Research on Electric Vehicle Charging Load Forecasting Based on IDBO-SVM
摘要
The randomness and uncertainty of electric vehicle (EV) users’ charging behavior pose significant challenges to the prediction of EV charging load and the stable operation of the power grid. There is a problem of the influence of multiple factors, and so a prediction method of charging load of electric vehicle charging stations based on an improved dung beetle algorithm-support vector machine (IDBO-SVM) model is proposed. Firstly, the dung beetle algorithm is optimized by introducing Chebyshev chaotic mapping, the golden sine algorithm, and dynamically updated position weight coefficients. The advantages of the IDBO algorithm are validated using six test functions. Next, a feature input matrix is constructed using influencing factors such as holidays, weather conditions, and electricity prices, along with historical load data, to build the IDBO-SVM model. Finally, based on the actual charging load data from multiple EV charging stations in Nanchong city, Sichuan province, China, simulation experiments are conducted to compare and validate the accuracy and effectiveness of the model.
