Prediction of solar energy consumption using recurrent neural networks

Predicting solar energy consumption

Single-feature and multi-feature, auto-regressive LSTM RNN vs linear regression for higly-volatile time series.

A small town in Spain is sourced by solar energy thanks to a solar plant. Over a year (2015), the plant's energy output and the town's energy consumption data were gathered; and along with it, data from a nearby meteorological station.

We then come with several models that predict the amount of energy output/consumption given a set of weather conditions. In the notebook, we employ several machine learning techniques to tackle these tasks, among which we construct Long Short-Term Memory Recurrent Neural Networks.

We try and predict with an hourly basis, then a 12-hour basis and finally with a 24-hour basis, and compare. Analizing the differences has important consequences because a model will be more or less accurate depending on the time window to predict.
