We can foresee significant changes in the source, load, and storage terminals of the future power grid: at the source end, fluctuating clean energy will be connected to the grid on a large scale and in a high proportion; On the load side, a large number of users will welcome the "new identity" of participating in power generation and energy storage; In terms of energy storage, the development of a large number of electrochemical Energy storage, especially hydrogen Energy storage, will greatly reduce the cost of energy storage and transportation. These changes will bring significant changes to the development of the energy internet: in the energy layer, building a comprehensive energy system with multiple complementary energy sources to match the ever-changing energy supply and demand; At the information level, intelligent energy management and control can be achieved through the construction of power transportation coupling networks, power computing power coupling networks, etc; At the value level, the construction of the energy Internet needs to explore the energy Sharing economy, guide the participation of the whole people, and achieve win-win results. The rapid changes in the three ends of source, load, and storage have brought about a demand for integrated and digital transformation and optimization of the "network" end. The continuous deepening of the coupling between internet technology and the original energy system is accelerating the maturity and implementation of energy internet technology. Based on the goal of building a green, low-carbon, and open sharing energy ecosystem, three major technological trends are accelerating the formation: the energy layer, and a green, low-carbon comprehensive energy network will become increasingly important. The energy internet is a complex giant system, and under the dual carbon goal, its main body should no longer be limited to the two major power grids and traditional new energy companies. Instead, more internet companies, digital companies, financial companies, and comprehensive energy service companies will participate in it. By building a new energy ecosystem of "clean, low-carbon, open and shared", we will jointly explore the fast path to achieve the dual carbon goal.
