The fuel cells have numerous applications: houses, industries, hospitals, vehicles etc. Another facet of these fuel cell applications is distributed generation, the implementation of various power generating resources, near the site of need, for reducing reliance on grid power. Fuel cells generate electricity from hydrogen by a chemical process. In this paper a solid oxide fuel cell mathematical model is adopted. The solid oxide fuel cells are very efficient and the technology is most suited to applications in the distributed generation. The main aim of the paper is to achieve the control of the fuel cell for stand-alone and grid connection. To achieve a grid interface and stand-alone working by designing suitable power conditioning units. The power conditioning unit is needed for the processing of the raw power output of the fuel cell in order to make it usable. The power conditioning unit might consist of only a DC/DC converter or the two stages of a DC/DC converter and a DC/AC inverter. For the stand-alone part the concentration is on the controlled DC power thus, only a boost converter (DC/DC) stage is used. For the grid interface of the solid oxide fuel cell controlled AC power is needed at the interface point, thus, both stages; boost converter as well as the inverter (DC/AC) are needed. A power conditioning unit is designed for this solid oxide fuel cell and for fuel cells in general. The fuzzy logic control strategy is used for designing the controllers.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

Several performance-monitoring techniques based on linearization and empirical estimations have been developed. However, there is a need for nonlinear modeling for the power plant performance analysis in order to meet the growing demands of economic and operational requirements. In the present research neural networks are used to model the thermodynamic process of a coal-fired power plant, based on actual plant data and simulated data obtained from mathematical models that provide information that is currently not directly available. A sensitivity analysis study is performed to determine the effect of various plant variables on an essential performance parameter, namely, coal flow rate. The safe operation of a coal-fired power plant also requires correct operation of plant instrumentation. Failed instruments provide inaccurate information on the state of a process, which can lead to undesirable or inefficient operation of the power plant. Artificial neural networks are used to develop the analytical redundancy to infer the state of important plant parameters. A sensitivity analysis study is performed to determine the critical parameters influencing the estimated plant parameters.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

Each network node is immersed in its local information environment. If a node is isolated from the rest of the system, then its perception of - as well as its response to the system's information environment is strictly local and based only upon data provided by its local sensor observations. However, completely autonomous responses to such locally determined perceptions can be undesirable from certain global network level perspectives. Fratricide, multiple engagements by weapons platforms and saturation of sensor resources by soft-kill weapons usage are all examples of unintended consequences of ignoring the global picture. In those cases where the exercise of some degree of coordination between individual platform elements is required for global coordination, it is necessary to have available for use by the system's decision functions sufficiently representative perceptions of pertinent aspects of the system's universal information environment. Such a network of perceptions must necessarily be synthesized using the mixture of measurements gathered from the local information environments of individual platform sensors. A method for quantifying the quality of perceptions has been developed. This method enables one to study several important system level problems from a perception quality perspective.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.
