Fossil fuel consumption problems and water crisis are serious dangers. Using renewable energy is a solution to reduce fossil fuel consumption. Photovoltaic is a renewable energy generation method which is abundantly used all over the world. By installation of solar panels on the surface of water, the efficiency of panels increases and in addition, the surface evaporation of water will be reduce...

High fossil fuel prices have rekindled interest in nuclear power. This paper identifies specific nuclear characteristics making it unattractive to merchant generators in liberalized electricity markets, and argues that non-fossil fuel technologies have an overlooked ‘option value’ given fuel and carbon price uncertainty. Stochastic optimization estimates the company option value of keeping open...

The study started with the requirement that a photovoltaic (PV) power source should be integrated with other supplementary power sources whether it operates in a stand-alone or grid-connected mode. First, fuel cells for a backup of varying PV power were compared in detail with batteries and were found to have more operational benefits. Next, maximizing performance of a grid-connected PV-fuel ce...

45 ISSN 1758-3004 10.4155/CMT.10.7 © 2010 Future Science Ltd CO2 emissions from fossil fuel combustion are the largest net annual flux of carbon in the earth–atmosphere system and represent the dominant source of greenhouse gas forcing [1]. In order to better understand other components of carbon exchange between the land, oceans and atmosphere, improved quantification of fossil fuel CO2 fluxes...

This document sets forth procedures for establishing maximum emissions levels for all fossil-fuelbased thermal power plants with a capacity of 50 or more megawatts of electricity (MWe) that use coal, fuel oil, or natural gas.1 Conventional steam-producing thermal power plants generate electricity through a series of energy conversion stages: fuel is burned in boilers to convert water to high-pr...

This paper presents a general architecture and a platform developed to implement distributed applications as a set of cooperating intelligent agents. It also shows how this architecture has been used to implement a distributed control system for a complex process: the economic control of a fossil-fuel red power plant. Agents in this application encapsulate diierent distributed hardware/software...

This paper deals with bumpless transfer between a number of observer-based controllers in a gain scheduling architecture. Linear observer-based controllers are designed for a number of linear approximations of a nonlinear system in a set of operating points, and gain scheduling control can subsequently be achieved by interpolating between each controller. The Youla-Jabr-Bongiorno-Kucera (YJBK) ...

Introduction of closed cycle gas turbines with their capability of retaining combustion generated CO2 can offer a valuable contribution to the Kyoto goal and to future power generation. Therefore research and development at Graz University of Technology since the 90's has lead to the Graz Cycle, a zero emission power cycle of highest efficiency. It burns fossil fuels with pure oxygen which enab...

A solar-aided coal-fired power plant realizes the integration of a fossil fuel (coal or gas) and clean energy (solar). In this paper, a conventional 600 MW coal-fired power plant and a 600 MW solar-aided coal-fired power plant have been taken as the study case to understand the merits of solar-aided power generation (SAPG) technology. The plants in the case study have been analyzed by using the...
