Security Defense Technologies for the New-Type Power System

Dear Colleagues,

With the continuous advancement of energy structure transformation, the new-type power system is presenting the "double-high" characteristics of "high proportion of new energy and high proportion of power electronic equipment". And a pattern has gradually taken shape in which large-scale new energy bases are developed in a concentrated manner and large-capacity AC/DC transmission channels are used for long-distance power transmission. This profound transformation, while enhancing the cleanliness and efficiency of the system, also poses brand-new challenges to the safe and stable operation of the power system. To address the increasingly complex fault characteristics of the new-type power system, the rising difficulty in protection and control, and the escalating risks of extreme disasters, this Special Issue focuses on the construction of security defense technologies for the new-type power system. We have invited experts from the academic and engineering fields to jointly discuss the latest technologies, core problems, and innovative solutions.

Submissions may cover, but are not limited to, the following topics:

1. Fault characteristic analysis under the interactive influence of large-scale renewable energy and power electronic equipment integration.
2. New principles and technology for rapid and selective protection for highly electrified power grids.
3. Fault propagation mechanisms and protection coordination strategies of AC/DC hybrid systems.
4. Fault clearance and recovery technology for UHV AC/DC power transmission systems.
5. Impact of dense integration of nearby renewable energy on the near zone AC protection and adaptive measures.
6. New protection principles and technologies for major equipment such as large generators, transformers, and reactors.
7. Protection and health management for power electronic-based equipment (such as wind power, photovoltaic and energy storage).
8. Equipment condition monitoring, early fault warning, and intelligent diagnosis technologies.
9. System vulnerability analysis under multiple disasters such as extreme weather and cyber-attacks.
10. Evolution mechanisms of cascading failures and rapid blocking methods.
11. System black start, resilient recovery, and adaptive reconfiguration strategies.
12. Wide-area protection, distributed protection, and local coordination control technologies.
13. Application of artificial intelligence and big data in fault diagnosis, protection setting optimization, and decision-making.

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.
