Energy source

A crucial trend for the future is the integration of wind power (WP) into the grid, in order to guarantee that the source of energy used to replace fossil fuels pollutes the environment. The generation source, the load, or the shortcircuit occurrence will have an impact on the grid, therefore, have a suitable solution to ensure its safe operation.

This paper investigates the system performance of hybrid time-power switching based relaying (TPSR) energy harvesting enabled in the multisource half-duplex relaying network over the Rayleigh fading channel. The outage probability (OP) of the proposed system model with implementing maximal ratio combining (MRC) and selection combination (SC) technique at the receiver is presented and analyzed.

In this article, we explore the operation of the LEACH (Low Energy Adaptive Clustering Hierarchy) protocol - a protocol compatible with low-energy sources and propose a solution to improve efficiency in wireless sensor networks. The simulation results show that our solution is better in terms of the number of packets reaching the base station and the average lifetime of the sensor nodes.

The main contribution of this paper is to show a new AC/DC converter based on the rearrangement of the flyback converter. The proposed circuit only manages part of the energy and the rest is delivered directly from the source to the load. Therefore, with the new topology, the efficiency is increased, and the stress of the components is reduced. The rearrangement consist of the secondary of the flyback is placed in parallel with the load, and this arrangement is connected in series with the primary side and the rectified voltage source.

Several studies have been carried out by optimising only the cost. They have not considered some other risk factors such as political and economic factors in their modelling. Currently, there is no generalised model available to determine the optimal sourcing locations incorporating important factors including risks in international LNG trading. In this study, 12 risk factors were taken into consideration to evaluate the risk.

Geothermal energy constitutes an important renewable resource in Turkey that has been extensively utilized for heating buildings, power generation, greenhouse farming and various other industries. One of the most remarkable geothermal locations in Turkey is the low-enthalpy area of Afyon, where five main low-temperature (30–110℃) geothermal fields are exploited. However, further exploration drilling sites have proven inconclusive, casting doubts on the effective presence of high-temperature geothermal systems in the region.

Although the western Anatolian region is a foci for hydrothermal systems, this region has several high heat-generating granitic intrusive bodies that qualify to be candidates for enhanced geothermal systems (EGS). Considering the future energy requirement, carbon dioxide emissions reduction strategies, food, and water security issues, these granites appear to be the future clean energy source for the country. One such granite intrusive is located in the Kestanbol area in the western Anatolian region.

Polyhydroxyalkanoate (PHA) is stored as an important carbon and energy source in bacterial cells. For biomedical applications, gram-positive bacteria can be better sources of PHAs, since they lack outer membrane lipopolysaccharide. Although gram-positive Streptomyces coelicolor A3(2) has been indicated as a high potential PHA producer, phaC gene that encodes the key enzyme PHA synthase in the metabolic pathway is not determined in its genome.

The study centers around one of the principal challenges of the Polish economy - the development of prosumer renewable energy sources. Poland has the biggest portion of coal inconclusive energy utilization. The development of renewable energy sources is the main test even with environmental protection challenges and EU pressure. Right now, Poland data are taken from World Development Indicators (WDI) of Prosumer renewable energy, nonrenewable energy, economic growth and analyze the effect of prosumer renewable energy under the EKC hypothesis.
