This paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. In fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. Thepower output of each hydro unit varies with the rate of water discha...

the purpose of this study is to investigate and explore the causes of identity crisis as one of the debilitating consequences of colonial project after the withdrawal of colonial power. in order to do justice to the full-length severity of displacement that was the fruit of indentureship, v. s. naipauls west indian epic, a house for mr biswas, has been scrutinized with the main focus being the ...

Electricity generation in thermal power plants as the largest producer of electricity in Iran is associated with greenhouse gas emissions. In this paper, using the Malmquist-Luenberger method, green productivity, and efficiency changes are measured for 31 thermal power plants (including 12 steam power plants, 13 gas power plants, and six combined cycle power plants) during 2009-2016. The result...

abstract the goal of this research is simulating an optimum reactor to eliminate greenhouse gases, mainly co2, through combined cycle in stacks of power plant, using a strong base (sodium hydroxide) thinned by water. during this process sodium bicarbonate salt is generated together with water and the produced salty water is desalinated and its useful salts are also extracted. four scenarios hav...

Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. The eligibility of a combined heat and power (CHP) system has been investigated as a new power generation methode, in this study. Natural gas fueled SOFC power systems via methane steam reforming (MSR) yield electrical conversion efficiencies exceeding 50% and...
