With the increasing penetration of renewable energy, automatic generation control (AGC) capacity requirements will increase dramatically, becoming a challenging task that must be addressed. The rapid growth of electric vehicles (EVs) provides new approaches for the stable operation of power...

Grid-scale energy storage is one option to reduce curtailment and increase deliverability of transmission-constrained wind. This study examines four hypothetical wind and transmission projects in the United States to quantify the reduction in curtailment under various energy storage...

We present the results of an analysis of the performance of a photovoltaic array that complement the power output of a wind turbine generator in a stand-alone renewable energy system based on hydrogen production for long-term energy storage. The procedure for estimating hourly solar radiation,...

A solar kiln with energy storage can be used for continuous drying. This kiln consisted of several units which were modeled to simulate it in operation. A model was proposed for each unit, and another based on laboratory tests for drying a wooden board by passing air across. These models were...

The hybrid wind–hydro power generation appears to be an attractive solution for isolated, autonomous electric grids in order to increase the wind energy penetration and cost-effectiveness. This work presents a numerical methodology for optimum sizing of the various components of a reversible...

A thermodynamic analysis is presented for an energy storage system without combustion and including thermal recuperation (adiabatic compressed air energy strong (CAES)). The storage volume is optimized and a system layout with thermal storage (TES) and variable configuration is designed. The...

This study focuses on heat transfer enhancement in double pipe energy storage system. Enhancement is achieved by use of metal screens/spheres placed inside the phase change material (PCM), which is paraffin wax and results in increasing the effective thermal conductivity of the combined media of...

Two different options for the autonomous power supply of rural or/and remote buildings are examined in this study. The first one involves a PV – diesel based power system, while the second one integrates RES and hydrogen technologies for the development of a self – sustained power system....

The paper assesses the energy and environmental performance of two solutions designed to complement renewable energy (RE) technologies, in stand-alone power system (SAPS) configuration typical of minor Mediterranean islands, by converting the available RE surplus. The studied SAPS, based on the...

A large number of various sized islands are spread throughout the south-east Mediterranean Sea. Most of these small islands face serious infrastructure problems, like the insufficient power supply and the low quality of electricity available at very high production cost. In an attempt to improve...
