Univariate deep learning models for short-term electricity load forecasting from renewables

Abstract

Renewable energy offers a cost-effective, carbon-free solution for energy needs, while protecting the environment. Accurate forecasting of electricity generation from renewable sources is crucial for the efficiency of modern power grids. This study employs a univariate deep learning approach to predict daily renewable energy generation, evaluating Recurrent Neural Networks (RNNs) and Convolutional Neural Networks (CNNs) as candidate models. Five performance metrics—mean absolute error, root mean squared error, mean absolute percentage error, mean absolute scaled error and the coefficient of determination—are employed to assess the forecasting power of the algorithms. The empirical results show that CNN outperforms other models, achieving an $R^2$ of almost $94\%$. This research shows that the univariate model based on historical data of electricity load generated from renewables can accurately predict day-ahead electricity load, even without meteorological data.
