Abstract

This paper focuses on improving reliability in DC microgrids interconnected with power-electronics-interfaced distributed generation (DG) units. We propose a novel primary voltage control approach, based on projection-based operators, referred to as retrofit control, by which one can control DG units to stabilize their voltage in the presence of actuator uncertainties. The proposed control approach only requires the model of DG units for controller design and does not depend on other DG units' models. We derive decentralized conditions for the voltage stability of the closed-loop microgrids that are not dependent on line parameters, power loads, and interconnections among DG units. Theoretical results are backed up by simulation case studies in MATLAB/Simscape Electrical.
