ABSTRACT = {Aiming at the consumption problems caused by the high proportion of renewable energy being connected to the
distribution network, it also aims to improve the power supply reliability of the power system and reduce the
operating costs of the power system. This paper proposes a two-stage planning method for distributed
generation and energy storage systems that considers the hierarchical partitioning of source-storage-load.
Firstly, an electrical distance structural index that comprehensively considers active power output and reactive
power output is proposed to divide the distributed generation voltage regulation domain and determine the
access location and number of distributed power sources. Secondly, a two-stage planning is carried out based on
the zoning results. In the phase 1 distribution network-zoning optimization layer, the network loss is
minimized so that the node voltage in the area does not exceed the limit, and the distributed generation
configuration results are initially determined; in phase 2, the partition-node optimization layer is planned with
the goal of economic optimization, and the distance-based improved ant lion algorithm is used to solve the
problem to obtain the optimal distributed generation and energy storage system configuration. Finally, the
IEEE33 node system was used for simulation. The results showed that the voltage quality was significantly
improved after optimization, and the overall revenue increased by about 20.6%, verifying the effectiveness
of the two-stage planning.},
