Analysis of the Repowering Wind Farm of Sidi-Daoud in Tunisia

Since 1980s, several countries have been committed in the exploitation of wind energy sources. The lifetime of these energy sources is generally estimated between 15 and 20 years. Therefore, these wind turbines must be dismantled and replaced by others that are more powerful and more performing. In this context, the Tunisian Electricity and Gas Company has launched, since 2015, a study of the re-equipment (repowering) of the Sidi-Daoud power plant in the north-east country. This paper deals with the repowering study of the Tunisian wind farm. To verify the impact of new wind turbines on the power grid, we performed simulations for the following two faults: a short circuit at the wind farm connection bus and a loss of a conventional power plant of the Tunisian grid. These simulations are performed using commercial PSSE software containing different generic models of wind turbines. Finally, the robustness test is performed and gives good results.
