Grid Stabil
UHV grid boost the rapid development of clean energy - solar, energy - solar power industry
China is in rapid development of industrialization and urbanization, an important period Energy Demand growth with rigid features, expected in 2020 China's primary energy demand will reach 4.5 to 4.9 billion tons of standard coal. The subject of energy reserves, ecological environment, development conditions, and many other factors, China's sustainable supply of conventional fossil energy capacity is about 3.6 billion tons of standard coal, of which 4.1 billion tons of coal, about 200 million tons of conventional oil, natural gas (including coal seam gas, etc.) 300 billion cubic meters, far below the potential demand for domestic energy future, we must develop clean energy, security of energy supply security.
Clean energy into electricity to be used most, including hydropower, nuclear power, wind power, solar power and biomass power generation. It is estimated that by 2020 clean energy into electricity account for more than 82%. Other clean energy use including solar thermal, biomass fuels, the overall size is limited.
Study shows that in 2020 the development and utilization of clean energy in China with total capacity from 670 million to 740 million t of standard coal, energy supply gap could add 60% to 70%. Therefore, the development of clean energy is to protect China's energy supply security and effective way.
The development of clean energy need for special high-voltage power grid
Clean energy resources and energy consumption of the basic characteristics of the distribution center of reverse, the decision to go China's clean energy needs of large-scale development, the development of long-distance road transport.
Clean energy resource-rich country, with massive potential for growth. Hydropower resources in China is very rich in technology development capacity 542 million kilowatts, the highest in the world. As of the end of 2009, utilization of hydropower development in China is only 34%, 60% well below the average level of developed countries. Nuclear Power is rich in resources, the existing site can support the installed capacity of 160 million kilowatts or more long-term installed capacity of 400 million kilowatts to meet needs; abundant uranium resources in China, the future exploration and development of uranium resources by strengthening, strengthening of international cooperation, take advantage of overseas resources, nuclear fuel supply could meet the needs of our large-scale development of nuclear power. Development of wind power technology in China exceeded 10 million kilowatts, mainly located in the "Three North" (Northeast, Northwest, North) region, eastern and southeastern coast and nearby islands. Abundant solar energy resources, mainly in the Tibet Qinghai, Xinjiang, Mongolia, Gansu and Ningxia provinces, the scale can be developed more than 2 billion kilowatts installed capacity.
Remaining technical hydropower resources in China is about 80% of the distribution can be developed in Sichuan, Yunnan, Tibet, Southwest China, the land wind energy mainly in the northwest region, and two-thirds of the energy demand concentrated in the east. In the western region is lagging behind economic development, low power load demand, eliminating the assimilative capacity of clean energy generation is limited, large-scale development to be sent to the load center in the eastern region, to expand the scope of consumer satisfied. Energy Research Institute under the State Grid
research results, if the wind is only satisfied consumers in the province, in 2020 the country's wind power can be developed about 50 million kilowatts-scale, cross-regional networking through the ultra high voltage transmission expansion of clean energy consumptive ability to develop national-scale wind power up to 1 kw. Clean energy requirements of large-scale configuration of objective determines that China must build a large-capacity, long-range energy transmission channel, ultra high voltage grid is clean energy development and transmission bearing the inevitable choice.
UHV has a large capacity, economic transmission distance, low power consumption, land occupied, and good economic advantages of clean energy to achieve a variety of large-scale, long-distance transport, and promote efficient use of clean energy. West, north east of a large energy base load centers in the region with the distance from 800 to 3000 km, 750 kV, such as relying on the exchange, 500 kV and ± 600 kV DC level, ± 500 kV transmission technology, beyond the economic delivery distance, network security and stability are not protected. Large-scale construction of nuclear power base also needs a strong support network.
2020, the National Grid will form a "three China" as the main power grid by the end of 1000 kV power grid in Northeast, Northwest 750 kV power grid as the main delivery side, joins the large-scale coal bases, water base, nuclear power base, renewable energy base and the main load center and strong levels of coordinated development of intelligent power grid.
