Abstract The short‐term load prediction is the critical operation in peak demand administration and power generation scheduling of buildings that integrated smart solar microgrid (SSM). Many research studies have proved hybrid deep learning strategies achieve more accuracy feasibility practical applications than individual algorithms. Moreover, many SSM on rooftop with battery management system (BMS) to enhance energy efficiency management. However, traditional methodologies only processed weather parameters information for prediction, ignoring collected data from BMS by advanced metering infrastructures (AMI), which probably improved accuracy. In this research, accumulated building are before methodology implementation. Considering diversities BMS, an adaptive convolution neural network long memory (CNN‐LSTM) proposed hourly electrical prediction. CNN could extract large‐scale input feature, while LSTM better accurate forecasts. Pearson correlation matrix calculated feature selection scheme different units. hyperparameter tuning utilized obtaining optimized CNN‐LSTM algorithm. K‐fold cross‐validation employed algorithm verification, includes LSTM, GRU, CNN, Bi‐LSTM methodologies. results prove achieved outperformed improvements, 20.57%, 29.63%, 19.06% MSE, MAE, MAPE, 21.24%, 22.02%, 3.82% validating respectively. combined superior predicting accuracies, proving adaptability ability integrating into (EMS) building's SSM.
