Advances and Experiences in Protection Systems in Modern Power Systems

Dear colleagues:

Modern power systems are changing at a rate never seen before in order to cope with the requirements of a future carbon-neutral economy. The changes in the power system are adding new challenges to its secure control and operation. Additionally, the power system and its components are not entirely immune to faults or by attacks; therefore, the reliable and secure operation of the modern power system requires the appropriate proper protection system. The massive penetration of power-electronic converter-based technologies is dramatically changing the dynamics of modern power systems. Modern power systems are experiencing a reduction in the short circuit levels at a time that transients are becoming faster and faster and less damped, all of which makes the reliable operation of protection systems more challenging. The most recent development in power system protection schemes takes advantage of the technological developments of the digitalization of the power systems, involving the use of modern sensor and communication technology and enabling more intelligent monitoring protection and control. This Special Issue on “Advances and Experiences in Protection Systems in Modern Power Systems” offer a space for researchers and developers to disseminate new solutions capable of addressing the actual challenges of protection systems in modern power systems, particularly those related to carbon neutrality.

Topics of interest include but are not limited to:

• Relaying philosophy for longitudinal power systems;
• Protection of power system elements;
• Control systems and special protection systems;
• Methods for calculation of settings of relaying systems;
• Analysis of protection operation during disturbances;
• Real-time monitoring for protection systems;
• Maintenance of relays and protection systems;
• Testing of relays and other elements of the protection system;
• Novel protective relay design;
• Current and potential transducers and communication channels;
• Digitalization of protection system and digital substations;
• Digital simulation of relays and other elements of the protection system;
• Manpower training in protective relaying;
• Cybersecurity of modern digital protection systems;
• Power-electronic-based technologies and effects on protective relaying applications;
• Wide-area monitoring, protection, and control;
• Impact of power quality problems on power system protection;
• Hardware in the loop simulation to test protection schemes in real scenarios.

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. Sustainability 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.
