page views： With the gradual increase in the proportion of non-fossil energy, the consumption side of energy consumption needs to be more flexible, and the connection between energy supply and demand will be closer, which puts forward higher requirements for improving energy consumption elasticity, intelligent level, and independent supply capacity. At present, our country's energy consumption side is still facing institutional and mechanism constraints, and it needs to be driven by the transformation of the consumption structure of major energy-using industries, strengthen the coordinated transformation of energy consumption and production, and take multiple measures to guide the green and low-carbon transformation of energy consumption.
The change trend of energy consumption side under the new energy system
The level of electrification and intelligence of energy consumption continues to improve. Electrification is an important way to promote energy structure adjustment and green and low-carbon transformation. It is an important measure to support new energy systems and build new power systems, and help achieve peak carbon dioxide emissions carbon neutrality. With the rapid development of digitization and intelligence of energy systems, new power supply technologies such as intelligent microgrids, virtual power plants, integrated energy services, and energy big data centers have emerged. These new technologies and new formats are mainly located on the consumer side, changing the traditional energy supply model and energy consumption behavior. Their commercial application will effectively improve the operation control, decision-making regulation, resource allocation, and risk early warning capabilities and levels of new power systems, further enrich the application scenarios of power consumption, and accelerate the electric energy substitution of end point energy consumption.
the flow of energy consumption space is more complex. In the future, the trend of coordinated development of large-scale wind power photovoltaic bases and distributed energy sources has become inevitable. Compared with the traditional centralized energy supply model, the energy channels on the consumer side under the new energy system are more diverse, including both remote consumption from new energy bases, and on-site consumption from rooftop photovoltaics, small wind power, biomass power generation, and new energy storage. The boundaries between energy consumers and producers will become blurred, and the flow of supply and demand will become more complex. On the one hand, the bearing pressure of power distribution systems has increased, and it is urgent to upgrade and support new energy storage facilities. On the other hand, the uncertainty of demand prediction and timely consumption of energy consumption has increased, posing challenges to energy system planning and operation and maintenance management.
The interaction between energy consumption and supply has increased. With the high-quality development of the economy and society, the continuous improvement of people's living standards, and the increasing intensity of extreme weather, the national electricity load has increased year by year, showing significant characteristics such as high peak values, large peak-to-valley differences, and double peaks in summer and winter. The stability of energy supply dominated by renewable energy is greatly affected by seasons and extreme weather, and the energy system will inevitably face an increase in supply volatility and randomness. The contradiction of energy oversupply or shortage caused by short-term energy space-time mismatch will be further highlighted. It is urgent to change the feedback mode of energy supply and demand regulation. In addition to the energy supply side of the power generation capacity adjustment, energy consumption side also needs to explore more flexible ways to use energy, according to the power supply and demand season, period characteristics and supply and demand tensions actively change their own electricity habits, improve energy consumption elasticity, actively adapt to new energy supply models, respond quickly to dynamic changes in supply, adjust consumption or consumption sources to restore supply and demand balance as soon as possible.
