PCC voltage analysis of a hybrid generating system in case of utility side fault

This paper deals with the PCC voltage analysis of a hybrid generating system consisted with STS, PCS, and load. In case of utility side fault fast and proper control of the PCS output power is necessary to provide undistorted voltage at PCC. The suggested control method guarantees the voltage at PCC can be maintained to the normal value within 1/8 cycles regardless of the fault class. The usefulness of the proposed control method is verified through simulation results.
