Interface of a fuel cell distributed generator with distribution system network

Renewable energy sources has become more commonplace source to produce electricity, fuel, and heat, reflecting the major threats of air pollution, exhaustion of fossil fuels, and the environmental, social and political risks of fossil fuels and nuclear energy. Fuel cells will start out as a high-cost technology, supplying electricity and gradually become more attractive to mainstream electricity users as they improve in capability and decrease in cost. New technologies including inverter with real and reactive power control are becoming available to provide a uniform standard interconnection of distributed resources with electric power system. Some of operating conflicts and the effect of distributed generation on power quality are addressed and possible solutions are suggested. Simulation results of a fuel cell power plant model have proved load tracking capability following the real and reactive power change of the load.
