Coordinated control and operation of a multi-microgrid system

The concept of a microgrid is evolving due to the rapid growth of renewable energy resources and advancement in power electronics technology. The multi-microgrid operation is a way of improving the reliability of the overall system especially when the utility is absent. In this paper, a multi-microgrid system consisting of two microgrid structures with DFIG-based wind energy and solar energy based generation along with battery energy storage system is proposed. A coordinated control and operation of the multi-microgrid system are achieved in the grid-connected and isolated mode under various operating conditions.
