Abstract

The concept of deregulated energy infrastructure is rapidly shaping the future of power generation and grid constitution. Control, communication and integration of various alternative energy resources within a Distributed Generation (DG) network have opened up areas of new challenges and opportunities. The power interface between a fuel cell system and the distribution grid is one such intriguing issue. With the advent of various grid-interactivity, safety, efficiency and power quality standards (such as, IEEE 1547), the design of a cost effective-high performance power electronic inverter for a fuel cell system is a challenge. In this paper, various design criteria, topologies and control aspects of a grid-tied fuel cell inverter are discussed. An overview of some fundamental design standards, and a systematic approach for topology selection is given. An outline of a possible DSP based hardware configuration, communication and control is also provided. Initial simulation of the proposed scheme along with considerations for practical implementations of fuel cell inverter are discussed.
