Method of substation differential power supply zoning based on grid division

Abstract

The conventional substation differential power supply zoning method uses the grey clustering coefficient to determine the power supply weight of each zone, which is vulnerable to the influence of the dynamic entropy value of power supply, leading to the high power supply load. Therefore, a new substation differential power supply zoning method needs to be designed based on grid division. That is, the grid division is used to predict the power supply load of substation partition, and then the differential power supply partition model of substation is constructed by combining the load characteristics complementation, thus realizing the differential power supply partition of substation. The case analysis results show that the designed substation differential power supply zoning method based on grid division has a small power supply load, which proves that the designed power supply zoning method has a good power supply effect, can reduce power supply loss, has a certain application value, and has made a certain contribution to reducing the regional power supply cost.
