论文摘要
公用事业公司面临的主要挑战之一是通过最少的温室气体排放量确保有效供应。智能电表和智能电网的出现在通过主动的预测等主动技术(例如预测)实现了优化的热能供应方面,为实现热能的供应提供了前所未有的优势。在本文中,我们提出了一个基于神经网络的热量需求的预测框架,在该框架中,时间序列被编码为具有嵌入外源变量(例如天气和假日/非假日)的能力的缩放图。随后,使用CNN来预测前方的热负荷多步。最后,将提出的框架与其他最新方法(例如Sarimax和LSTM)进行了比较。回顾性实验的定量结果表明,所提出的框架始终优于最先进的基线方法,而从丹麦获得的现实世界数据。与所有其他方法相比,使用建议的框架实现了MAPE的最小平均误差为7.54%,而RMSE的平均误差为417kW。
One of the primal challenges faced by utility companies is ensuring efficient supply with minimal greenhouse gas emissions. The advent of smart meters and smart grids provide an unprecedented advantage in realizing an optimised supply of thermal energies through proactive techniques such as load forecasting. In this paper, we propose a forecasting framework for heat demand based on neural networks where the time series are encoded as scalograms equipped with the capacity of embedding exogenous variables such as weather, and holiday/non-holiday. Subsequently, CNNs are utilized to predict the heat load multi-step ahead. Finally, the proposed framework is compared with other state-of-the-art methods, such as SARIMAX and LSTM. The quantitative results from retrospective experiments show that the proposed framework consistently outperforms the state-of-the-art baseline method with real-world data acquired from Denmark. A minimal mean error of 7.54% for MAPE and 417kW for RMSE is achieved with the proposed framework in comparison to all other methods.
