Aiming at the problem of short-term heating load control prediction,a prediction model based on improved slime mould algorithm(ISMA)was proposed to optimize bidirectional long short term memory(BiLSTM).The slime mould algorithm was improved by using improved strategies such as cat mapping,T-distribution variation and stochastic reverse learning,and the improved slime mould algorithm optimized the parameters of BiLSTM network.The ISMA-BiLSTM model was constructed to predict the heating load of heat exchange station.Experimental results show that the prediction results of the as-proposed model are more reasonable and the prediction accuracy is improved to some extent,compared with SMA-BiLSTM,BiLSTM and LSTM models,so the ISMA-BiLSTM model can meet the needs of actual engineering control in short-term heating load prediction.
