The effect of DG using fuel cell under deregulated electricity energy markets

The electricity supply industry is undergoing deregulation around the world. A free market approach to buying and selling electricity is forecasted to drop the cost and introduce choice into what has been a monopoly industry. Deregulation has accelerated the development of smaller generators and fuel cells will gradually become more attractive to mainstream electricity users as they improve in capability and decrease in cost. Some of the operating conflicts and the effect of distributed generation (DG) on power quality are addressed. Molten carbonate fuel cell (MCFC) stack dynamic model was developed to analyze a spectrum of dynamic responses from slow to fast transients and a simplified process flow diagram (PFD) of the Santa Clara Demonstration Project is presented. The integration of direct carbonate fuel cell (internally reformed carbonate fuel cell) with a gas turbine is an emerging technology. Fuel cell-microturbine hybrid power plant can be interfaced with the utility grid via a three-phase inverter, controlling active and reactive power
