Research on Peak Load Prediction of Distribution Network Lines Based on Prophet-LSTM Model

Abstract

The increasing demand for precise load forecasting for distribution networks has become a crucial requirement due to the continual surge in power consumption. Accurate forecasting of peak loads for distribution networks is paramount to ensure that power grids operate smoothly and to optimize their configuration. Many load forecasting methods do not meet the requirements for accurate data and trend fitting. To address these issues, this paper presents a novel forecasting model called Prophet-LSTM, which combines the strengths of the Prophet model’s high trend fitting and LSTM model’s high prediction accuracy, resulting in improved accuracy and effectiveness of peak load forecasting. The proposed algorithm models the distribution network peak load using the Prophet-LSTM algorithm. The researchers then analyzed the experimental data and model of the algorithm to evaluate its effectiveness. We found that the Prophet-LSTM algorithm outperformed the Prophet and LSTM models individually in peak load prediction. We evaluate the proposed model against commonly used forecasting models using MAE (mean absolute error) and RMSE (root mean square error) as evaluation metrics. The results indicate that the proposed model has better forecasting accuracy and stability. As a result, it can predict the peak load of distribution networks more accurately. In conclusion, this study offers a valuable contribution to load forecasting for distribution networks. The proposed Prophet-LSTM algorithm provides a more precise and stable prediction, making it a promising approach for future applications in distribution network load forecasting.

Short-Term Load Forecasting of Electric Vehicle Charging Stations Accounting for Multifactor IDBO Hybrid Models

“…Data-driven methods mainly use artificial intelligence algorithms for charging load prediction. Traditional AI algorithms such as random forest (RF) [26], support vector machine (SVM) [27], and XGBoost [28], although they have good non-linear data fitting ability and parameter learning ability, they are unable to learn the temporal features in the time-series data similar to the charging load historical data well. The development of deep learning [29] provides new methods for EV charging load prediction.…”

Deep Learning Model Performance and Optimal Model Study for Hourly Fine Power Consumption Prediction

“…In many previous studies, research on deep learning models for power usage prediction was conducted. However, many studies have not made detailed predictions of power consumption by time, such as predicting power consumption after 1 h or additionally predicting power consumption after 5 h or 10 h [12][13][14][15]. Fine-grained power usage forecasts offer detailed insights into power consumption patterns throughout the day, enabling better understanding of how the demand fluctuates at different times.…”
