Abstract

Abstract:

With the breakthrough, promotion and application of the fifth-generation mobile communication (5G) technology, the world is gradually entering the era of intelligent interconnection. Based on an energy system analysis model (GCAM), the baseline and intelligent interconnection scenarios were designed and simulated, and the development path of China’s energy transformation was explored under the circumstance that the breakthrough of intelligent interconnection technology is accelerated. Results show that compared with the baseline scenario, the energy system is more efficient under the intelligent interconnection scenario, indicating that the primary energy consumption would be 6.2% lower in 2050; the use of digital and intelligent technology will greatly improve the electrification level of final energy use, which would be 9.6 percentage points higher than that in baseline scenario; energy storage technology, smart grid and distributed energy system will accelerate the development and application of renewable energy, the percentage of which in power generation would be 13.3 percentage points higher than that in baseline scenario; China’s green, low-carbon, safe and efficient energy system will be built earlier, and carbon emissions would drop rapidly after reaching their peak, being 5.6 Gt in 2050 (decreasing by 41.8% compared with 2018), making greater contribution to the global response to climate change.
