Abstract: Industry is the leading industry of China's national economy, and it is also a key area of energy resource consumption and carbon emissions.With the implementation of the carbon peak and carbon neutrality goals, the continuous increase in the electrification rate of terminal energy consumption in the industrial field, coupled with the randomness and volatility of large-scale renewable energy access, pose severe challenges to the carrying capacity, stability and flexibility of the power grid. Studying and judging the demand for industrial electricity load and increasing the layout of smart grid construction are crucial to promoting the green, low-carbon and high-quality development of the industry.
