The increasing penetration of generation power plants\udbased on renewable energies in the electrical networks has\udboosted the number of systems connected to the grid. In this\udscenario the microgrid, providing advanced functionalities to\udimprove the stability and operation of the network, have become\udvery popular. In this paper a control strategy for the microgrid\udmanagement is presented. The proposed system improves the\udperformance of microgrids and its interaction with the main\udnetwork, or another microgrid, under grid voltage transients.\udThis technique gives rise to a simple and robust control scheme\udto ensure the appropriate microgrid disconnection, and further\udresynchronization and reconnection, from the main grid. In the\udfollowing, the control algorithm for the intelligent connection\udagent will be shown, and the grid synchronization system, as\udwell as the voltage and current control loops will be detailed.\udFinally, results obtained using the MATLAB/Simulink & PSIM\udplatform will be presented and discussed.
