Abstract

Under the goal of "carbon peak and carbon neutrality", the distribution system has gradually developed into a new regional power system with the functions of electric energy collection, transmission, storage and trading, with new forms and characteristics. In this context, First of all, starting from the four aspects of distributed new energy access, electric energy replacement, power electronics application and digital technology, The new characteristics of the power distribution system under the background of "double-carbon" are summarized; Then we analyze the static, dynamic and management problems, The idea of the morphological pattern of the new low-carbon distribution system is also proposed, The key technologies, such as distributed power supply and microgrid technology, source and charge interaction technology, DC power distribution technology and digital management technology, which support the construction of the new power distribution system, are discussed, The gap between the current results and the demand of the new power distribution system is analyzed; last, Coning the key scientific problems facing the construction of new power distribution system, And put forward suggestions on its future technology development direction. As an important resource of social and economic production and life, electric power resources have a significant impact on social development. With the social and economic production and life, the demand for power resources is increasing. The electric power industry is facing increasing pressure for development. The application of power system distribution network automation technology in power enterprises can reduce the development pressure of enterprises, meet the needs of social development goals, provide efficient solutions, and effectively promote the healthy and stable development of power enterprises. Therefore, this paper analyzes the development status and development prospect of automation technology of power system distribution network, hoping to provide useful reference for scholars.
