Abstract
This article provides a comparative study of the technical requirements applied by the two Tunisian and Algerian countries. This comparison including Low Voltage Ride-Through (LVRT) and High Voltage Ride-Through (HVRT) is provided and discussed. As well, each country establishes its own network code to meet the minimum technical criteria required and revises it frequently to cope with new modifications of the public service, to keep the protection, the quality of the power supply, the reliability and the stability. This comparison showed that the two countries have a great similarity in their grid codes almost 90% and almost 100% in certain intervals. All results have been checked and carried out using real electrical parameters data.
