Predictive Modeling of Photovoltaic Energy Yield Using an ARIMA Approach

Applied Sciences
This paper presents a method for predicting the energy yield of a photovoltaic (PV) system based on the ARIMA algorithm. We analyze two key time series: the specific yield and the total yield of the PV system. Two ARIMA models are developed for each time

Energies of Fröhlich surface optical phonon in Q1D nanostructures: Curvature and dielectric effects

AIP Advances
Energy of Fröhlich surface optical (SO) phonon in quasi-one-dimensional (Q1D) nanostructures remains doubtful in terms of Raman and photoluminescence experimental data. Based on a notion of the curvature proposed, the confusion is clearly clarified.

Evaluating the Effectiveness of VFD Retrofit Under Operational and Manual Control Constraints in a Kenyan Petroleum Depot

Energies
Globally, downstream petroleum operations face increasing pressure to optimize energy use and reduce carbon emissions, with electrically driven pumping systems representing the dominant site-level electricity load. This study investigates why anticipated

Time Series Analysis Intervals and Energy Economics Forecast

, 2014
Ce document de travail présente les méthodes d’estimation des paramètres d’un modèle de régression lorsque les variables sont observées sous un format intervalle. Il illustre cette procédure d’estimation sur les données de consommation d’électricité en France, afin d’effectuer une comparaison entre les valeurs prévisionnelles issues des données ...
