Combination Forecasting Model for Energy Demand Considering Micro Policy

Aiming at the current problems of considering influence factors of energy demand forecasting in a single way, ignoring influence factors of macro policy and lacking in forecasting accuracy, a combined energy demand forecasting method together with grey correlation analysis and BP neural network is proposed. Firstly, the fields are divided according to the pertinence and direction of the macro policy, and then the indicators are analyzed in each field. Secondly, the grey correlation analysis method is used to calculate, sort and filter the initial indicators of the macro policy after the analysis. Finally, the selected initial indicators are used as the input of BP neural network, the neural network tools are used to achieve the purpose of energy demand forecasting, and a case simulation is performed to analyze the results of energy demand combination forecasting. The example results show that the proposed energy demand combination forecasting method focuses on the impact of macro policies, which effectively improves the forecasting accuracy and is practical and reliable.
