Influence of power control strategies on the voltage profile in an islanded microgrid

摘要

The emergence of large amounts of distributed energy resources (DER) poses new challenges for the active participation of those units in the control of the grid. In this context, a recent development is the microgrid, which presents a coordinated approach for integrating the DER in the electrical grid. Microgrids are able to operate either connected to the distribution grid or in islanded mode. In this paper, the influence of different power control strategies of DER is studied with respect to the voltage profile in an islanded microgrid. A description of the control strategies is presented, as well as some simulation results for a basic microgrid.
