چکیده
Modern AC/DC microgrids have undergone significant changes due to the increase in high-power loads and the development of energy storage systems. This paper presents a nonlinear dynamic modeling and control framework for a combined AC/DC microgrid incorporating a synchronous generator, a six-pulse rectifier, and an energy storage system (ESS). An ESS-based PI-controlled DC/DC converter is designed to regulate the DC-link voltage and mitigate transient disturbances. System stability is analytically assessed using the second Lyapunov method, providing a rigorous nonlinear stability guarantee under multiple disturbance scenarios. Time-domain simulations demonstrate that the proposed control strategy significantly improves transient performance, reducing DC-link voltage sag to below 6%, limiting overshoot to under 8%, and shortening settling time by more than 55% compared to the uncontrolled case. The results confirm the effectiveness of the proposed ESS-based control approach in enhancing the dynamic stability and robustness of hybrid AC/DC microgrids.
