On December 6, Wang Zhongying, deputy director of the Energy Research Institute of the National Development and Reform Commission, said that China's power grid currently has enough space to accommodate the development of renewable energy. When the power of renewable energy access to the power grid is close to 20%, it is necessary to consider the construction of the future power system. However, the proportion of China's current access network does not require the country to invest heavily in the power grid.
Wang Zhongying made the above statement at the "21st Century Low-Carbon China Development Summit." Wang Zhongying pointed out that on the 9th of this year, the Intergovernmental Panel on Climate Change (IPCC) issued a Special Report on Changes in Renewable Energy Sources and Mitigation of Climate Change, which assessed 164 development programs worldwide. “This is an expert report written by a specialist committee composed of 194 countries for nearly two years.†Wang Zhongying stated that the report pointed out that when the proportion of electricity generated by wind power is within 20% of the local grid, the power grid will hardly increase. Additional costs.
The State Electricity Regulatory Commission recently released in Beijing "Wind Power Safety Supervision Report" shows that China's wind power accounted for 1.5% of power generation. "Our power grid has good advantages as well as resource advantages. The current ratio has enough space to develop renewable energy sources," said Wang Zhongying.
Renewable energy development will force reform
Shi Lishan, deputy director of the New Energy and Renewable Energy Division of the National Energy Administration, pointed out at the meeting that during the “12th Five-Year Plan†period, China will increase the proportion of renewable energy and comprehensively increase industrial capacity, especially the development of wind power and Solar Energy. We will build an intelligent power system based on nuclear power, with hydropower as the main source of electricity, such as wind power and solar energy.
"The power system is very important in the energy system." Wang Zhongying believes that the future power system should not only be able to deal with the volatility of the user side, but also should deal with the volatility of the power generation side, that is, for renewable energy, such as intermittent wind power.
For the future power system, Wang Zhongying said that it is possible to 100% accept renewable energy. "It is not safe to accept more renewable energy. I think this is not correct. First, we must change our thinking." Wang Zhongying pointed out that 100% of renewable energy sources can receive new electricity and energy systems. "It's just what the new power system costs. We need to do research."
According to its introduction, the German Energy Agency has spent three years focusing on the core theory of “100% acceptance of renewable energy†to carry out an energy transformation strategy study and found that by 2030, 100% of renewable energy grids will be refitted to enable end-user electricity prices. The cost rises by two cents per degree.
Wang Zhongying stated that the power system reform has been appealing for many years, but the adjustment of the interest distribution mechanism is too difficult. In the future, large-scale, transcendental development of renewable energy will promote the reform of the power system and energy transformation. "By 2030, when renewable energy reaches a certain percentage and the power system transformation is successful, we will have an economically stable and sustainable energy system. At that time, we can also develop renewable energy on a larger scale." Wang Zhongying said.
Shi Lishan believes that when China's energy consumption reaches its peak after 2030-2040, it can be based on nuclear power, with hydropower as its main source, new energy as its main source, and coal-fired power as the supplement to provide future energy of 3 billion tons of standard coal. At the same time, it focuses on building a smart grid, which will revolutionize China's power management system.
"Eleventh Five-Year" Urbanization Energy Consumption Increased 35% YoY
Li Xinmin, inspector of the Department of Pollution Prevention and Control of the Ministry of Environmental Protection, said at the meeting that China’s energy progress in the energy sector is significant and energy efficiency is increasing at a rate of 1-2% per year. However, in recent years, the heavy chemical industry and energy-intensive industries have developed rapidly. “Industrial Structure The change offset or slowed down the decline in GDP energy intensity."
According to the latest statistics, acid rain frequency in the first half of 2011. Cities with a frequency of more than 25% are mainly distributed in most areas of Zhejiang, Fujian, Jiangxi, Shanghai, Hunan, and Chongqing, and more than 75% of the cities are mainly concentrated in Zhejiang, eastern Jiangxi, and southwestern Chongqing. Li Xinmin said that this reflects the development of the local economy. The increase in coal consumption has brought about an increase in the settlement of acid substances.
In addition, the total amount of nitrogen oxide emissions is also increasing. Li Xinmin pointed out: "In the fourteen years from 1996 to 2009, the rate of urbanization has increased by one percentage point, and emissions of about 195,000 tons of nitrogen oxides have been emitted. The increase in nitrogen oxides brought by the development of motor vehicles has reached 86,000 tons. about."
The Environmental Protection Institute of the Ministry of Environmental Protection has analyzed the energy consumption and pollutant emissions in the 14 years and found that urban development contributes more to the increase in energy consumption. “The development of urbanization actually promotes the increase of energy consumption and pollutant emissions,†said Li Xinmin.
According to the analysis, from 1996 to 14 years of 2009, urbanization increased by an average of one percentage point, requiring approximately 49.4 million tons of standard coal to consume more energy. The average energy consumption during the “Ninth Five-Year Plan†period was 41.68 million tons, and averaged during the “10th Five-Year Plan†period. Energy consumption is 46.42 million tons, and during the "Eleventh Five-Year Plan" period, it has risen to 62.74 million tons of standard coal, an increase of 35%.
