Behavior of a microgrid during the transition from grid connected to Islanded mode

Abstract

Behavior of a microgrid during the control mode transition from grid connected to islanded operation «as studied. A detailed microgrid simulation model was developed. Microgrid frequency and voltage control was designed based on the most generic schemes identified after a thorough literature survey on practical microgrids. The simulation study results reveal the impact of generator inertia and the control mode transition delay on the frequency and voltage deviations and load shedding.
