研究目的
To propose and apply a hybrid deep learning model (LSTM-Convolutional Network) for accurate photovoltaic power prediction, addressing the challenge of integrating volatile and intermittent solar energy into existing energy systems.
研究成果
The LSTM-CNN hybrid model demonstrates superior performance in photovoltaic power forecasting by effectively extracting temporal and spatial features of the data. It outperforms both single models and the CNN-LSTM hybrid model in accuracy, as evidenced by lower MAE, RMSE, MAPE, and SDE values. The study highlights the importance of the sequence in feature extraction (temporal before spatial) for optimal performance.
研究不足
The hybrid model requires longer training and running times compared to single models, which may be a constraint in practical applications despite its higher accuracy.
1:Experimental Design and Method Selection:
The study employs a hybrid deep learning model combining LSTM for temporal feature extraction and CNN for spatial feature extraction.
2:Sample Selection and Data Sources:
Utilizes 1B DKASC, Alice Springs PV system data, including current phase average, active power, wind speed, weather temperature, etc., with a resolution of 5-minutes over half a year.
3:List of Experimental Equipment and Materials:
The simulation is conducted on a personal computer with Python
4:6, 64-bit operating system, 00 GB of RAM, and Intel(R) Core (7M) i5-8400 CPU@8GHZ 81GHZ. Experimental Procedures and Operational Workflow:
The LSTM model extracts temporal features first, followed by the CNN model extracting spatial features, with dropout layers added to prevent overfitting.
5:Data Analysis Methods:
The performance is evaluated using MAE, MAPE, RMSE, and SDE metrics, comparing the hybrid model against single models (LSTM, CNN) and another hybrid model (CNN-LSTM).
