Accurately modelling and forecasting electricity consumption remains a challenging task due to the large number of statistical properties that characterize this time series such as seasonality, trend, sudden changes, slow decay autocrrelation function, among many others. This study contributes literature by using comparing four advanced econometrics models, machine learning deep models1 analyze forecast during COVID-19 pre-lockdown, lockdown, releasing-lockdown, post-lockdown phases. Monthly data on Qatar's total has been used from January 2010 December 2021. The empirical findings demonstrate both econometric models are able capture most important features characterizing consumption. In particular, it is found climate change based factors, e.g temperature, rainfall, mean sea-level pressure wind speed, key determinants terms forecasting, results indicate autoregressive fractionally integrated moving average three state markov switching with exogenous variables outperform all other models. Policy implications energy-environmental recommendations proposed discussed.

The study presents a novel framework integrating feature selection (FS) and machine learning (ML) techniques to forecast inland national energy consumption (EC) in the United Kingdom across all sources. This innovative strategically combines three FS approaches with five interpretable ML models using Shapley Additive Explanations (SHAP), dual goal of enhancing accuracy transparency EC predictions. By meticulously selecting most pertinent features from diverse features—including meteorological conditions, socioeconomic parameters, historical patterns different primary fuels—the proposed enhances robustness forecasting model. is achieved through benchmarking approaches: ensemble filter, wrapper, hybrid filter-wrapper. In addition, we introduce filter FS, synthesizing outcomes multiple base methods make well-informed decisions about retention. Experimental results underscore efficacy both wrapper filter-wrapper models, ensuring process remains comprehensible while utilizing manageable number (four eight). experimental indicate that subsets are usually selected for each combined approach not only demonstrates framework's capability provide accurate forecasts but also establishes it as valuable tool policymakers analysts.

Statistical Comparison of Time Series Models for Forecasting Brazilian Monthly Energy Demand Using Economic, Industrial, and Climatic Exogenous Variables

Applied Sciences, Год журнала: 2024, Номер 14(13), С. 5846 - 5846

Опубликована: Июль 4, 2024

Energy demand forecasting is crucial for effective resource management within the energy sector and aligned with objectives of Sustainable Development Goal 7 (SDG7). This study undertakes a comparative analysis different models to predict future trends in Brazil, improve methodologies, achieve sustainable development goals. The evaluation encompasses following models: Seasonal Autoregressive Integrated Moving Average (SARIMA), Exogenous SARIMA (SARIMAX), Facebook Prophet (FB Prophet), Holt–Winters, Trigonometric Seasonality Box–Cox transformation, ARMA errors, Trend, components (TBATS), draws attention their respective strengths limitations. Its findings reveal unique capabilities among models, excelling tracing seasonal patterns, FB demonstrating its potential applicability across various sectors, Holt–Winters adept at managing fluctuations, TBATS offering flexibility albeit requiring significant data inputs. Additionally, investigation explores effect external factors on consumption, by establishing connections through Granger causality test conducting correlation analyses. accuracy these assessed without exogenous variables, categorized as economical, industrial, climatic. Ultimately, this seeks add body knowledge prediction, well allow informed decision-making planning policymaking and, thus, make rapid progress toward SDG7 associated targets. paper concludes that, although achieves best accuracy, most fit model, considering residual autocorrelation, it predicts that Brazil will approximately 70,000 GWh 2033.
