  At the recent 2021 China Southern Power Grid Energy Development Forum and China Southern Power Research Institute's research results release conference, Wang Tong, President of China Development Research Institute, said that achieving the "dual carbon" goal as scheduled is a challenge and an opportunity.

From 2020 to 2050, the energy system needs to invest about 100 trillion yuan in new energy. The new power system with new energy as the main body will undergo revolutionary changes. New growth points and huge business opportunities will be highlighted. Low-carbon technology, clean energy materials, The new energy automobile industry chain and other emerging fields have broad prospects.

  At the meeting, China Southern Power Institute released a series of research results such as the "Report on China's Power Market Reform", "Report on China's Power Industry Investment Development", and "Guangdong-Hong Kong-Macao Greater Bay Area Power Development Report".

Experts and scholars from the energy field jointly discussed new ideas and measures to build a new power system and help carbon peak and carbon neutrality.

  Wang Tong suggested speeding up the construction of new power systems, including research on new energy access modes, strengthening conventional power regulation capabilities, coordinated planning of power grids at all levels, grid digital transformation, new generation dispatch systems, integrated energy service models, and major technological innovations.

  Zhou Xiaoxin, academician of the Chinese Academy of Sciences and honorary dean of the Chinese Academy of Electric Power Sciences, said that on the implementation path, it is necessary to implement the construction of a clean, low-carbon, safe and efficient energy system and the construction of a new power system with new energy as the main body.

He believes that energy storage can be achieved through two paths. One is to respond to the short-period (intraday) volatility and intermittent operation flexibility adjustment needs of wind and new energy power generation. Pumped storage, electrochemical batteries, compressed air and other energy storage can be used. Technology; the second is to deal with the long-term (weekly, monthly, and cross-season) output fluctuations of wind and new energy power generation, the imbalance of energy and power supply and demand, and the energy storage demand for energy and power supply under sudden disasters, mainly using green technology to produce and store hydrogen and Gas/liquid fuel (such as methane, methanol, ammonia), etc.

  Song Yonghua, President of the University of Macau and Director of the State Key Laboratory of Smart City Internet of Things, believes that Macau has basically entered the carbon peak stage. It should be guided by policy and driven by technology to actively build Macau into a carbon neutral pilot demonstration with world influence. city.

He also proposed 7 paths, including vigorously promoting the electrification of land transportation, promoting hydrogen-powered marine transportation, developing local clean power sources, promoting low-carbon buildings/parks, intelligent transformation of urban power distribution networks, and actively participating in the Guangdong power market to purchase green power Wait.

  Investment is a "barometer" that reflects the state of the industry.

The "China Power Industry Investment Development Report" disclosed that since 2010, my country's wind power installed capacity has increased by more than 10%.

In order to solve the contradiction between the intermittent characteristics of new energy and the stability of power supply, the investment in high-efficiency and high-capacity energy storage should be increased, and the investment scale of new energy storage devices such as regulated power supplies such as pumped storage and electrochemical energy storage should be increased.

  The “Report on China’s Power Market Reform” suggests that under the background of “dual carbon”, power market reform is facing many challenges, and the power market system should be improved to guide the orderly development of new energy; expand the scope of market allocation and accelerate the promotion of regional unified power Market construction; innovative mechanisms, compatible with new market entities, and smooth distributed resource consumption channels; perfect price formation mechanisms to promote the coordinated development of new energy and regulated resources; reform transmission and distribution pricing mechanisms, strengthen investment incentives, and optimize new energy layout.

  The "Guangdong-Hong Kong-Macao Greater Bay Area Power Development Report" disclosed that in 2020, the Guangdong-Hong Kong-Macao Greater Bay Area clean energy installed capacity of 54.14 million kilowatts, an increase of 11.2% year-on-year, accounting for 63.8% of the total installed capacity, clean energy power supply within and outside the region accounted for more than 60 %; The 500 kV internal and external double loop network in the Pearl River Delta has been built, the power supply capacity of Hong Kong and Macau has been further enhanced, and the internal grid of the Greater Bay Area has become more and more perfect.

In 2020, the Kunliulong DC project will be completed and put into production. The transmission capacity of the western provinces to the Guangdong-Hong Kong-Macao Greater Bay Area will increase by 5 million kilowatts, and the power supply guarantee capacity outside the region will be further improved.
