My PhD dissertation work focused on the dc microgrid stability and control. We present a robust passivity-based control (PBC) strategy to solve the instability problem of DC-DC power converters with constant power load (CPL) in DC microgrid systems.Based on the PBC, we designed anonlineardisturbance observer (NDO) to improve the control robustnessof the PBC strategy againstsystem disturbances such asload and line variation. Whereas the PBCstrategy is applied toguarantees the system stability due to its property of energy dissipation.We found that, this strategy ensures large signal stability as well as fast recovery performance of the system during disturbance as compared to other nonlinear control strategies.To validate the MATLABsimulation results, we performed the Hardware-in-loop (HIL) experiment on an OPAL-RT real time simulator.Further validations are also presented using a real hardware experimentto emphasize the robustness of the proposed controller.Part of this work is published in “IEEE Journal of Emerging and Selected Topics in Power Electronics” andother conferencepapers arepublished in IEEE Xplore Digital Library.
