System Modeling and Optimization

Theoretical modeling has played an important role in HESS performance validation and optimization. Several methods and models exist to connect electrochemical supercapacitors with primary power sources, as discussed earlier in reference to FCs and battery hybrid systems. In consideration of the vast quantity of topologies, including active and passive design strategies, a [Pg.257]

A number of models describing supercapacitor resistor and capacitor behaviors used to mimic their performances in power systems have been reported and include classical equivalent, ladder circuit, and lumped or distributed parameter electrical and Debye polarization cell models [6]. An established design of a dynamic model of the often-used polymer electrolyte membrane fuel cell (PEMFC) is included in MATLAB and Simulink software to simulate performance under varying conditions specific to applications. [Pg.259]

The National Academy of Sciences of Ukraine suggested that an economic-environmental-social model be devised and employed for the purposes of the country s sustainable development. This is a very complex and time-consuming approach that may not be usable at this time of industrial restructuring, privatization and other involved processes occurring in a collapsed national economy. An alternative tactics is put forward, which is applicable at both national and regional level. Instead of mathematical modeling and optimization, it uses systems approach and decision theory techniques. [Pg.28]

Finally, a well-instrumented experimental distillation column that has been interfaced to an industrial distributed control system was used to show the implementation of the techniques described in previous chapters in an actual on-line framework, using industrial hardware. In this case, the usefulness of data reconciliation, prior to process modeling and optimization, was clearly demonstrated. [Pg.268]

Modeling and optimization of chemical sensors can be assisted by creating equivalent electrical circuits in which an ordinary electrical element, such as a resistor, capacitor, diode, and so on, can represent an equivalent nonelectrical physical parameter. The analysis of the electrical circuit then greatly facilitates understanding of the complex behavior of the physical system that it represents. This is a particularly valuable approach in the analysis and interpretation of mass and electrochemical sensors, as shown in subsequent chapters. The basic rules of equivalent circuit analysis are summarized in Appendix D. Table 3.1 shows the equivalency of electrical and thermal parameters that can be used in such equivalent circuit modeling of chemical thermal sensors. [Pg.55]

In 2001, the SRS announced its choice of CSSX as the baseline cesium-removal technology over small-tank precipitation (a small-scale version of the ITP process) and ion exchange with CST for its Salt Waste Processing Facility (SWPF) to go into operation in 2010 [22], An optimized solvent system, model, and flowsheet were developed and demonstrated in 2001 and 2002 [37,49], and a modular concept was developed by ORNL in 2003 [68], Thus, the past decade has seen the emergence and maturation of a powerful new technology based on a macrocyclic cation receptor designed to function in solvent extraction to meet the critical need of the USDOE for a means of cleanly separating Cs from alkaline tank waste. [Pg.385]

In order to model and optimize the behaviour of a continuous system for TiC>2 powder production on a laboratory pilot scale, we need kinetic data forthe involved reaction. The aim of this study is then to get such informations on TTIP decomposition in supercritical isopropanol. [Pg.133]

There are numerous advantages of using continuum models. They are widely used for system design and optimization. Continuum models tell us important information about the system, e g., discharge curves, state-of-health of the battery, cycle life behavior and subsequently capacity fade rate, etc. Battery models are also useful in predicting non-measurable internal variables such as solution phase concentration, solid phase concentration etc. This can be used to observe or measure buildup or loss of a certain chemical species within the domain of the battery and can be used efficient-... [Pg.327]

First maintenance models were built to manage the maintenance operations of a single component. Then, researches focus on the modelling and optimization of maintenance of multi-component systems (Cho Parlar 1991). [Pg.541]
