Electricity demand prediction accuracy is crucial for operational energy resource management and strategy. In this study, we provide a multi-form model for electricity demand prediction in China that based on incorporating of an upgraded Support Vector Machine (SVM) and a Boosted Multi-Verse Optimizer (BMVO). The suggested model is proposed to address the shortcomings of existing prediction approaches, which frequently fail to internment the complicated nonlinear interactions between demand for electricity and the variables that influence it. The improved SVM algorithm incorporates a modified genetic algorithm based on kernel function for enhancing the stability of the model. The BMVO technique is employed to optimize the combined model's weights and increase its generalization effectiveness. The suggested approach is tested by real-world Chinese energy demand data. The findings show that it outperforms existing prediction approaches in terms of reliability and precision. Further, the number of samples chosen affects how well the proposed BMVO linked with the Incremental SVM (ISVM) predicts outcomes. Particularly, when 1735 samples are chosen, the lowest level of Mean Absolute Percent Error (MAPE) was noted. The Root Mean Square Error (RMSE) and MAPE values under the proposed BMVO/ISVM model are reduced by 53.72% and 55.22%, respectively, compared to the Artificial Neural Network (ANN) approach reported in literature. Finally, the suggested model is capable of accurately predicting the electricity demand in China and has the potential to be applied to other energy-demand prediction applications.
电力需求预测的准确性对于运营能源资源管理和战略至关重要。在本研究中,我们基于整合升级后的支持向量机(SVM)和增强型多宇宙优化器(BMVO),为中国的电力需求预测提供了一种多形式模型。所提出的模型旨在解决现有预测方法的缺点,这些方法常常无法捕捉电力需求与影响它的变量之间复杂的非线性相互作用。改进后的支持向量机算法纳入了基于核函数的改进遗传算法,以增强模型的稳定性。采用BMVO技术来优化组合模型的权重并提高其泛化效果。所建议的方法通过中国实际能源需求数据进行测试。结果表明,在可靠性和精度方面,它优于现有预测方法。此外,所选样本数量会影响所提出的BMVO与增量支持向量机(ISVM)相结合预测结果的效果。特别是,当选择1735个样本时,平均绝对百分比误差(MAPE)达到最低水平。与文献中报道的人工神经网络(ANN)方法相比,所提出的BMVO/ISVM模型下的均方根误差(RMSE)和MAPE值分别降低了53.72%和55.22%。最后,所建议的模型能够准确预测中国的电力需求,并有可能应用于其他能源需求预测应用中。
