Power quality and energy consumption prediction model of transmission line based on grey multiple linear regression

Abstract

Power quality and energy consumption management is one of the key tasks of power grid companies. With the increasingly prominent power quality problems, it is necessary to study the additional losses caused by power quality problems on transmission lines. Therefore, the power quality and energy consumption prediction model of transmission lines based on grey multiple linear regression is constructed. The power quality and energy consumption prediction data of transmission lines are processed under the grey multiple linear regression, the characteristic attributes between samples are calculated, and the weight value of the characteristic attributes is obtained. The characteristic attributes of the calculation results are input into the grey multiple linear regression network, the power quality energy consumption prediction results of the transmission line are output, and the construction of the power quality energy consumption prediction model is completed. The experimental results show that the energy consumption prediction curve obtained by the model is consistent with the actual energy consumption curve, and the energy consumption in summer is generally higher than that in winter. Based on this result, we can effectively establish the demand response of the transmission line with a good prediction effect.
