The price changes in the electricity market will adversely affect the utility revenue and user cost. The current electricity price forecasting method has a low degree of utilization of its periodic variation law and a short forecast step size, which makes the electricity price forecast have large errors. A two-way LSTM model based on ELU activation function is proposed to predict the short-term electricity price change on the supply side of the power market. The gradient disappearance problem in the back propagation calculation process is optimized by ELU, and the accuracy of electricity price prediction is improved. Experiments on models and algorithms in the electricity price database of the PJM power market in the United States show that compared with the ARIMA and ARMA models, the proposed model has higher accuracy, and the algorithm converges to a lower loss rate, which can provide greater fluctuations in the supply side of the power market. The electricity price is accurately predicted.
