DC Hierarchical Control System for Microgrid Applications
In order to enhance the DC side performance of AC-DC hybrid microgrid, a DC hierarchical control system is proposed in this paper. To meet the requirement of DC load sharing between the parallel power interfaces, droop method is adopted. Meanwhile, DC voltage secondary control is employed to restore the deviation in the DC bus voltage. The …
What is a microgrid? | Microgrid Knowledge
A microgrid is a self-sufficient energy system that serves a discrete geographic footprint, such as a college campus, hospital complex, business center or neighborhood. Within microgrids are one or more kinds of distributed energy (solar panels, wind turbines, combined heat and power, generators) that produce its power.
