Control of Interlinking Converters for DC Multi-Microgrids

In this paper, we consider the control design of interlinking converters in DC multi-microgrids. We present a passivity framework and use this to propose a solution where each ILC satisfies an appropriate passivity condition which leads to stability and scalability of the DC multi-microgrids under reasonable assumptions. We illustrate the practicality of our approach with two examples of various DC-DC converters suitable for interlinking conversion.
