Coordinating Multi-Inverter Microgrids: Synchronization, FRT, and Control Hierarchies

Dear Colleagues,

This Special Issue focuses on advancing the coordination, stability, and resilience of multi-inverter microgrids as they become a central pillar of modern distributed energy systems. With the growing penetration of renewable energy sources, microgrids now rely heavily on networks of parallel inverters that must operate synchronously, robustly, and hierarchically. Ensuring seamless synchronisation among distributed inverters, securing reliable fault ride-through (FRT) capability, and developing effective multi-layer control structures have, therefore, become essential for maintaining power quality, operational safety, and dynamic stability.

This Special Issue welcomes contributions that address fundamental challenges and propose innovative solutions in areas such as distributed and hierarchical control strategies, grid-forming and grid-following inverter behaviour, advanced synchronisation techniques, coordinated protection schemes, resilience enhancement, and real-time optimisation. Studies exploring the interaction between inverter-dominated microgrids and wider power networks, as well as experimental validations, hardware-in-the-loop testing, and high-fidelity simulations, are highly encouraged.

By gathering research from across power electronics, control engineering, and smart-grid technologies, this Special Issue aims to provide a comprehensive overview of emerging methods that support secure and flexible multi-inverter microgrid operation. The overarching goal is to promote solutions that enable stable integration of diverse distributed energy resources and strengthen the reliability of future low-carbon energy systems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
