The China Electric Power Enterprise Federation recently released its first power industry value white paper "value of electric power" in Beijing. According to the white paper, the average annual electricity generation in China's power industry has increased by 12.4% in 2002~2011. The installed capacity and generating capacity of the country's electricity increased from 357 million kwh to 1.65 trillion kWh and 4.73 trillion kwh respectively. By the end of 2011, China's power grid has been ranked first in the world for 3 consecutive years.
The rapid development of the power industry, which has changed from the large unit, the ultra high pressure, the national network to the green power generation, the UHV and the smart grid, has strongly supported and promoted the growth of the national economy. According to the white paper, electric power development has supported the national economy for nearly 30 years, with an average high speed growth. Among them, the Twelfth Five Year Plan for the national economy and social development of People's Republic of China, issued in 2011, will be one of the key work of the energy construction. The power grid enterprises make plans for the construction of smart grid, carry out pilot projects, formulate standards, and have made a number of major technical achievements in intelligent electric energy meter, large capacity storage battery, new energy generation and grid control, which make the development of China's smart grid in the forefront of the world. In 2011, China's line loss rate was 6.37%, which was 0.69 percentage points lower than that in 2005. China will continue to be an advanced country with the same power supply load density. By the end of 2011, the capacity of the flue gas desulphurization unit has reached 630 million kilowatts, which is nearly 11 times higher than that in 2005. The power supply reliability of the 10 thousand volt power supply system in China is 99.920%, and the average power outage time is 7.01 hours. The power supply reliability of rural users is 99.790%, and the annual average power outage time is 18.43 hours.
The white paper prospects the application of intelligent technology represented by smart grid in the energy field. According to the white paper, the basic construction of the smart grid will promote the power system of China to be the largest, most capable and intelligent power system in the world, covering power generation, transmission, power transmission, distribution, power use and scheduling, for the adjustment of energy structure, energy conservation and emission reduction, and climate change response. It is of great significance. According to the white paper, by 2020, the power cut time of urban users will not exceed 4 hours per household and rural users will not exceed 17 hours per household.
