DC microgrids are composed of multiple sources and loads that are interconnected through power electronic converters. They are integral and constitute power systems found in various applications such as ships, aircraft, and others. The loads which are driven by power electronic converters act as constant power loads (CPLs) on the DC bus. The negative incremental impedance of CPL results in the instability of the grid. The paper introduces a flexible DC energy router (FeDER) which is a modular and scalable power management unit built utilizing wide-band-gap (WBG) semiconductors. FeDER-based modeling of DC microgrids is presented in the paper. The Smart Resistor control of the FeDER modifies the CPL into an adjustable positive resistor ensuring stability. Enhanced region of attraction (ROA) is estimated for the DC microgrids when Smart Resistor control of the FeDER is enabled. Further, the simulation results demonstrate the effectiveness of the proposed control strategy.
