Dear Colleagues,

Grid-connected power electronic systems are an integral part of modern power system architectures. The last few decades have seen an exponential growth in grid-connected custom power devices, e.g., renewable energy interfaced inverters, active rectifiers, dynamic voltage restorers, active power filters, motor drives and uninterrupted power supply, to name a few. However, in today’s renewable heavy power grid, the operation of grid-connected inverters has become very challenging due to adverse grid conditions. In order to meet the demand of an ever-changing scenario of the customer devices landscape, innovative techniques are required that can cope with the presence of various distortions in the grid. This will enable a smooth transition towards a more renewable power grid.

This Special Issue will consider recent developments in the modelling, estimation and control of grid-connected converter systems under adverse grid conditions. Both original research articles and reviews are welcome. Topics of interest for this Special Issue include but are not limited to,

• Grid-synchronisation techniques (PLL, FLL etc.);
• Harmonics and grid abnormalities detection techniques;
• Advanced control of grid-connected devices;
• Advanced power converter topology development for distorted grid;
• Topology development, modelling, estimation and control of EV chargers;
• Multifunctional grid-connected renewable energy systems;
• Adaptive and learning-based techniques (e.g., neural networks) for grid-connected systems;
• Energy management of grid-connected systems;
• Control of grid-connected high voltage DC (HVDC) converters and modular multilevel converters (MMC);

Stability and interaction issues in grid-connected converters.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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.
