[pt] INSERÇÃO DE VARIÁVEIS EXÓGENAS NO MODELO HOLT-WINTERS COM MÚLTIPLOS CICLOS PARA PREVISÃO DE DADOS DE ALTA FREQUÊNCIA OBSERVACIONAL DE DEMANDA DE ENERGIA ELÉTRICA / [en] INTRODUCE EXOGENOUS VARIABLES IN HOLT-WINTERS EXPONENTIAL SMOOTHING WITH MULTIPLE SEASONAL PATTERNS HIGH FREQUENCY ELECTRICITY DEMAND OBSERVATIONS

[pt] O objetivo deste trabalho é inserir variáveis exógenas no modelo Holt-Winters com múltiplos ciclos, genuinamente univariado. Serão usados dados horários de demanda de energia elétrica provenientes de uma cidade da região sudeste do Brasil e dados de temperatura, tanto em sua forma primitiva quanto derivada, por exemplo, indicadores de dias quentes, o chamado cooling degree days (CDD). Com isso, pretende-se melhorar o poder preditivo do modelo, gerando previsões com maior acurácia. / [en] The aim of this thesis is to insert exogenous variables in the model Holt-Winters with multiple cycles, genuinely univariate. Hourly data will be used for electricity demand from a city in southeastern Brazil and temperature data, both in its original form as derived, for example, indicators of hot days, cooling degree days called (CDD). With this, we intend to improve the predictive power of the model, generating predictions with greater accuracy.
