This study investigates a new hybrid energy storage system (HESS), which consists of a battery bank and an ultra-capacitor (UC) bank, and a control strategy for this system. The proposed topology uses a bi-directional DC-DC converter with a lower power rating than those used in the traditional...

Microgrids are a highly efficient means of embedding distributed generation sources in a power system. However, if a fault occurs inside or outside the microgrid, the microgrid should be immediately disconnected from the main grid using a static switch installed at the secondary side of the main...

This paper connects the biofuels literature with genetic modifications literature by considering the potential of genetic modifications for increasing the efficiency of cellulosic biofuels production. This is done for one particular case through analyzing the effect of genetically modified corn...

To effectively manage and save energy and natural resources, the measurement and monitoring of gas/fluid flows play extremely important roles. The objective of this study was to incorporate an efficient power generation and a power management system for a commercial water flow meter thus...

El documento analiza las estrategias de: promoción, producción, desarrollo o adaptación de las energías renovables en el país. El desarrollo de esta investigación partió del actual Plan Energético Nacional en lo referente a los lineamientos en materia de política energética. De igual...

Support through the German Renewable Energy Sources Act (EEG) has led, in the past few years, to an unexpectedly wide expansion of systems for generating solar power (photovoltaics) because the system prices for photovoltaic (PV) systems have fallen at a faster rate than the solar power feed-in...

Feed-in tariffs have proven to be an effective instrument in supporting renewable energies. As a result of the dynamic price trend of photovoltaics, the actual number of systems installed has repeatedly exceeded initial government targets. Therefore, the support for new solar power installations...

This paper presents an acceleration slip regulation (ASR) system for four-wheel drive (4WD) electric vehicles, which are driven by the front and rear axles simultaneously. The ASR control strategy includes three control modes: average distribution of inter-axle torque, optimal distribution of...

The hydrodynamic effects on spectroscopic water detection were microscopically investigated in a gasoline pipe flow. The effects of the gasoline flow rate and the water content on the water droplet characteristics were investigated experimentally using a phase Doppler particle measurement...

When vehicle manufacturers are developing new hybrid and electric vehicles, modeling and simulation are frequently used to predict the performance of the new vehicles from an early stage in the product lifecycle. Typically, models are used to predict the range, performance and energy consumption...
