the power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. this paper presents modeling and optimization of a photovoltaic (pv)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in rafsanjan, iran. for this location, different hybrid systems are studied and ...

PV Hybrid system performance is closely tied to the control strategy employed. To develop integrated optimal control strategies, a better understanding of component and system behaviour is required. Natural Resources Canada has developed a comprehensive set of PV component models for system simulation, called PV Toolbox. These models will help researchers find ways to reduce the life-cycle cost...

The stand-alone energy system having a photovoltaic (PV) panels or wind turbines have low reliability and high cost as compared with wind/PV hybrid energy system. In this study, Biogeography Based Optimization (BBO) algorithm is developed for the prediction of the optimal sizing coefficient of wind/ PV hybrid energy system in remote areas. BBO algorithm is used to evaluate optimal component siz...

The main objective of this work is to design an optimal—efficient economic power renewable energy system that feeds the required electric load of a small scale brackish reverse osmosis desalination unit and a tourism motel located in Hurghada, Egypt. Four renewable energy power systems are presented in this paper to select the most optimum one of them. These suggested renewable energy systems a...

Because photovoltaic (PV) and wind energies are renewable and free from greenhouse gas, they can be alternatives to fossil fuels. So far, many researchers have cost-optimally designed hybrid PV-wind systems. However, they have seldom provided whole datasets for other researchers to fully understand their approaches and to tackle the same problemwith their novel techniques. Thus, this study show...

The 2B proteins of coxsackievirus and poliovirus (PV) share significant structural similarity and exhibit similar biochemical activities, namely inhibition of protein secretion and modification of membrane permeability. Both proteins contain two hydrophobic domains in the carboxy-terminal two-thirds of their sequence, of which one has the potential to form a cationic amphipathic alpha-helix. To...

BACKGROUND Pulmonary vein (PV) isolation is commonly performed in patients with drug-refractory atrial fibrillation (AF) and in cases of unsuccessful ablation, antiarrhythmic agents that were ineffective before the ablation sometimes become effective afterward. Therefore, the effects and mechanisms of hybrid therapy with pilsicainide and PV isolation for AF were assessed in the present study. ...

The objective of this contribution is to present a new numerical approach for a complete design, optimum sizing, cost estimation (capital & $/kWh) and also evaluating the performance of solar photovoltaic/battery/diesel hybrid power systems. The world-wide demand for solar photovoltaic energy systems has grown steadily over the past 15 years. The need for reliable and low cost electric power in...

Hybrid PV/Wind power system can be used to generate electricity consumed in household. This paper presents the design of a stand-alone Hybrid PV/Wind energy system for a household in University of Nigeria, Nsukka (UNN) in Eastern Nigeria with a daily load of 5.2kwh/d. Solar and wind resources for the design of the system were obtained from the NASA Surface Meteorology and solar energy website a...

In this paper, life cycle cost analysis of a self sustained hybrid photovoltaic/thermal (PV/T) greenhouse dryer has been carried out. The hybrid PV/T integrated greenhouse (roof type even span) dryer, designed and constructed at Solar Energy Park, Indian Institute of Technology, New Delhi (28 0 35 N, 77 0 12 E, 216 m above MSL), India, has been used to dry Thompson seedless grapes under forced ...
