Key technologies and development prospect of urban energy internet
With the expanding of city scale, the energy have become increasingly strained. The outbreak of energy crisis and environmental problem restricts the development of the city seriously, and urban energy internet emerges as the times require. It combines the energy in the city (such as coal, oil, natural gas, wind, solar, electricity and other kinds of energy) through the efficient conversion of energy and the close integration of power grid network, traffic network and natural gas network. From the point of the urban energy development, electricity-centric city energy internet model is built. From the point of planning and operating, the key technologies for urban energy internet construction including active distribution grid, clean energy and electric power replacement, business model innovation are put forward. The development direction of turban energy internet is proposed, which can provide some ideas for energy transformation of the city.
