Model OverviewComponents in Microgrid Resynchronization to Main GridSimulation ResultsSystem PerformanceA substation connects the microgrid to the main grid. The loads and the PV are connected to the outgoing feeder. The model also contains a separate Operator Control Room subsystem. In a real system, the operator control room can be at the substation or somewhere distant to the microgrid.See more on mathworks icdcm2026
