Applications of Medium Voltage Direct Current in Electric Systems

Dear Colleagues,

Electric power systems will need to accommodate large amounts of renewable energies and a growing number of DC loads with reduced costs and losses. The medium-voltage direct current (MVDC) grid concept can play a key role, since it can help reduce the number of conversion stages necessary for the integration of the low voltage output from a renewable generation source to the electricity grid, which operates at a much higher voltage. Furthermore, these same efficiencies are achieved in end-use applications for the increasing supply of DC loads in power grids. Therefore, MVDC architecture can serve as an additional stage of infrastructure in the electricity grid between transport and distribution levels, as well as a means to supply consumers of all kinds. Thus, MVDC is an enabling architecture in commercial, residential, industrial, generation or transportation sectors for the grid integration of renewable energies, energy storage systems, supply of DC loads, and future needs in the field of energy conversion systems among other possibilities.

This Special Issue is focused on the recent advances in the applications of MVDC in electrical systems, and includes, but is not limited, to the following topics:

• MVDC for smart grids and microgrids.
• MVDC for utility distribution networks.
• MVDC in electric transportation.
• MVDC in industrial application.
• Renewable energies with MVDC.
• Energy storage systems with MVDC.
• Power electronics for MVDC.
• Control techniques and energy management systems for MVDC grids.
• Power quality in MVDC grids.
• State-of-the-art reviews on MVDC applications.

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.
