A method and device for determining the nature of electric loads based on grid graph topology calculation

Abstract

The present invention provides a method and device for determining the properties of electric loads based on grid graph topology calculation, wherein the method includes: traversing the grid graph topology of the target area, determining one or more target distribution transformers in the target area; associating with the target The marketing station corresponding to the distribution transformer obtains the load characteristic curve of the user connected to the target distribution transformer; clusters the users according to the load characteristic curve to obtain multiple clusters; compares the cluster center load characteristic curve of each cluster with the Each load characteristic curve in the target classification template is clustered, and the load properties corresponding to the users in each cluster are determined according to the clustering results. The template library includes a variety of classification templates, and the classification standards of each classification template are different. It includes a variety of load characteristic curves, and each load characteristic curve corresponds to different load properties. Through the implementation of the invention, the complete reflection of the load characteristics and the accurate clustering of the users are guaranteed, and the self-defined division is carried out according to the actual needs.

Description

technical field [0001] The invention relates to the field of electric power systems, in particular to a method and device for determining the properties of electric loads based on network graph topology calculations. Background technique [0002] In the current power system, there is information isolation between the power supply side responsible for power supply and the user side receiving power. Power management managers obtain power supply load data through substations of various voltage levels. The minimum sensing unit of the main network is only 10kV feeder, and the main network Only the distribution transformer can be sensed, and the users connected to each distribution transformer cannot be sensed. Therefore, when establishing a power customer account on the side of the 10kV distribution network, it is necessary to obtain the load nature of the specific user through the relationship between the user-transformer household transformer, and through the user-transformer re...
