Power Electronics-Based Energy Management System for DoN Microgrids Postgraduate School [video]

Abstract

An Energy Management System (EMS) is a power electronics-based controller that monitors power flow and matches load power demand to the available electric power. Power can be available from the AC grid, various energy sources (including renewables) and energy storage devices. An EMS can control distributed generation resources so that they become a microgrid with respect to the main AC grid. The EMS allows a microgrid to operate connected to the grid or in islanding mode when power from the main grid is not available. The EMS developed in the past few years at the Naval Postgraduate School has been applied to microgrid scenarios that could be used in Department of the Navy (DoN) installations, expeditionary camps or ships. EMS applications to DoN microgrids are attractive because an EMS makes the critical loads in a microgrid independent from any AC grid malfunctions, thus improving energy security.
