th Five Year Plan period, so as to provide a strong guarantee for achieving the goal of energy conservation and emission reduction

during the 12th Five Year Plan period, the State Grid Corporation of China will continue to vigorously promote the most important driving force of scientific and technological innovation. Continue to increase research on UHV transmission technology, wind and solar storage and transmission technology, smart electricity technology, flexible DC transmission technology, UHV DC transmission technology, large capacity energy storage technology, new energy and control technology, distributed energy and micro technology.
