Heterogeneous small-cell networks (HetSNets) are considered as a standard part of the future mobile networks in which multiple low-power, low-cost user deployed base stations complement the existing macrocell infrastructure. This paper proposes an energy efficient deployment of the small-cells where the small-cell base stations are arranged around the edge of the reference macrocell and the dep...

In this paper, the optimal design of a hybrid energy system (HES), consisting photovoltaic technology integrated with fuel cells (HPV/FC) and relying on hydrogen storage, is performed to meet annual demand residential complex find minimum total net present cost (TNPC), while observing reliability constraint as energy-not-supplied probability (ENSP) considering real meteorological data Kuala Lum...

Social acceptance of fusion reactors depends largely on their economic viability. To investigate this issue, we estimate and compare the cost of electricity (COE) among D-T, D-3He, and D-D fusion reactors. Three types of confinement systems are evaluated: the tokamak reactor (TR), the spherical tokamak reactor (STR), and helical reactor (HR). For each reactor type, COE parameter surveys are per...

Penelitian ini menjelaskan bagaimana menggunakan simulasi perangkat lunak Homer untuk menganalisa ekonomi PLTS ON GRID skala rumah tangga yang terhubung ke jaringan PLN. Nilai dicari dalam metode adalah harga dari Net Present Cost (NPC), of Energy (COE), Break Event Point pada 900 VA. Membandingkan nilai perhitungan faktor konsumsi energi sistem dengan biaya pemasangan PLN PV agar tercapai efis...

Based on results of field testing conducted by the U.S. Department of Energy's National Energy Technology Laboratory (DOE/NETL), this article provides preliminary costs for mercury control via conventional activated carbon injection (ACI), brominated ACI, and conventional ACI coupled with the application of a sorbent enhancement additive (SEA) to coal prior to combustion. The economic analyses ...

Promoting the development of green technologies and replacing fossil fuel vehicles with electric ones can abate environmental anxieties issues associated energy supply security. The increasing demand for requires an upgrade expansion available charging infrastructure to accommodate fast public adoption this type transportation. Ethiopia set a pro-electric cars policy made them excise-free even ...

The power system utility has started to think about the green power technology in order to have an eco-friendly environment. The green power technology utilizes renewable energy sources for reduction of GHG emissions. Odisha state (India) is very rich in potential of renewable energy sources especially in solar energy (about 300 solar days), for installation of grid connected photovoltaic syste...
