Shu Yinbiao: In the future, the ecological power system and renewable energy will be interconnected

China Energy Storage Network News: From June 17 to 23, Qinghai Power Grid achieved 7 consecutive days of renewable energy power supply to meet the energy needs of the entire province. This is a practical case of the longest clean energy power supply in the world. "At the 2017 Dalian Summer Davos New Champions Annual Meeting, Shu Yinbiao, Chairman of State Grid Corporation of China, used a series of data and examples to introduce the achievements of State Grid in promoting energy substitution and clean energy reform, and exploring a path with Chinese characteristics.

Data shows that China's installed capacity of renewable energy accounts for 24% of the world's total, and its newly installed capacity accounts for 42% of the world's increase, making it the leader in the use of new and renewable energy. During the 12th Five-Year Plan period, my country's nuclear power, hydropower, wind power, and solar power generation installed capacity increased by 2.6 times, 1.4 times, 4 times, and 168 times, respectively, driving the proportion of non-fossil energy consumption to increase by 2.6 percentage points to 12%, exceeding the 11.4% target set out in the 12th Five-Year Plan.

The clean energy technology revolution has always been the most important issue. Shu Yinbiao introduced that State Grid is a company that continuously innovates technology. By developing UHV transmission, improving the level of grid intelligence, vigorously implementing electricity substitution, and improving the system's balance and regulation capabilities, it promotes China's energy structure adjustment and clean energy reform. "As of the end of 2016, State Grid has connected a total of 130 million kilowatts of wind power and 70 million kilowatts of photovoltaic power generation to the grid, making it the world's largest grid for new energy grid connection. It has independently developed the world's most advanced UHV transmission technology, and has 20 UHV projects in operation or under construction. It has built an electric vehicle fast charging network covering 121 cities in China and a smart car networking platform connected to 161,000 charging piles, providing full-range services for 1 million electric vehicles."

In addition, by the end of this year, coal-free heating will be achieved in the coal-free zone of Beijing, Tianjin and Hebei, and people will use electricity for heating at home, which is not only cost-effective, but also safer and more convenient. In particular, from June 17 to 23, the Qinghai power grid achieved 7 days of continuous clean energy supply to a province, which is a practical case of the longest power supply time using clean energy in the world.

"At present, my country has installed 427 million smart meters and has built a number of internationally leading smart grid demonstration projects, including multi-terminal flexible direct current, unified power flow controller, national wind, solar, storage and transmission. In the future, the power grid will continue to invest in the development of an ecological power system to achieve flexible and extensive interconnection with renewable energy under the premise of safety and control," said Shu Yinbiao.

It is understood that at the end of 2016, China's wind power and solar power installed capacity were 150 million kilowatts and 80 million kilowatts, both ranking first in the world. At the same time, we will vigorously reduce coal and coal-fired power production capacity, promote the use of electricity instead of coal and oil in the fields of transportation, industry and commerce, and residents' lives. From 2016 to 2017, more than 440 million tons of coal production capacity will be withdrawn, and more than 50 million kilowatts of coal-fired power capacity will be eliminated, stopped, or slowed down, making room for the development of new energy.
