本研究利用LSTM网络预测利比亚鲁班市2025年的电力负荷、发电和短缺,通过整合温度和湿度等外生因素,提高预测鲁棒性,为电网稳定和能源规划提供数据驱动的决策支持。

摘要:

准确的电力预测对于电网稳定和能源规划至关重要,特别是在利比亚班加利,那里频繁的负荷削减、发电短缺和基础设施限制仍然存在。本研究提出了一种数据驱动的方法,利用2019年(一个不稳定的年份)和2023年(一个更稳定的年份)的历史数据,预测2025年的电力负荷、发电量和短缺。应用了多种时间序列模型,包括ARIMA、季节性ARIMA、动态回归ARIMA、指数平滑、极端梯度提升和长短期记忆(LSTM)神经网络。数据集通过缺失值填补、异常值平滑和对数变换进行增强。性能通过均方误差、均方根误差、均绝对误差和均绝对百分比误差进行评估。LSTM在模拟非平稳和季节性模式方面表现优异。这项工作的关键贡献是优化的LSTM框架,它整合了外生因素如温度和湿度,为预测多个电力指标提供了稳健的性能。这些结果为政策制定者和电网运营商提供了实用的洞察,以在数据稀缺、波动的地区实现主动负荷管理和资源规划。

英文摘要:

Accurate electricity forecasting is crucial for grid stability and energy planning, especially in Benghazi, Libya, where frequent load shedding, generation deficits, and infrastructure limitations persist. This study proposes a data-driven approach to forecast electricity load, generation, and deficits for 2025 using historical data from 2019 (a year marked by instability) and 2023 (a more stable year). Multiple time series models were applied, including ARIMA, seasonal ARIMA, dynamic regression ARIMA, exponential smoothing, extreme gradient boosting, and Long Short-Term Memory (LSTM) neural networks. The dataset was enhanced through missing value imputation, outlier smoothing, and log transformation. Performance was assessed using mean squared error, root mean squared error, mean absolute error, and mean absolute percentage error. LSTM outperformed all other models, showing strong capabilities in modeling non-stationary and seasonal patterns. A key contribution of this work is an optimized LSTM framework that integrates exogenous factors such as temperature and humidity, offering robust performance in forecasting multiple electricity indicators. These results provide practical insights for policymakers and grid operators to enable proactive load management and resource planning in data-scarce, volatile regions.
