Near the end of 2010, the 12th Five-Year Plan has become a hot word. Looking at the next cycle in the five-year handover node, the fundamental transformation of the development mode of the power industry will become the next five-year development goal for China's power industry.
"In the 12th Five-Year Plan period, the development speed of the power grid must be matched with the power demand and installed capacity, and coordinated development must be carried out in order to meet the needs of China's economic and social development." Shu Yinjun, deputy general manager of the State Grid Corporation of China, recently held in 2010 "Energy The Economics and Development Forum (fall) indicated.
Transmission and transmission of electricity at the same time to ease the contradiction of energy transmission "Eleventh Five-Year Plan" is a period of rapid development of China's power industry, but the resulting imbalance in energy delivery is also increasingly prominent. Therefore, Shuyin Yin said that during the “12th Five-Year Plan†period, the State Grid Corporation of China will change the current unbalanced energy transmission mode by building a comprehensive energy transportation system for coal transmission and transmission.
At present, China's coal transportation accounts for about 50% of the railway's transportation volume, of which electricity is mainly coal. In 2006, the ratio of coal transmission in Shanxi, Shaanxi, and Mengxi was 20:1, and the proportion of transmission was less than 5%. “Transmission is the 'sixth mode of transportation' after roads, railways, waterways, aviation, and pipeline transportation. UHV power grids are 'electric highways' that transport energy.†Shuyin Yin told reporters, “The “12th Five-Year Plan†passed. Coal transmission and transmission will be carried out simultaneously. The proportion of coal transmission in the 'Three West' area in China will reach 4:1, and the transmission ratio will reach 20%."
In fact, relying on traditional ways of transporting coal through roads and railways will not only bring a lot of energy consumption, but will also bring enormous environmental pressure. According to Shuyin, 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 "we must change the current unreasonable conditions of coal transportation on highways and railways and change the mode of energy transmission. We must also break the provincial barriers and reverse the traditional way of balancing the development of power supply on the ground, so as to achieve a more optimal allocation of resources."
According to the distribution of China's energy resources and electricity consumption demand, China will form a power flow pattern of “transmitting electricity from the west to the east†and “from north to south†in the future. Shuyin Yin disclosed that during the "12th Five-Year Plan" period, the State Grid Corporation of China will increase the number of 110 (66) kV and above lines 337,000 kilometers, with substation/commutation capacity of 1.92 billion kVA, which will meet an additional 380 million yuan. The installation and delivery of kilowatts of installed capacity, while increasing the resources to optimize the allocation of power to achieve cross-regional transmission of electricity 250 million kilowatts and 1.15 trillion kwh." Shu Yin-ho hopes that this can resolve the contradiction of China's energy transmission.
In addition to improving the energy transmission method and optimizing the energy layout, the adjustment of the power supply structure will also play a decisive role in transforming the power production mode. "Optimizing the power structure for the State Grid Corporation is to greatly increase the proportion of renewable energy power generation." Shuyin Yin points out.
During the "Eleventh Five-Year Plan" period, China's wind power installed capacity continued to double growth, but the "difficulties in grid connection" made the State Grid Corporation suffer from criticism from all walks of life.
At present, the construction of a strong smart grid with UHV as the backbone grid by the State Grid Corporation of China covers all aspects of power generation, transmission, substation, power distribution, electricity use, and dispatch of the power system, which can effectively promote the development of clean energy. And use, to increase the proportion of clean energy in the terminal energy consumption, so as to solve the problem of large-scale, long-distance transmission of clean energy power in China.
"This will greatly increase the ability of China's power grid to optimize the allocation of resources in a large range, and provide strong guarantees for the intensive development and efficient transmission of electricity for China's large hydropower, large coal power, large nuclear power, and large renewable energy development bases." Road.
In this regard, the State Grid Corporation of China has also formulated corresponding goals. “In 2015, the clean energy absorption capacity of wind power and solar energy in China will increase to more than 100 million kilowatts. The proportion of clean energy installed in the operating areas of the State Grid Corporation reaches 29.2%, of which non-water renewable energy is 11.1%; and the proportion of power generation reaches 20.2%. Among them, non-water renewable energy accounted for 8.2%." Shu Yin-yin pointed out. This will play a crucial role in promoting the optimization of energy structure and increasing the proportion of clean energy during the “Twelfth Five-Year Plan†period, thus providing a strong guarantee for achieving energy-saving emission reduction targets.
During the 12th Five-Year Plan period, the State Grid Corporation of China will continue to vigorously promote the most important development momentum of scientific and technological innovation, and continue to increase the UHV transmission technology, wind and storage technology, smart grid technology, flexible DC transmission technology, UHV Research on DC transmission technology, large-capacity energy storage technology, new energy grid-connected control technology, distributed energy and micro-grid technology." Shuyin Yin finally said.
