 Predicting the total energy load is extremely important for all elements of the energy system for a number of reasons. This is even more pronounced when energy system includes a significant number of volatile renewable sources. This paper examines the ability of the Time-Delay Neural Network model to predict total energy load, on an hourly ba...
