Home Load Disaggregation using Deep Learning and Bayesian Optimization: A Case Study in Arctic Climate in Northern Norway
Sammendrag
Load monitoring is an essential task in energy management systems. In this paper, an approach that relies on a long short-term memory (LSTM) model and a discrete wavelet transform (DWT) filter is presented to estimate the energy usage of flexible appliances. In the preprocessing stage, the main features of the aggregated power signal are extracted using DWT. Deep learning methods are very sensitive to hyperparameters, and choosing optimal values can significantly improve the accuracy of the model. To optimize the performance of the LSTM model, a Bayesian optimization algorithm is used to find the optimal set of hyperparameters. The performance of the proposed approach is evaluated using real-world data collected from a residential building in northern Norway. The results show that the proposed methodology can accurately disaggregate the power consumption of different appliances, with higher accuracy compared to existing methods.
