AI Technical Summary

Benefits of technology

In this new system that uses an algorithm for identifying loads with varying degrees of space distribution, it takes into account factors like weightiness or distance from other objects being carried around while carrying them. It then analyzes these data sources to identify specific loading patterns associated with each object's location within its own area. By doing so, we aimed at improving accuracy and reducing error rates over current methods.

Problems solved by technology

Technological Problem: Current Load Monitoring (LM) techniques have limitations due to their complexity or lack accuracy when identifying both traditional and adaptive types of loads with varying capacities. Additionally, current load models cannot accurately represent these variations over time without being complicated enough.

Embodiment Construction

[0039] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0040] According to the embodiment of the present invention, a wide-area adjustable load identification method is provided, which solves the problems of complex load identification models and large load identification errors.

[0041] Step 1, select the test load point of Taoshu Village substation, for the adjustable load k, its electricity load in time period t Can be expressed as: in, is the adjustment ratio of the adjustable load k in the period t, and the value range is 0~1; M is the adjustment depth of the adjustable load k. The characteristic parameter of the adjustable load k is h k =[Δ max.k , M k ,t adjm.k ,γ k ,γ p-v.k ,t max.k ,φ k ], k=1,......

Abstract

The invention discloses a method for identifying a wide-area adjustable load, which comprises: implementing feature extraction technology based on an adjustable load; correcting extracted characteristic parameters according to the spatial distribution characteristics of various typical loads; obtaining a mapping relation of the training membership for the component ratio of the load type based onthe calculation of the cluster center matrix and the membership; and identifying the component ratios of various typical loads of load points. The method for identifying the wide-area adjustable loadof the present invention can overcome the problems that the load adjustable characteristics cannot be extracted and the identification is difficult in the prior art, and has the advantages of good identification effect and small error.
