The report of the 20th National Congress of the Communist Party of China provides an in-depth explanation on how to promote green and low-carbon development and harmonious coexistence between man and nature. Among them, "Accelerating the planning and construction of a new energy system" is an important guide for the transformation and upgrading of our country's energy industry in the new era, and draws a new blueprint for the development of our country's energy system.
the new situation and new requirements, our country's energy system still needs to accelerate the transformation under the background of the "double carbon" goal. What are the characteristics of building a new energy system today? What kind of support will the new power system provide for the new energy system? How to deal with the relationship between traditional energy and new energy development? In this regard, our reporter interviewed Lin Weibin, director of the Energy Policy Research Office of the China Energy Research
China Energy Media: In the new development stage, what are the new characteristics of our country's energy security? What should be paid special attention to in building a new energy system?
Lin Weibin: Before we talked about our country's energy security, we focused on oil and gas security, because our country relies on imports for more than 70% of crude oil and more than 40% of natural gas. In recent years, with the large-scale development and utilization of new energy sources such as wind power and solar power generation, the security of power supply has increasingly become an energy security issue that needs to be paid attention to. Because wind power and solar power generation are intermittent and unstable, they are deeply affected by meteorological conditions such as wind speed and light.
For example, during the peak power consumption period in summer 2021, the total installed capacity of 35 million kilowatts of wind power in Northeast China Power Grid was only 34,000 kilowatts. In the summer of 2022, the maximum load of the Fujian power grid during the morning peak period of wind power output was only 13,000 kilowatts, less than 1% of the installed capacity. In addition, conventional power sources such as hydropower are also largely affected by meteorological conditions, especially in extreme weather conditions such as high temperature, drought, and cold wave. The power shortage in Sichuan in summer 2022 sounded the alarm for the security of power supply.
As the proportion of unstable power sources in the power system continues to increase, and global warming intensifies, extreme weather occurs frequently, and the problem of power supply security will become increasingly prominent.
