Enhanced Grid Frequency and DC-Link Voltage Regulation in Hybrid AC/DC Microgrids Through Bidirectional Virtual Inertia Support

IEEE transactions on industrial electronics (1982. Print), 2023
AC mains frequency and dc-link voltage are two of the most important parameters that determine the stability of hybrid ac/dc microgrids. Frequency and voltage deviations beyond the acceptable threshold can lead to unscheduled load curtailments, cascading

In-Band Communications for DC Microgrids

2020 IEEE Global Humanitarian Technology Conference (GHTC), 2020
DC microgrids contain DC power sources, storage, and loads. These microgrids use low data-rated communication to manage the DC voltage and current. The student engineering team have simulated and tested an in-band communications mechanism for use on unshielded DC power wires.

Finite-Time Synergetic Controller Design for DC Microgrids With Constant Power Loads

IEEE Transactions on Smart Grid, 2023
The negative impedance characteristic of constant power loads (CPLs) can cause DC bus voltage fluctuations or even DC microgrid instability. In this paper, a nonlinear synergetic control method is used to guarantee the DC bus voltage stability of DC ...
