Photovoltaic (PV) systems are the leading solutions for reducing carbon dioxide (CO2) emissions in Iran’s energy system. However, there some challenges to investing PV Iran, such as low market price and high investment cost of systems. Although flat feed-in tariff (FiT) is defined help purchase from systems, it not attractive investors. In this paper, a mathematical formulation developed planni...

Modeling of the battery for 42V PowerNet system is presented. For the Battery Management System (BMS) algorithm in a Mild hybrid vehicle, accuracy in the battery model is crucial. The battery model is needed for the BMS algorithm as well as for the system computer simulation for the energy management. The battery model was composed of impedance elements and each element of the model is estimate...

Battery Energy Storage System (BESS) is one of the potential solutions to increase energy system flexibility, as BESS well suited solve many challenges in transmission and distribution networks. Examples network’s challenges, which affect network performance, are: (i) Load disconnection or technical constraints violation, may happen during reconfiguration after fault, (ii) Unpredictable power g...

Herein, we propose an advanced energy-storage system: all-graphene-battery. It operates based on fast surface-reactions in both electrodes, thus delivering a remarkably high power density of 6,450 W kg(-1)(total electrode) while also retaining a high energy density of 225 Wh kg(-1)(total electrode), which is comparable to that of conventional lithium ion battery. The performance and operating m...

based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. however, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. to resolve this problem, hybridization of the fuel cell and energy storage device...

Solar energy, despite being inexhaustible, has a major shortcoming; it is intermittent. As a result, there’s a need for it to be stored for later use. The widely used energy storage in photovoltaic system applications is the leadacid battery and the knowledge of its state-of-charge (SOC) is important in effecting efficient control and energy management. However, SOC cannot be measured while the...

Battery lifetime has become one of the top usability concerns of mobile systems. While many endeavors have been devoted to improving battery lifetime, they have fallen short in understanding how users interact with batteries. In response, we have conducted a systematic user study on battery use and recharge behavior, an important aspect of user-battery interaction, on both laptop computers and ...
