Special Issue Information
Dear Colleagues,
The Special Issue "Novel Ideas for Multiterminal HVDC Grid Protection and DC Circuit Breakers" seeks technical as well as scientific papers addressing protection schemes and circuit breakers for high-voltage DC transmission systems. In an era when fossil fuel reserves are depleting, along with energy demands increasing, renewable energy sources must be integrated into the grid. In addition, most future offshore wind farms will be far from load centers, so multiple DC connections will be necessary. Several studies have shown that a conventional HVAC transmission becomes infeasible beyond a certain distance when connecting renewable energy sources and load centers. Multiterminal HVDC (MT-HVDC) networks are expected to become more prevalent in the future, with DC faults considered to be a significant limitation. Identifying, classifying and locating DC faults within large networks and isolating faulty parts are challenging tasks. Moreover, HVDC circuit breakers are required to interrupt the abrupt rise in DC fault currents. Thus, flexible MT-HVDC grids require efficient protection schemes and effective HVDC circuit breakers. The following are potential topics included, but not limited to, in this Special Issue’s scope:
- The contingency analysis, design and development of HVDC systems, including converter stations, DC–DC converters, semiconductor devices and transmission links;
- Multiterminal HVDC transmission grid faults;
- HVDC grid control and operation during faulty conditions;
- Protection algorithms and relay modeling;
- Hybrid HVDC grid faults and DC grid fault analysis;
- Fault current limiters;
- HVDC circuit breakers.

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. Applied Sciences 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.
