| Abstract: |
| Since micro-sources are mostly interfaced to microgrid by power inverters, this paper gives an insight of the control
methods of the micro-source inverters by reviewing some recent documents. Firstly, the basic principles of different
inverter control methods are illustrated by analyzing the electrical circuits and control loops. Then, the main
problems and some typical improved schemes of the ωU-droop grid-supporting inverter are presented. In results
and discussion part, the comparison of different kinds of inverters is presented and some notable research points is
discussed. It is concluded that the most promising control method should be the ωU-droop control, and it is
meaningful to study the performance improvement methods under realistic operation conditions in the future work. |
