Power system prediction method and device and storage medium

The invention provides a power system prediction method and device and a storage medium, and relates to the technical field of power systems, and the power system prediction method comprises the steps: obtaining short-term original data and long-term original data; cleaning the short-term original data and the long-term original data to obtain short-term prediction data and long-term prediction data; inputting the short-term prediction data into a trained LSTM model to obtain a first prediction result; inputting the short-term prediction data into a trained ARIMA model to obtain a second prediction result; performing unequal weight combination on the first prediction result and the second prediction result to obtain a short-term prediction result; and inputting the long-term prediction data into a trained TiDE model to obtain a long-term prediction result. According to the invention, through the trained LSTM model, ARIMA model and TiDE model, an accurate short-term prediction result and a long-term prediction
