How to transform and upgrade coal power equipment? What is the future of hydropower stations? What is the future grid? Which directions will become the industry's attention in the future? On August 28, the 2022 World Clean Energy Equipment Conference four sub -forums were held simultaneously, focusing on the development of new, new scenes, and new trends from different angles.

New Direction

Digitalization and intelligence are hotspots

Behind the booming of the new energy industry, new challenges have also been made to the construction of the power grid. In the eyes of some guests, with the upgrading of the relevant power grid equipment, this situation will be effectively resolved in the future, and the "prescriptions" they issue include cutting -edge technologies such as artificial intelligence, big data, and flexible interconnection.

At a sub -forum on August 27, a guest showed a photo of new energy vehicles queuing charging during a remote connection. As the sales of new energy vehicles increase, the problem of "difficult charging" users is becoming more and more common.

From the perspective of car users, it is facing the charging problem, and from the perspective of the power grid, the challenge is actually greater.

The charging of an electric vehicle is not large to bring to the power grid, but the accumulation is less. If you choose to concentrate in the same period, the large -scale electric vehicle charging and replacement of the load will increase the difference between the local power grid peak valley. According to Professor Dong Xuzhu, Dean of the School of Electrical and Automation of Wuhan University, by 2030, the number of Chinese electric vehicles is expected to reach more than 80 million. "Assuming that these electric vehicles are charged at the same time, it will bring a huge impact on the grid. Scale China power grid. "

In addition, how does the distributed photovoltaic or wind -energy power station be eliminated? If you directly access the power grid, because the power generation is affected by the weather conditions such as light and air volume, it will increase the difficulty of the operation and maintenance management of the power grid.

"In the past, everyone is generally used by electricity. In the future, many people may have two identities -both users and producers, these are required to ask the flexibility of the power grid." Professor Dong Xuzhu said.

Senior technical experts from Schneider Electric, Li Guosong, thrown a solution: build a digital micro -network, and cooperate with new energy power generation devices to make buildings a unit of self -selling power. According to reports, the company's office building in Europe has adopted the solution. On the one hand, through digital micro -grid means, the electrical appliances in the entire building have been supervised, thereby saving energy and improving energy efficiency. At the same time, this building is equipped with 4,000 square meters of photovoltaic power generation boards and two wind turbines to achieve self -selling and self -selling of electricity.

On the other hand, adjacent buildings have also established digital micro -networks, which can interact between micro -network and micro -nets, thereby reducing pressure on the grid.

Not only is the power grid required digitalization, but also the power generation equipment will also be more intelligent. "In the future, fewer people, unmanned, digital, and intelligent technology will gradually become a standardized configuration of new hydropower units."

new challenge

Vigorous market promotion technology upgrade

"By 2050, if the atmospheric temperature is to be controlled below 1.5 degrees Celsius, the installation of hydropower needs to reach at least 2.6 billion kilowatts." In a sub -forum, Liang Quanwei, deputy general manager of Dongfang Electric Group Dongfang Electric Co., Ltd. In the context of carbon, global hydropower development still has a large market. The market is large, but the challenge is not small, which also has higher requirements for technology.

He mentioned a set of data: "By 2060, the proportion of non -chemical energy consumption in my country will increase from the current 16%to more than 80%, and the proportion of non -fossil energy power generation will increase from the current 34%to more than 90%." New The large -scale access to energy to the stability of the power system and energy security will bring new challenges.

Facing this new challenge, pumping technology has become an inevitable choice.

"The safety, rapid response, stability, and economy of pumping storage have made it the main regulator and stabilizer of the new type of power system in the future." Hou Weirong, vice president of Shanghai Foyte Hydropower Company, also held the same point.

"However, there is still a lot of room for research and development in pumping storage technology." Hou Weirong introduced that the company has been studying a segmentation technology in pumping storage for many years to improve the operational efficiency of pumping storage power stations Essence

Before the maturity application of large -scale and low -cost energy storage technology, in order to cope with the instability of new energy power, the coal electrical unit must assume the role of "bottom protection" on the one hand, and on the other hand, it must provide the main power supply of electricity and electricity. Change the basic power supply to provide reliable power, peak -regulation and frequency and frequency and frequency and frequency and frequency. Bai Jie, deputy chief engineer of North China Electric Power Design Institute, mentioned that the change in the function of coal power units will inevitably promote the transformation and upgrading of coal power technology and equipment.

In this regard, Guo Tingting, chief expert of Datang Group Science and Technology Research Institute, said that in the face of the change of coal -electrical units, they also sorted out and studied the corresponding technology.

The construction of the green power station will also pay more attention to environmental protection. What can I do in the construction field? Kong An, deputy dean of the China Institute of Materials Industry Planning, believes that the key areas of energy -saving carbon reduction in the building materials industry include optimizing the original fuel structure, applicable energy -saving and low -carbon technology, and the implementation of green logistics. In particular, it is necessary to improve the use of new energy and renewable energy. Essence For example, electric energy and hydrogen can replace natural gas as the production fuel for building materials.
