Distributed Secondary Control for DC Microgrids Leveraging a Fully Actuated System Approach

This paper explores the application of a Fully Actuated System (FAS) approach in the secondary control strategy for DC microgrids. Through an in-depth analysis of the microgrid electrical and control architecture, we propose a large-signal model that integrates circuitry and control, with a specific focus on addressing coupling issues among distributed generation units (DGs). Based on this foundation, a distributed FAS-based secondary control strategy is designed, utilizing the FAS theory to tackle coupling and control challenges in DC microgrids. Simulation results demonstrate the effectiveness of our proposed secondary control method in maintaining system stability and economic efficiency.
