Short term electricity load forecasting for institutional buildings
Yunsun Kim,Heung-gu Son,Sahm Kim +2 more
TL;DR: In this paper, the authors presented a study forecasting peak load demand for an institutional building in Seoul, where ARIMA models, GARCH models, multiple seasonal exponential smoothing, and ANN models are used.
Journal ArticleDOI
Forecasting Charging Demand of Electric Vehicles Using Time-Series Models
Yunsun Kim,Sahm Kim +1 more
TL;DR: This study compared the methods used to forecast increases in power consumption caused by the rising popularity of electric vehicles (EVs) using trigonometric exponential smoothing state space, autoregressive integrated moving average, artificial neural networks (ANN), and long short-term memory (LSTM) modeling, based on past values and exogenous variables.
Journal ArticleDOI
Time Series Clustering of Electricity Demand for Industrial Areas on Smart Grid
Heung-gu Son,Yunsun Kim,Sahm Kim +2 more
TL;DR: In this paper, the authors present a prediction method that uses a combination of forecasting values based on time-series clustering, such as Trigonometrical transformation, Box-Cox transformation, autoregressive moving average (ARMA) errors, trend and seasonal components (TBATS), double seasonal Holt-Winters (DSHW), fractional auto-gressive integrated moving average, ARIMA with regression (Reg-ARIMA), and neural network nonlinear autoregression (NN-AR) are used for demand forecasting based on clustering.
Journal ArticleDOI
Electricity Load and Internet Traffic Forecasting Using Vector Autoregressive Models
Yunsun Kim,Sahm Kim +1 more
TL;DR: In this paper, the applicability of measuring internet traffic as an input of short-term electricity demand forecasts was investigated, and it was found that Internet traffic can be a useful variable in certain models and can increase prediction accuracy when compared to models in which it is not a variable.
Journal ArticleDOI
Linear time-varying regression with copula–DCC–asymmetric–GARCH models for volatility: the co-movement between industrial electricity demand and financial factors
TL;DR: In this article , the authors examined the dependence structure of industrial electricity demand and financial indicators using the copula dynamic conditional correlation with symmetric and asymmetric generalized autoregressive conditional heteroscedasticity (GARCH) models to forecast volatility.
