Abstract

This study evaluates the dynamics of DC microgrids (DCMG) with the integration of voltage dependent demand response (VDDR). Previous work evaluates price prediction models for grid operators to estimate local price as a demand side management (DSM) technique. VDDR has been proposed to implement DSM without the need of a dedicated communication link. The dynamic response of a DCMG with VDDR has been evaluated in a situation with limited source power output. This has been done with two different VDDR controller logics: dynamic and fixed hysteresis control. Furthermore, the effect of current rate of change control is presented. The results provide further understanding on the dynamic behaviour of DCMGs, which can be used to create a guideline for the design of source and load control systems.
