Special Issue Information
Dear Colleagues,
This Special Issue is focused on advanced protections for power systems with a high penetration of inverter-based resources (IBRs). Short-circuit contributions from IBRs are completely different from the traditional contributions from synchronous generation, and this fact can have an important negative impact on the behavior of the power transmission system protections. Furthermore, the short-circuit contributions from IBRs are dependent on the control strategy of inverters, whose means of performing the simulations are not easily available. On the other hand, power system dynamics is also negatively affected due to the low inertia feature of these systems; consequently, special protection systems and/or improved control strategies can potentially be necessary to avoid possible general black-outs. Thus, the scope of this Special Issue covers the design, analysis, and testing of protections for these systems, as well as the modeling, testing, innovations, and grid-code requirements for grid-following and grid-forming inverters during short-circuits and during major disturbances in the transmission grid. These topics have been analyzed during recent years, and this Special Issue has the explicit purpose of offering an updated perspective on them. Contributions are specially welcomed from manufacturers of protective relays or grid-connected inverters, developers of power system analysis software, experts in the dynamic and transient analysis of electric power systems from electric utilities or from engineering consulting firms, developers of grid-codes, and academic researchers.

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.
