Abstract Accurately forecasting annual electricity consumption of regional power grid has important practical significance for the local grid development and power supply. Using grey theory in the paper, discussing the original data pretreatment technology, considering the new variation trend of system in the influence of the latest information, equal dimension addition and dynamic update of forecasting information is realized, and grey prediction model of equal dimension new information addition of power consumption is built. Based on Matlab platform, the actual electric quantity of regional grid is predicted by modeling, and the example proves that the method is feasible and has certain practical value.
