“…The most significant advantages of fuel cells are low emission of greenhouse gases and high power density. The energy density of a typical fuel cell is 200 Wh/l, which is nearly ten times that of a battery (Xu et al, 2004;Kirubakaran et al, 2011). The efficiency of a fuel cell is also high, in the range of 40% to 60%.…”

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.

“…Fuel cells can be classified into five different categories based on the electrolyte chemistry: proton exchange membrane fuel cell (PEMFC); solid oxide fuel cell; molten carbonate fuel cell; phosphoric acid fuel cell; and aqueous alkaline fuel cell. In these kinds of fuel cells, PEMFCs are being rapidly developed as the primary power source in movable power supplies and distributed generation (DG), because of their high energy density, low working temperature, and firm and simple structure (Xu et al 2004). Table 2 provides a summary of various fuel cell types and corresponding characteristics (Distributed Utility Associates 2003).…”

“…In some systems, a communication bus may be included to exchange information and manage power flow between the sources. A number of socalled front-end DC-DC converters, such as the interleaved boost converter [1], the current-fed push-pull converter [2], the phase-shifted full-bridge converter [3], the three-phase converter [4] etc., have been developed to interface sources. Many papers also contribute to the design of bidirectional converters to connect storage [5][6][7].…”

Multiport DC-DC converters are of potential interest in applications such as generation systems utilising multiple sustainable energy sources. A family of multiport bidirectional DC-DC converters derived from a general topology is presented. The topology shows a combination of DC-link and magnetic coupling. This structure makes use of both methods to interconnect multiple sources without the penalty of extra conversion or additional switches. The resulting converters have the advantage of being simple in topology and have a minimum number of power devices. The proposed general topology and basic cells show several possibilities to construct a multiport converter for particular applications and provide a solution to integrate diverse sources owing to their flexibility in structure. The system features a minimal number of conversion steps, low cost and compact packaging. In addition, the control and power management of the converter by a single digital processor is possible. The centralised control eliminates complicated communication structures that would be necessary in the conventional structure based on separate conversion stages. A control strategy based on classical control theory is proposed, showing a multiple PIDloop structure. The general topology and a set of three-port embodiments are detailed.
