Improving the Performance of a Line Regulating Converter in a Converter-Dominated DC Microgrid System
Abstract
This paper describes the controller design procedure for a line-regulating converter in a converter-dominated dc microgrid system. The purpose of the controller is to mitigate the effects of the constant power loads on the stability and performance of the dc microgrid system. In this work, first, the overall structure, operation, and building blocks of the dc microgrid under analysis are introduced. Next, the dynamic model of the dc microgrid and the required transfer functions for the controller design are derived. Then, two proposed controller design methods are introduced and implemented on an virtual line-regulating converter in a dc microgrid system. Finally, the controller design methods are verified experimentally using the results from a built prototype dc microgrid system.
