Increasing the penetration of variable wind generation in power systems has created some new challenges in the power system operation. In such a situation, the inclusion of flexible resources which have the potential of facilitating wind power integration is necessary. Demand response (DR) programs and emerging utility-scale energy storages (ESs) are known as two powerful flexible tools that ca...

renewable energy sources (res), especially wind power plants, have high priority of promotion in the energy policies worldwide. an increasing share of res and distributed generation (dg), should, as has been assumed, provide improvement in reliability of electricity delivery to the customers. paper presented here concentrates on electricity storage systems technologies and applications pinpoint...

Now, more than ever before, the use of renewable energy is critical to the well being of our planet. Solar energy, in particular, is one of the main sources of renewable energy and the subject of research worldwide. While most renewable energy projects using solar energy target large-scale applications, renewable energy technologies are also suited for small-scale applications. This is evident ...

In this paper, using energy method, small scale effects on the buckling analysis of a double-walled carbon nanotube (DWCNT) under external radial pressure is studied. The constitutive equations derived for a DWCNT using the nonlocal theory of elasticity which Eringen are presented for the first time. By minimizing the second variation of the total energy for a DWCNT, hence, the value of the non...

A mathematical connection is established between the ocean near-surface geostrophic kinetic energy and the small-scale variance of its surface height. The latter is defined as the spatial variance of sea surface height inside a given grid box and represents a basic statistical characteristic of the field, necessary for estimating its vulnerability to sampling error. The former is also computed ...

Magnetic fluctuations in the solar wind are distributed according to Kolmogorov’s power law f below the ion cyclotron frequency fci. Above this frequency, the observed steeper power law is usually interpreted in two different ways: a dissipative range of the solar wind turbulence or another turbulent cascade, the nature of which is still an open question. Using the Cluster magnetic data we show...

This study reports on the findings from the investigation into small-scale (6.25 mL) MFCs, connected together as a network of multiple units. The MFCs contained unmodified (no catalyst) carbon fibre electrodes and for initial and later experiments, a standard ion-exchange membrane for the proton transfer from the anode to the cathode. The anode microbial culture was of the type commonly found i...

I consider the next-to-leading high-energy cluster expansion of large-k double jet production in QCD, and I determine the corresponding one-loop quark and gluon impact factors for a self-consistent energy scale. The result shows that coherent angular ordering of emitted gluons holds for hard emission also, and singles out a scale which in essentially the largest virtuality in the process. Both ...

Jordan‟s energy balance is largely dominated by combustible fuels. However, the country is well endowed with solar, wind and oil shale resources, in addition to large and small-scale hydropower projects. Based on available data and the current analysis, it is believed that there are at least 6-10 candidate sites in the western part of Jordan and 2-3 locations in the eastern plateau, which could...
