Applying of power electronic converters in grid-connected control of solar cell and fuel cell sources

Abstract

The research on using and exploiting effectively solar cell and fuel cell sources to generate electricity is significant in reducing the climate changes as well as the dependence of power demand on fossil energy sources which are at risk both in running up and causing environmental pollution. Using power electronic converters for grid-connecting of solar cell and fuel cell sources have some advantages such as active fuel input and capability of power transferring in both directions. The combination of harmonic filter circuits to suppress high order harmonics on the grid will also have significant effect on power quality improvement. The article presents simulation results of the grid-connected control model of an integrated solar cell and fuel cell power system using power electronic converters, which maintains maximum capacity of the systems regardless of the connected power loads.

Key words: power electronic converter; grid-connected control; renewable energy; small power sources; distributed sources
