摘要
En 中文
With the increasing deployment of demand response (DR), accurate short-term load forecasting (STLF) is playing an essential role in smart grid operation. This paper addressed the task of improving the accuracy of STLF using a two-stage approach, which adopts the results of traditional algorithms as baselines. The target DR deviation sequence is constructed by the mode decomposition and reorganization of the initial prediction deviation. In the above process, the deviation sequences caused by DR are obtained using dynamic mode decomposition (DMD), where the Hankel matrix is constructed to simplify the process. The final forecast accuracy is improved by su- perposing the results from traditional algorithms and the obtained deviation sequence. Multiple case studies on the data from DR pilot areas and comparison with existing models show that demand response deviation correction based on existing algorithms effectively improves power load forecasting accuracy and has good generalization.
