Aiming at the problem of short-term electricity price forecasting in the spot electricity market, this paper proposes a short-term electricity price forecasting algorithm based on LSTM neural network. Firstly, the algorithm constructs the electricity price correlation factor matrix, and then uses the LSTM model to forecast the electricity price. In the LSTM model, the Adam gradient descent method is used to estimate the input, forgetting and output of the LSTM model, and the node price data in the forecasting time interval are obtained. Using the PJM-RTO actual node price data of PJM website, the simulation results show that the proposed method can accurately predict the node price. Compared with the prediction interval of one week, two weeks and two months, the accuracy is the highest when the prediction interval is one month, the average absolute error percentage and average absolute error are the minimum, and the prediction effect is the best.
