“…If the isolation or a high ratio of the voltage conversion is required, a transformer is usually integrated into the system. The main drawback for this configuration is that the low-frequency transformer placed at the output of the inverter makes the system very bulky and expensive (Palsson et al, 2000;Costamagna et al, 2001;Bayoumi et al, 2001Bayoumi et al, , 2002Selimovic and Palsson, 2002;Alcaide et al, 2006;Pillai et al, 2008;Maamoun et al, 2002). 2 It produces sufficient voltage for the inverter input so that the required magnitude of the AC voltage can be produced .…”

“…Therefore, the output voltage should be regulated at a desired value. To keep the polarisation characteristic at a constant level, additional parameters such as cell temperature, air pressure, oxygen partial pressure, and membrane humidity also need to be controlled (Selimovic and Palsson, 2002).…”

“…The control of a utility connected inverter, as shown in Figure 9, is developed with constant power control (Selimovic and Palsson, 2002). The controller works similarly as described in the photovoltaics section of this report.…”

Distributed generation (DG) in smart grid (SG) is being employed as a means of achieving increased reliability for electrical power systems as regarded by consumers. As the most of DG technologies utilise renewable sources, the power electronic interface plays a vital role to match the characteristics of a DG unit with the grid requirements. This paper presents the power electronics capabilities required for DG systems in SG to convert the generated power into useful power that can be directly interconnected with the utility grid and/or that can be used for consumer applications. Because of the enhancement and the different power ranges of power electronics devices, the development of advanced power electronic interface that is scalable to meet different power requirements, with modular design, lower cost, and improved reliability, will improve the overall performance and durability of smart grid distributed power systems.

“…recuperator, steam boiler, and heat exchanger network). Selimovic et al, 2002 proposed that networked SOFC stacks incorporated with gas turbine be used to further produce electricity from an exhaust gas combustion stream. It is known that a gas turbine is classified as a low efficiency mechanical power device as well as an entropy lost afterburner.…”

“…In another approach, Burer et al [4] presents a SOFC/gas-turbine hybrid as one subset of a larger power, heating, and cooling cogeneration system model. Palsson, et al [5] developed a two-dimensional planar SOFC model to add further fidelity and flexibility to the system and proceeded to evaluate several novel concepts, including networked SOFC stacks [6]. Even ground-based mobile applications using hybrid SOFC/gas turbines have been examined, presented by Winkler and Lorenz [7].…”

Recent interest in fuel cell-gas turbine hybrid applications for the aerospace industry has led to the need for accurate computer simulation models to aid in system design and performance evaluation. To meet his requirement, solid oxide fuel cell (SOFC) and fuel processor models have been developed and incorporated into the Numerical Propulsion Systems Simulation (NPSS) software package. The SOFC and reformer models solve systems of equations governing steady-state performance using common theoretical and semi-empirical terms. An example hybrid configuration is presented that demonstrates the new capability as well as the interaction with pre-existing gas turbine and heat exchanger models. Finally, a comparison of calculated SOFC performance with experimental data is presented to demonstrate model validity.
