摘要
建筑电力负荷预测技术可用于辅助区域建筑能源规划、能耗及碳排放计算等。本文探索了机器学习算法在区域电力负荷短期预测方面的应用,使用了5种机器学习算法对北京某区域建筑的日电力负荷进行了预测,结果显示XGBoost(极限梯度提升)和LSTM(长短期记忆)2种先进的学习算法可以提供较为精准的预测结果。进一步,考虑到天气预报的不确定性,我们选取这2种模型讨论了输入不确定性对电力负荷预测结果的影响,结果表明使用LSTM模型可以有效降低由于天气预报不稳定性引起的预测误差,更适用于开展电力负荷短期预测。
The building power load forecasting technology can be used to assist in regional building energy planning,energy consumption,and carbon emission calculations.This paper explored the application of machine learning algorithms in short-term prediction of regional power loads.Five machine learning algorithms were used to predict the daily power loads of a building in Beijing.The results showed that XGBoost(Extreme Gradient Boosting)and LSTM(Long Short-Term Memory)advanced learning algorithms can provide more accurate prediction results.Furthermore,considering the uncertainty of weather forecasts,we selected these two models to discuss the impacts of input uncertainty on the results of power load forecasting.The results indicated that the LSTM model can effectively reduce prediction errors caused by weather forecast instability and is more suitable for short-term power load forecasting.
