Large penetration of PV may affect transient stability when fault occurs on a transmission line. Classical model for a synchronous generator, a constant current source model for PV and a constant impedance model for load are applied to the one-machine-to-infinite-bus model. The critical clearing time is calculated by using equal area criterion and Y method simulation. As a result, a case with larger PV penetration has longer CCT than the case without PV penetration and this result does not depend on the reduction of synchronous generator capacity according to PV output.
