description: The integration of renewable energy has led to introduce the concept of local use of these new production sources. We can define the Microgrid paradigm as an aggregation of several distributed power sources that can supply their local charges. These microgrids may be islanded to ensure the continuity for supplying the loads in both operation modes. To provide the reliability of the network, a strategy to protect the generators and the Microgrid itself has been proposed. In this thesis, the similarities and differences between conventional generators and the generators connected to the network using the power electronics converter are firstly presented. Then, we present the design of a voltage source connected by a power electronic converter and LC filter, based on gas micro-turbine as the controllable primary energy source. We study the possibilities for the generator to remain connected in case of voltage sags (fault-ride-through) while being protected against the overcurrents. We have proposed two different solutions to limit these generator currents. In addition, to ensure continuity of supply the loads in two operation modes, we integrated an islanding detector based on the ROCOF (Rate Of Change Of Frequency) relay in the control system. An experimental validation for this work was realized using PHIL (Power Hardware in the Loop) real-time simulation. Finally, a coordinated protection plan valid in both operation modes and with different types of sources was presented. This strategy was tested on a simulated example of microgrid on real-time simulator
