With grid expansion in China, many metropolitan power grids have been divided into partitions at 220kV to reduce the system short-circuit current and make the grid structure clearer. However, there are still a lot of problems with the current domestic (Chinese) grid partitioning. In contrast, urban power grids of developed countries are fully developed, and their partition operation experience can be reference for domestic urban power grids. In this paper, the grid partitioning situation of

Then, similar work is done to analyze the grid partition status quo of New York and Tokyo of which grid partition features are prominent. Finally, the metropolitan power grid partition situation in China and abroad is comparatively analyzed to provide reference for the Chinese urban power grids.
