Impact of Wind Energy Integration on Grid Stability, Robustness and
Management
Authors: , ,
Abstract: This work concerns the study of the impact of wind energy integration on the stability and
management of the Tunisian electrical grid. The analysis is conducted using the PSS (Power System
Simulation) in Matlab/Simulink (Model and simulate multidomain physical systems) software to assess the
stability of a power grid that incorporates wind farms, utilizing various indicators of stability and robustness.
The aim is to evaluate the stability of a test transmission grid (IEEE 9 bus) as well as the stability of the
Tunisian grid both with and without a wind power plant, to identify the primary effects of this integration, and
to estimate a maximum allowable penetration rate for the grid. This study is carried out through a series of
dynamic simulations, introducing various disturbances into a model of the national grid. The results indicate
that the integration rate of wind energy should not exceed 20% to maintain electrical parameters within
acceptable limits and to avoid compromising the operational performance of the Tunisian grid.
