What is it about?
The paper presents a strong methodology on how to model and design model-based power-controllers for VSC-based power generator when connected to an isolated AC microgrid, in addition to a new switching mechanism for implementing a synthetic inertia provision to support the frequency / speed of the main rotating generator.

Why is it important?
It models the effect of weak grid-connection of the VSCs, and proposes inverse-model controllers to enhance power-control performance, in addition to the development of a new synthetic-inertia switching-mechanism that compares favourably with other methods reported in the literature.
Perspectives
This publication will help better understanding of the accurate model of interfacing VSCs to AC/DC grids, and how using such model, high-performance power-controllers (based on the inverse-model) can be designed for best performance. This also supports a synthetic-inertia provision using a new switching-mechanism which can be implemented within the main controllers of various VSC-based distributed power/energy systems.
