Enhanced Stability in Hybrid AC/DC Microgrids with Controlled Magnetic Energy Router

The incorporation of renewable energy sources is promising for a more sustainable energy future, but it poses issues for microgrid stability owing to the intermittence nature of employed renewable sources. This paper introduces a Magnetic Energy Router (MER)-based hybrid AC/DC microgrid to offer a solution for enhancing stability and control during various operating conditions. Unlike traditional parallel configurations, MER employs a multi-port router to strategically decouple and segment the microgrid, resulting in improved control and resilience. The paper focuses on the design of a reliable Proportional-Integral (PI) controller for a 4port multi-active bridge (MAB) converter. The simulation results demonstrate its performance under different loading conditions. The controller is shown to regulate bus voltage with a faster response time and reduced peak values, ensuring steady operation.
