The new power system with new energy as the major energy resources has become the development direction of the future power grid. In the distribution system, it is manifested in the high penetration of distributed generation (DG), e.g., photovoltaic, wind power and electric vehicles (EVs). The carrying capacity of the distribution system for DG and EV is of great significance to the planning of the system. This paper firstly analyzes and summarizes the theoretical basis for evaluating the carrying capacity of distribution systems for DG and EV from four perspectives: the modeling method for DG and EV uncertainty, the site selection strategy of DG and EV charging pile/station, the evaluation index of distribution system’s carrying capacity, and the carrying capacity evaluation method. Then the paper analyzes the key technologies for improving the carrying capacity of the distribution system from the four aspects of source, network, load and storage. Finally, combined with the development trend and characteristics of China's new power system, the research on the carrying capacity of distribution systems is prospected. This review provides a useful reference for the planning of large-scale distributed new energy and new loads in distribution systems.

Key words: distribution system, distributed generation, electric vehicle, carrying capacity evaluation, carrying capacity improvement
