Summary

Food warehouses and cold rooms have a significant potential for Demand Response (DR) application (stopping or reducing the power of fans and compressors of the refrigeration system) due to thermal inertia of food products. However, as air and food temperature might increase beyond acceptable limits during DR periods, DR needs to be carefully applied in order to respect the food temperature regulation and to maintain quality and safety of the products. It is thus important to predict the system behaviour in case of DR application in order to evaluate its potential impacts and to decide if DR can be performed or not. Four deep learning artificial neural networks (ANN) models, traditional Long Short-Term Memory LSTM, stacked LSTM, bidirectional LSTM and convolutional LSTM, were developed to predict future temperature and power demand perturbations due to the application of DR in cold storage. The aims of this work are: first, to assess the performance of those models in predicting the system behaviours, in particular the sudden variations during and after DR applications, and second, to identify the impact of data availability (number of sensors, their positions) and data characteristic (quality, quantity and DR patterns) on the prediction performance. The results have shown the high potential of deep learning ANN models in supporting DR application in cold storage.
