With the increasing integration of renewable energy sources in the transmission
systems, the effect of a high penetration of these sources on the power system stability becomes a very
important issue. The objective of this research is to study the impact of renewable energy on the
transient stability of the electric transmission system. By monitoring synchronous generator behavior
when a short circuit occurs on transmission lines, in different locations and different types of
disturbance on the power grid. Thus their ability to maintain synchronism when inserting a renewable
energy source at high rates, and following the change in the topology of the electrical network due to
the separation of a transmission line. A control methodology proposed to demonstrate the impact of
PV penetration sources on rotor angle stability, and improve their effect by using STATCOM. The PV
effect on the transient stability of the power system is shown by its effect on the angular position of
the synchronous generator rotor, which in turn is related to its contribution to the total capacity of the
generator, and the faults location on the grid. The simulation results show the efficiency and durability
of the control methodology with PV and STATCOM, to improve the rotor angle stability of the
generators.
