Synchronization of Microgrid by Actively Controlling Parameter

Abstract

A microgrid consist of number of distributed generators (DGs) and renewable energy sources, Which operates in parallel with the main grid or in islanded mode. When it come for the parallel operation with main grid, microgrid cannot be Synchronized with main grid by using traditional synchronizer. As microgid operates with multiple DG’s and load, which is continuously varying. So I is necessary o use co-ordinate way to control multiple generators. This paper proposes an active synchronization technique with network based co-ordination to conrol the multiple DG’s. From the simulation results using Simulink dynamic models, it is shown that the scheme provides the microgrid with a deterministic and reliable reconnection to the grid.[38]
