Abstract: ABSTRACT: Under the goal of "carbon peaking and carbon neutrality", large-scale new energy sources are connected to the grid, and the proportion of new sources and loads continues to increase, and its uncertainty has brought great challenges to the balance of power supply and demand. In the past two years, there has been a general shortage of power supply in my country. With the continuous growth of load and the enhancement of controllability, it is urgent to expand load-side control resources to achieve a balance between power supply and demand. Starting from the demand of precise load control, this paper elaborates the load clustering method considering different attributes, and proposes a precise load shedding allocation algorithm according to priority, proportion and multi-dimensional attributes, which lays the foundation for the formulation of precise load shedding control master station strategy. It also provides technical support for ensuring people's livelihood.。
