초록

This paper analyzes the undervoltage protection based on the dynamic stability of a PV system at fault conditions. A 3 MW PV system is modeled by Matlab/Simulink. Then, the distribution system interconnected with the PV system is modeled. This paper simulates the various fault types and analyzes the stability of the PV system at fault conditions. It is concluded that the undervoltage protection of the grid-connected PV system in Korea standard needs to be modified based on the results of the stability analysis.
