Impacts de l’insertion des énergies renouvelables sur le réseau de transport HTB.

Abstract

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.
