Large-scale distribution network load data cleaning research based on improved random forest

Abstract

Some large-scale distribution network load data cleaning methods have the problem of excessive relative error. A load data cleaning method for large-scale distribution network based on improved random forest is designed. Based on the release characteristics of electrical loads, large-scale distribution network open source data is collected, and an anomaly data processing model is constructed based on improved random forests to describe the processing process of numerical error data, using the original sample set as a classifier and optimising the load data cleaning model. Test results: The mean relative errors of the large-scale distribution network load data cleaning method in this paper and the other two large-scale distribution network load data cleaning methods are 3.618%, 5.162% and 5.007% respectively, indicating that the performance of the designed large-scale distribution network load data cleaning method is better after incorporating the improved random forest algorithm.
