1 Real-Time Digital Simulation of Microgrid Control Strategies

This paper evaluates microgrid control strategies prior to actual implementation using a real-time digital simulator. The microgrid model includes photovoltaic generation, a battery, an emergency generator, loads and a vehicle-to-grid enabled electric vehicle charging station. Three operational scenarios are studied: grid-connected operation; seamless transition to islanded mode with the battery inverter operating in grid-forming mode; and islanded operation using the emergency generator when the battery is discharged.
