Abstract: The realization of carbon peak and carbon neutral targets requires the sustainable and large-scale development and utilization of renewable energy. The large-scale new energy grid connection represented by the rooftop distributed photovoltaic development of the whole county will bring great challenges to the stable operation of the existing distribution system. Firstly, the concept and characteristics of the new power system are analyzed. On this basis, the five-tier technical framework of the new power distribution system is proposed, and then the development path of the five dimension levels is further discussed. The corresponding application scenarios are exemplified for different dimension levels. Finally, several suggestions are put forward for the research and storage of the new intelligent power distribution network technology, with a view to providing technical development direction reference for the future construction of new distribution.
