Solar Radiation Forecasting Using Artificial Neural Network for Local Power Reserve
RÉSUMÉ / ABSTRACT : Renewable energy sources have a variable nature and are greatly depending on weather conditions. The load is also uncertain. Hence, it is necessary to use power reserve equipment to compensate unforeseen imbalances between production and load. However, this power reserve must be ideally minimized in order to reduce the system cost…
Statistical study of the influence of the data sampling interval on the estimation of wind turbine energy
RÉSUMÉ / ABSTRACT : Main deficiency for wind power is variability. It is really difficult to predetermine the wind’s potential since wind velocity cannot be controlled or predicted with pinpoint accuracy. In this paper, two different methods are applied in order to estimate the monthly wind energy for different sites; those estimations are done using Weibull distribution and calculating energy with…
Etude du vieillissement d’un banc de stockage plomb-acide dans un système hybride multi-sources
RÉSUMÉ / ABSTRACT : L’objectif de cet article est de présenter une méthodologie pour le calcul du taux de vieillissement d’une batterie de stockage insérée dans un système hybride multi-sources. La démarche consiste dans un premier temps à connaître les sollicitations de la batterie durant une année connaissant à chaque instant son état de charge…
Étude d’un système hybride éolien photovoltaïque avec stockage : dimensionnement et analyse du cycle de vie
RÉSUMÉ : Dans ce papier, nous présentons l’étude d’un système hybride éolien photovoltaïque avec stockage pour un habitat résidentiel de 4 personnes à La Rochelle en France. Cette étude comprend le dimensionnement du système, l’évaluation de ses performances ainsi que l’analyse économique et environnementale de son cycle de vie. Les résultats montrent un impact environnemental…
Life cycle cost, embodied energy and loss of power supply probability for the optimal design of hybrid power systems
RÉSUMÉ / ABSTRACT : Stand-alone hybrid renewable energy systems are more reliable than one-energy source systems. However, their design is crucial.For this reason, a new methodology with the aim to design an autonomous hybrid PV-wind-battery system is proposed here. Based on a triple multi-objective optimization (MOP), this methodology combines life cycle cost (LCC), embodied energy…
Dimensioning a hybrid electrification system (PV / WT / DG + battery) using a dynamic simulation
RÉSUMÉ / ABSTRACT : The aim of this paper is to demonstrate that a dynamic simulator, taking into account temporal data of renewable sources and using energy on one year, is able to sizing each element composing the electric generation system and the storage system. The electrical system includes photovoltaic panels (PV), a wind turbine…
