symposiums series ahead of 2021 world 5g convention: how 5g enables intelligent construction in the energy sector?
seminar | 2021/7/9achieving carbon peak by 2030 and carbon neutrality by 2060 is china’s commitment to the world. the realization of the "double carbon" goal is inseparable from the support of science and technology. as a cutting-edge communication technology, how does 5g contribute to achieving carbon peak and carbon neutrality? recently, experts from various fields like academia and industry gathered together to discuss it.
5g boosts the construction of smart grid
"in national carbon dioxide emissions, energy is the main battlefield while electricity is the main force." gao kunlun, vice director of the global energy interconstruction research institute co., ltd., said at the 5g and carbon peak & carbon neutrality symposium before the 2021 world 5g convention. he also mentioned that the emissions in the energy sector now accounted for 87% of chinese total carbon emissions, in which half of the emissions were related to power generation and fossil energy power generation.
it is reported that hydropower and thermal power generation are controllable as the current power system is based on the traditional ac grid. in the future, when using wind, solar and other power generation energy sources, the uncertainty of power generation will be increased, which will require the development of the power grid in a highly intelligent direction.
"with 5g, we can control more things in a more timely and accurate way. and we can realize the control and operation of the new power system and help the construction of the new power grid based on the original power grid fiber." gao kunlun said.
smart batteries empowered by 5g
storing energy is also an important part of the power system. chen renjie, a professor at beijing institute of technology, said that continuous changes in batteries have supported the transformation of information and communications, and the rapid development of 5g technology has, in turn, brought new opportunities for the development of new energy and smart batteries.
"sometimes timely feedback on battery performance is not achieved, in which 5g technology can give some support. thus it will be a good technique in the future." chen renjie said.
wu feng, an academician of cae, said that the next development phase of batteries is smart batteries. applying 5g into battery packs can improve the uniformity of the entire battery system through information transmission and control, and greatly increase the life of the battery system for energy storage, so as to better realize large-scale energy storage, and contribute to carbon neutrality and carbon peak.
5g needs green development
"5g network has laid the foundation for the digitalization of various industries and then achieved the improvement of energy utilization and carbon emissions reduction by digitalization," said zhu qingfeng, director of the power and energy research department of citc.
while empowering other industries, 5g needs green development.
ding haiyu, director of the wireless and terminals department of china mobile research institute (cmri), introduced that the energy consumption of a single bit 5g is only one-fifth of that of 4g. but the energy consumption of a single station is higher than that of 4g, due to the large number of bits and high speed of the base station. how to reduce 5g energy consumption has become an important task.
as zhang nan introduced, who is the director of the marketing department of huawei's china operators service and software, huawei is building the ultra-lean site and the ultra-lean computer room by designing its computer room outside, and using methods like "green electricity" to reduce the energy consumption of base station. it was reported that huawei is now conducting trials at thousands of sites across china, and its energy consumption has dropped significantly.
