On May 15, China Southern Power Grid released the white paper of action plan of China Southern Power Grid for the construction of new power system (2021-2030) (hereinafter referred to as "white paper") in Guangzhou, and held an expert seminar on digital grid to promote the construction of new power system. According to the white paper, China Southern Power Grid will accelerate the digital transformation, enhance the support capacity of digital technology platform and the operation capacity of digital power grid, select the regional power grid with a high proportion of new energy access, build the digital power grid to carry the leading demonstration area of new power system, and comprehensively build a safe, reliable, green, efficient and intelligent modern power grid. Build a new power system with renewable energy as the main source to ensure the security and stability of power grid and reliable power supply in the process of achieving the goal of carbon peak and carbon neutrality.
According to the white paper, during the "14th five year plan" and "15th five year plan", China Southern Power Grid will put into operation 5 million kilowatts and 15 million kilowatts of pumped storage respectively, and put into operation 20 million kilowatts of new energy storage respectively. It will vigorously promote the flexible transformation of thermal power, promote the expansion of hydropower stations with regulating capacity, reasonably arrange peak gas power, and improve the system regulating capacity.
In the future, more and more frequency regulation, peak shaving and emergency power supply will become products and enter the trading market. China Southern Power Grid is developing a trading mechanism to adapt to the participation of emerging market entities such as pumped storage, new energy storage and virtual power plants, designing flexible and diversified market demand response trading modes, and promoting the market construction of demand response in five southern provinces. Not only industrial users. China Southern Power Grid encourages all kinds of power market entities to tap peak shifting resources, and guides non-productive air conditioning loads, industrial loads, charging facilities, user side energy storage and other flexible loads to actively participate in demand response. By 2030, China Southern Power Grid will reduce its peak load by more than 5%.
