Implementation of Active Type SFCL for Hybrid Renewable Energy Sources Based DG for Reduction of Fault Current and Over Voltage

Abstract

The use of the renewable sources increasingly, application of the distributed generation (DG) in the distribution system acquired more attention. The DG systems are powered by micro sources such as fuel cells, photovoltaic (PV) systems, and wind base systems. PV distributed system in which the solar source is low dc input voltage interfaced to grid using front-end conversion. Wind energy has been recognized as important renewable energy resources because it is clean, abundant and pollution free for the application of distributed generation (DG). In this paper Hybrid system both PV cell and wind energy used as source to the converter. Distributed Generation Resources are increasingly used in distribution systems due to their great advantages. The presence of DG, however, can cause various problems such as miss-coordination, false tripping, blinding and reduction of reach of protective devices.
