A Decision Support System for the Stable Real-time Power Management of Onboard Zonal DC Microgrids

Nowadays, the power electronics-based DC distribution is the enabling technology for high-performance marine applications. Resilience and adaptability are the most crucial advantages to foster such controlled systems. Conversely, destabilizing interactions between filtering stages and controlled converters can slow down the onboard implementation. The work presents a Decision Support System (DSS) to identify the optimized solution in reconfiguring the control bandwidths. The latter are to be tuned in real-time by the Power Management System (PMS) to constantly ensure a sufficient stability margin in a zonal DC microgrid. In the proposed C-HIL tests, an HMI will be designed to assist DSS and human intelligence in imposing the proper modulation on converters dynamics. Final real-time trials on DC loads configuration will demonstrate the DSS capability in preventing unstable evolutions, thus ship blackouts.
