Abstract: A microgrid comprises of multiple distributed generators (DGs) and typically operates in parallel with this main grid. In certain cases this operation might fail and a microgrid may operate in an islanded mode. Synchronization occurs when such an islanded microgrid changes its operational mode back to grid connected operation by reconnection to the grid. Synchronizer used for synchronization of a single machine but a large microgrid which operates with multiple DGs and loads traditional synchronizer cannot be used to control it. This problem needs to be handled properly as it requires DGs to be controlled in a co-ordinated way to achieve synchronization. This paper presents work done on an active synchronizing control scheme which follows the network-based coordinated control of multiple DGs. Simulation results using Matlab/Simulink prove that the scheme is efficient enough to provide reliability in the reconnection of the microgrid.
