Abstract

The integration of renewable energy sources has resulted in an increasing intricacy in the functioning and organization of power systems. Accurate load forecasting, particularly taking into account dynamic factors like as climatic and socioeconomic impacts, is essential for effective management. Conventional statistical analysis and machine learning methods struggle with accurately capturing the intricate temporal relationships present in load data. Recurrent neural networks (RNNs), specifically long short-term memory (LSTM) networks, demonstrate potential in representing and interpreting sequences of data. This study presents an approach that employs an LSTM-RNN model for load forecast prediction. This study highlights the importance of this technology in combining effective demand response with distributed renewable energy sources, which are crucial for the stability of smart grids and accurate power demand estimation. The LSTM-RNN model has outstanding accuracy, with a Mean Absolute Percentage Error (MAPE) of 1.5% and a Root Mean Squared Error (RMSE) of 26.5 for hourly forecasts. Additionally, it achieves a MAPE of 1.77% and an RMSE of 30 for yearly load estimations. The hourly LSTM-RNN load forecast model outperforms the yearly LSTM-RNN load forecast model, as evidenced by lower error rates. Importantly, this model demonstrates robustness even when the inputs are inadequate or noisy. To summarize, this research suggests that LSTM-RNN is a practical and efficient approach for precisely forecasting load in power systems. This underscores its capacity to enhance operational efficiency and resilience in power systems.

摘要

可再生能源的整合导致电力系统的运行和组织日益复杂。准确的负荷预测,特别是考虑到气候和社会经济影响等动态因素,对于有效管理至关重要。传统的统计分析和机器学习方法难以准确捕捉负荷数据中存在的复杂时间关系。循环神经网络(RNN),特别是长短期记忆(LSTM)网络,在表示和解释数据序列方面显示出潜力。本研究提出了一种采用LSTM-RNN模型进行负荷预测的方法。本研究强调了该技术在将有效的需求响应与分布式可再生能源相结合方面的重要性,这对于智能电网的稳定性和准确的电力需求估计至关重要。LSTM-RNN模型具有出色的准确性,每小时预测的平均绝对百分比误差(MAPE)为1.5%,均方根误差(RMSE)为26.5。此外,其年度负荷估计的MAPE为1.77%,RMSE为30。每小时的LSTM-RNN负荷预测模型优于年度LSTM-RNN负荷预测模型,误差率更低证明了这一点。重要的是,即使输入不充分或有噪声,该模型也表现出鲁棒性。总之,本研究表明LSTM-RNN是一种精确预测电力系统负荷的实用且高效的方法。这突出了其提高电力系统运行效率和恢复力的能力。
