Advances in DC Technology for Modern Power Systems

Dear Colleagues,

In the context of carbon neutralization, the integration of large-scale renewable energy sources is essential and will fundamentally shape modern power systems. DC technology is a promising solution for resolving the technical challenges associated with renewable energy integration due to its outstanding features, such as its capabilities of active control of power flow, power quality improvement, short-circuit current isolation and the prevention of possible cascading failures. There is substantial research on various DC apparatus; DC system operations, control and protection; and DC system modeling and simulation, which is currently developing worldwide. The objective of this Special Issue is to promote the research, innovation and application of the key challenges and enabling technologies for the development of DC technology in modern power systems.

Topics of interest for publication include, but are not limited to:

• Converter technologies;
• Architectures of DC grid and hybrid AC–DC grids;
• DC system protection and grounding;
• Stability issues for power electronics-intensive DC grids;
• Modeling and simulations of DC systems;
• Power flow, voltage and frequency support, ancillary service provision of DC systems;
• Operation, dynamic and control of DC systems;
• Power quality problems;
• Demonstration and laboratory projects of DC 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. Energies 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 2600 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.
