Abstract: Aiming at the problems of low-prediction accuracy and long prediction time in traditional energy market demand prediction methods, an energy market demand prediction method based on grey BP-NN optimisation combination is proposed. The influencing factors of energy market demand are analysed through economic growth factors, energy price factors, industrial structure factors, population and urbanisation factors and environmental policy factors, the analysis sequence is determined, the analysis matrix is constructed, the grey correlation degree of each influencing factor is calculated and the mean value is standardised. According to the processing results, the energy market demand prediction model of grey theory is constructed. Taking the prediction results of grey model and factors affecting energy demand as the input of BP neural network, an improved BP neural network structure is constructed and the prediction results are output. The simulation results show that the proposed method has high accuracy and short prediction time.
