“…Today wind energy is the least expensive option but requires more maintenance, and is space consuming compared to photo-voltaic solar panels which however, are currently more expensive. Note that the forecasts in price reduction are promising though, as shown in Figure 1 [2]. This indicates that taking into account forecast measurements is a strong element of effective decision making.…”

“…It can be estimated with existing forecasting curves of market and demographic studies. It is expected as shown in Figure 1, that the cost for renewable energy technologies will decrease in the coming years [2]. For each type of uncertainty, the current approach considers an annual growth rate for the electricity demand (that can be tuned by the end-user), and a total future cost per potential park according to the technology used and its transportation cost.…”

RésuméLa recherche appliquée enénergies renouvelables soulève des défis complexes de nature technologique, economique ou politique. Dans cet article, nous adressons le problème technico-économique de sélection optimale d'emplacements de parcséoliens et solaires en Egypte, de telle sorte que la demande enélectricité soit satisfaiteà coût minimum. Ultimement, notre objectif est de construire un outil d'aideà la décision qui va pourvoir aux investisseurs privés et gouvernementaux, une aide précieuse pour prendre des décisionsà court et long terme relativementà la création de tels parcs. Les approches existantes raisonnent essentiellementà partir de données passées. Dans cet article, nous introduisons une nouvelle approche qui considèreà la fois les données passées et futures, et montrons l'impact de la prise en compte des deux types de données dans une modèle d'optimisation en deux temps. Nous montrons que la Programmation Linéaire par Entiers est une mé-thode efficace pour résoudre le problème avec des données passées ainsi que le modèle en deux temps qui prend en compte les données prédites, rajoutant de nouvelles contraintes au modèle initial. Notreévaluation montre que le modèle en deux temps améliore la solution avec une vision plus globale et un meilleur coût total.

“…The selecting of carrier ratio N Since the fundamental wave of the inverter circuit output line phase voltage and the phase of the modulated wave is same, line voltage and the voltage is30 difference, so the carrier ratio N should be an integer multiple of 3 [4], so ensures the symmetry of the output waveform . N is typically an odd number, to avoid even harmonics.…”

Abstract. Based on the Z source inverters operating characteristics studied, and has carried out harmonic analysis by simulation of its output voltage. Through the reasonable design of carrier frequency, filter design and triple frequency harmonic injection method to suppress the output voltage harmonic, the Z source inverter is simulated by SIMULINK. Through the analysis of the THD of output voltage, the method of Z source inverter output voltage harmonic s with good inhibitory effect.

In this study, an energy harvester using the mechanical vibrations created by the airflow on piezoelectric transducers outside a vehicle was designed, produced and introduced. The introduced harvester has an energy production potential of μJ level. Given an energy power, very little power but long-term harvest was achieved. While the introduced vehicle was driven at speeds of 70, 90, and 110 km/h, energy production at location angles of 0 , 45 , and 90 was determined for each speed. Vehicle speed, location angle, airflow outside the vehicle, and harvester output were measured. Output voltage of the harvester was found to be directly proportional to vehicle speed. Output of the transducers was combined using a circuit topology that would maximize the output voltage. Thanks to this circuit highest output voltage was obtained from the location angle of 0. Thus, maximum output power was obtained at a speed of 110 km/h for 0 location angle. This research develops a new design method for efficient and practical energy generated by piezoelectric sensors placed on a vehicle from the vibration of the airflow around a moving vehicle. This energy harvester can meet the internal micro energy needs of the vehicle with an external battery.
