Researchers and scientists to ease due to electric power generation using fossil fuel plants with environmental pollution is seeking, in the discovery and improve the methods of generation using renewable energies. Floating solar chimney technology of the most promising technologies that can be used in power stations with solar chimney is considered. The research aims to give results on a proposal to determine the specifications for the plant of this kind in the climate of the city of Homs, for example, and the study of the behavior of this station and analyze the most important parameters affecting it. In this research study hydrothermal behavior floating solar chimney in the climate of the city of Homs by a program written in a language programming EES thermal power station.

In this paper, an analysis of the balance of power and Exergy hyphen to
the station by solar radiation using thermal programming language EES, and
solving inter equations of mathematical model is written for the station
floating balances of the chimney in order to facilitate the analysis. We chose
thermal EES programming language to write a program to solve
mathematical equations governing the balance of power in this type of
stations due to its flexibility in dealing with thermodynamic tables, and the
possibility of solving linear equations, and many other features.
This research shows the necessity of building the solar electric generating system to provide a clean renewable energy and to meet people's needs of electrical energy at Peak-Load to keep a clean environment in Palmyra region. This paper concluded a
study of electric generating power plant with 30 MW capacity during day. A part of heat power collected in a solar field is stored in sensible thermal energy storage for covering Electrical Peak Load when the plant operates at night. This research showed the advantage of constructing the solar system with a Parabolic Trough in the solar
field. The amount of heat collected during months of the year is high and the hours operating at daytime were great. The building of solar-electric plant is valid technically and economically. This research performed a design of solar field and its Parameters using Computer Program (Language C++) and calculated the most important plant
performance during months of the year.
Solar radiation which reaches the earth surface in Palmyra city has high rates, so we introduce this research to study the operation of a solar electric power plant with parabolic trough solar collector type. Electric power plants are usually designe
d to operate at nominal design power and flow rate, pressure, specific steam temperature. In this case the obtained efficiency is relatively high, but the real conditions in which the plant operates and supplies the electric grid, in addition to the climate variations during monthes and seasons, all lead to a deviation in power value from nominal value, so the plant operate at partial loads. We used the analytical method in this research to study the variation in power plant parameters as the steam turbine load changes. In other words, the study of main plant parameters variation due to variable partial loads. We calculated steam pressure variations through turbine stages and its effect on changing steam flow rate to the recovery water heaters. In addition, we calculated the amount of heat consumed through turbine unit, turbine unit efficiency, and the total efficiency of the power plant.
Electric energy is very important for sustaining the good life on the planet's surface, especially since civilization has become associated with this type of energy. Solar photovoltaic (PV) is one of the most suitable applications for converting sunl
ight into electrical energy. The appropriate use of solar energy is an important topic for reducing dependence on fossil energy sources that are used to generate electricity, and thus reducing the emissions of greenhouse gases on the planet's surface. Globally, because of environmental conditions, other methods of generating energy being searched for that are less harmful than traditional methods, which rely on a large percentage of them on generating stations that run on fossil fuels. This research discusses electrical power generation using solar energy cells and the effect of these cells on the Syrian electrical grid so that a study of a solar energy farm project provides the data required when working on implementing such a project, and these data are voltage control, load flow, total harmonic distortion coefficient levels. To implement such a project, the model must be designed and we chose the ETAP program for that.
