Analytical derivation of PQ indicators compatible with control strategies for DC microgrids

Power quality related to DC microgrids is still on virgin grounds of research. However, it may play an important role both in the design stage and on the DC microgrid control scheme to be adopted. Currently there is no comprehensive, quantitative and qualitative analysis on which of the power quality features are the most stringent constraints to be taken into account. This work is an attempt of defining and quantifying a set of power quality indices for DC microgrids. We relate our analysis on the design aspects of DC/DC power converters that are the most critical elements interfacing sources and loads in a stand-alone low voltage DC microgrid.
