Distributed power management for DC distribution system with model uncertainties

This paper presents an application of combined model reference adaptive control to a notional DC microgrid system for power sharing and bus voltage regulation. The algorithm is presented in detail and a brief stability analysis is provided. Then, the control algorithm is implemented on a two-converter system feeding a single load through a bus to demonstrate the current sharing accuracy and bus voltage stability provided by the method. MATLAB/Simulink is used to validate the effectiveness of the developed control algorithm through case studies representing typical operating scenarios.
