基于自组织映射-前馈神经网络和先知混合模型的短期负荷预测
Short-term Load Forecasting Based on SOM-BP and Prophet Hybrid Model
摘要
Abstract
To improve the accuracy of short-term load fore-casting in power system,fully exploit the multi-dimensional in-formation in the historical data to better overcome the adverse effects caused by the lack of the historical data,a short-term load forecasting method based on the self-organizing maps and back propagation(abbr.SOM-BP)and Prophet hybrid model was proposed.Firstly,the similar day set was obtained by clus-tering the historical non-power data through SOM neural net-work,and then the BP neural network was trained with the sim-ilar day data to obtain the single point load value prediction res-ults.Secondly,focusing on the periodicity and temporal trends of historical data,the Prophet temporal model was used to per-form periodic nonlinear fitting on historical load data.Through historical data fitting error feedback,the key hyperparameters of the optimization model was adjust,and finally the short-term load forecasting results based on the combination of error recip-rocal method were obtained.Finally,Taking the power load data of a certain region as an example for verification,the res-ults show that the proposed improved prediction model has higher prediction accuracy and advantages in overcoming his-torical data deficiencies and fitting non-working day load curves.关键词
