Distribution Network Planning Load Forecasting Analysis Based on Improved Grey Model
In order to further improve the level of medium and long term load forecasting in distribution network planning,an improved grey forecasting model was proposed.By analyzing the characteristics of the original data,multiple modeling data sets are obtained,and multiple GM(1,1)models are constructed,and the variation characteristics of load data are characterized jointly by multiple models.The modeling results of actual data show that the model has good prediction accuracy.At the same time,compared with the traditional grey model,linear regression model and quadratic regression model,the model has the smallest error of load forecasting,and can achieve a better forecasting effect.This research can effectively improve the level of load forecasting in power system planning.
