Abstract:

The data of energy environment system under different time scales have different trend characteristics. Aiming at the prediction of data series with linear, nonlinear, or partially linear, partially nonlinear mixed trends, the Euler polynomial with nonlinear time disturbance parameters is constructed to flexibly characterize the complex trends of the data series, and then the adaptive multivariable grey prediction model driven by Euler polynomial is proposed. The difference and discrete forms of the model are derived based on the grey derivative information covering principle and the Euler polynomial mean value formula, and the optimization framework of Euler polynomial order and nonlinear time disturbance parameters based on the grey Wolf optimization algorithm is given. On this basis, the time response formula is solved by mathematical induction. Finally, examples of monthly PM2.5 in Beijing and annual total energy consumption in Jiangsu Province with different trend change characteristics are selected to verify the validity of the model, and then the model is applied to the quarterly electricity consumption forecast of Guangzhou. Meanwhile, the robustness and stability of the new model are verified based on Monte-Carlo simulation analysis and different proportions of training set modeling, indicating that the newly constructed multivariate grey prediction model can adaptively fit and predict data series with different trend change characteristics.
