The micro-turbines can be used to supply both thermal and electrical energy demands of islanded microgrid. Depleting fossil fuels and ever-increasing environmental concerns have attracted much attention to the renewable energy resources. Meanwhile, the stochastic nature, non-compliance with the load, inability to meet the thermal load and high cost of the wind and solar resources are disadvanta...
Depleting fossil fuels and ever-increasing environmental have attracted much attention to the renewable energy resources. The Micro-Grid (MG) concept is an appropriate means for increasing the adaptation of these resources with current power system architecture. In this paper a new method is used to solve the problem of unit sizing in a grid-connected MG providing electrical and thermal loads ...
What one experiences today as atmosphere is a transient snapshot and result of its evolutionary history. Much of the development and present status was explained based both on scientific knowledge, and combined with established facts, even speculation. The planet Earth was formed around 4600 million years ago by the gravitational accretion of relatively small rocks and dust, within the solar ne...
The characterization of air pollution)in a particular area is connected with the acquisition of a series of statistically significant data. The actual case referred to is a sampling campaign developed in a station in an urban area (Rome), throughout a period of 12 months. For controlling the behaviour of aerosol pollution according to a most complete characterization the three following apparat...
recently, the use of renewable energies has increased to environmental pollution, limitation of fossil energy resources and energy security one of the means that enable us to use such energies is fuel cells (fc). however, there are many problems in the commercialization of fc from an economically and operation perspective. one of the most important problems is heat management. new heat pipes...
the research used the satellite image (landsat 7 etm ) within the thermal infrared sixth band (tir6) and geographic information system (gis) to determine the air pollution and its relationship with the land cover (lc) and land use (lu) of baghdad city. concentration of total suspended particles (tsp), lead (pb), carbon oxides (co, co2), and sulphur dioxide (so2) were obtained from 22 ground mea...
