Special Issue Information
Dear Colleagues,
With the development of new power systems and the continuous increase in the proportion of new energy installed capacity, the application scale of power electronic equipment as a means to support renewable energy grid connection, transmission and flexible control is constantly expanding, demonstrating sustainability. As the first line of defense to ensure the safe operation of the power system, relay protection equipment is crucial for the safe and stable operation of the power grid. With construction and changes in the form of new power systems, as well as the increasing complexity of source, grid and load characteristics in the system, relay protection in new power systems is facing new challenges, such as (1) the complexity of the fault characteristic mechanism of new power systems; (2) the reliability and sensitivity of protection principle in new power systems being insufficient; (3) existing protection technologies not fully considering the fault control characteristics of new power systems; (4) the lack of depth in research on artificial intelligence and advanced algorithms in new power system relay protection technology; and (5) the need for further improvement of the performance of fault location and fault recovery in new power systems. Therefore, relay protection is the core and key technology that should be broken through in the new power systems. Please define the scope and purpose of the Special Issue and its relationship to other literature on the topic. You can extend or shorten the contents based on the needs.
(1) Analysis of Fault Mechanism in New Power System
(2) New Technologies for Protection of New Power System Equipment
(3) New Principles of AC/DC Protection for New Power Systems
(4) New Collaborative Technology for New Power System Control and Protection
(5) New Technologies for Fault Control in New Power Systems
(6) New Technologies for Fault Recovery and Fault Localization in New Power 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.
