With the continuous advancement of China’s carbon peak and carbon neutralization related work, the investment and construction of new power system has accelerated. On May 19, the video conference on signing the letter of responsibility of 2022 special major science and technology projects of the action plan for tackling key scientific and technological problems of new power system of the state grid was held.
Xin Baoan, director of the State Grid, pointed out in his speech that promoting the tackling of major scientific and technological projects is an urgent need to speed up the construction of a new power system company has identified ten key science and technology projects, covering key core technology fields such as coordinated and optimized dispatching of coal-fired power and new energy power generation, and improving the emergency supply capacity of power system. It has arranged a R & D investment of 200 million yuan , spared no effort to tackle the core technologies of new power system, promoted the transformation of clean and low-carbon energy, and helped to achieve the goal of carbon peak and carbon neutrality.
The new power system takes new energy as the main body, including clean power source, intelligent transmission and distribution, electrification of terminal energy consumption and so on.
In the long run, building a new power system is necessary to achieve the goal of double carbon . Compared with more stable coal-fired power, new energy power generation has the problem of electric energy storage with instantaneous characteristics. When the power demand is strong, it may not be generated, and when the demand is low, it may be over generated. Therefore, it is necessary to use more intelligent transmission and demand management methods, cooperate with the low-carbon transformation of power supply and the power demand on the user side, guide the construction of power grid, and adapt to the instability of clean energy.
In February 2022, the national development and Reform Commission and the National Energy Administration issued the opinions on improving the system, mechanism and policies and measures of green and low-carbon energy transformation, which proposed to strengthen the top-level design of new power system, study and formulate relevant standards for new power system , evaluate the adaptability of green and low-carbon development of existing power system, and carry out green and low-carbon development in power grid structure, power supply structure, source network load storage coordination Improve the technology and optimize the system in terms of digital and intelligent operation control.
▌ list of investment opportunities focusing on UHV and distribution network
As an organic whole, the new power system covers the four links of “source network load storage”. From the perspective of power supply, in order to solve the problems of randomness and volatility caused by the installation of new energy, we must speed up the construction of energy storage projects; From the perspective of power grid, to ensure reliable power supply and safe operation, it is necessary to greatly improve the peak shaving, frequency modulation and voltage regulation capacity of power system, and configure relevant technical equipment; From the user side, the government encourages the diversified development of user energy storage, which requires decentralized energy storage facilities and technologies.
Overall, UHV and distribution network are the focus of attention at present.
Industry experts previously pointed out that “multi energy complementary power supply system + UHV DC transmission channel” is the mainstream solution for new energy in the new power system , UHV bidding may be launched in the first half of 2022, UHV will be put into production in the second half of 2022 and suppliers will begin to confirm revenue.
Guolian Securities Co.Ltd(601456) analyst he Zhaohui said that upstream new energy installation significantly affected by policy promotion will first drive the demand for high-voltage power grid construction, such as UHV AC and DC ; The substitution of electric energy drives the rise of downstream power demand, driving the expansion and transformation of some distribution networks, the implementation and application of DC distribution technology, the construction of urban underground power grid, etc. In the medium and long term, there are significant investment opportunities in DC equipment manufacturing industry; In 2022, it is recommended to focus on Nari Technology Co.Ltd(600406) , Sieyuan Electric Co.Ltd(002028) , Beijing Sifang Automation Co.Ltd(601126) .
Everbright Securities Company Limited(601788) analyst Yin Zhongxin said that under the background of accelerating the construction of new power system, the investment in power grid increased during the 14th Five Year Plan period, and there were great opportunities for structural investment in some fields .
