Control of AC-AC Interlinking Converters for Multi-Grids

open access: yesIEEE Transactions on Smart Grid
This paper considers the control of AC-AC interlinking converters (ILCs) in a multi-grid network. We overview the control schemes in the literature and propose a passivity framework for the stabilization of multi-grid networks, considering both AC grid-following and AC grid-forming behavior for the ILC connections.

Bidirectional Droop Control of AC/ DC Hybrid Microgrid Interlinking Converter

open access: yes2019 2nd International Conference on Safety Produce Informatization (IICSPI), 2019
In AC/DC hybrid microgrid, interlinking converters is considerable in maintaining power system stability. A bidirectional droop control is designed for interlinking converters. The power of interlinking converters transmission power is decided by AC frequency and DC voltage respectively.
