Technological Horizons in High Voltage Engineering: Towards the Power Systems of the Future

Dear Colleagues,

High-voltage equipment has always been a basic element for human technology since it makes it possible to safely transform, transmit and convert electrical energy and to make it available for industrial and domestic utilization.

Moreover, in the times we are living in, most countries are dealing with the energy transition from fossil energy sources to renewable energy ones, with the aim of mitigating the carbon dioxide emissions to, in turn, attempt to mitigate environmental changes and their impacts, and ultimately to preserve the people’s health. In order to effectively achieve this noble and ambitious purpose, high-voltage engineering plays a key role in enabling such a massive penetration of renewable energies into power systems and, at the same time, to guarantee its safe operation.

Hence, this Special Issue offers an important opportunity to publish advances and the state-of-the-art in the high-voltage engineering field, together with research trends for the future developments.

More specifically, topics of interest include (but are not limited to) the following:

• Advances in high-voltage technologies such as relays, transformers, cables and overhead lines, insulated gas lines and insulated gas substations;
• Advances in power conversion systems to develop more efficient HVDC connections;
• In-field experience and experimental evidence arising from practical applications of high-voltage engineering;
• Advances in superconductive technologies;
• Advances in testing high-voltage equipment;
• Innovative strategies to manage the power systems, such as to support the frequency and voltage regulation of transmission networks and new approaches to avoid transmission line congestion;
• Innovative modelling approaches to foresee the behaviour of power systems;
• Overviews which clearly show the state of the art of a particular high voltage technology;
• Modelling, advances and applications in flexible technologies, such as FACTS (Flexible AC Transmission System), DLR/RTTR (Dynamic Line Rating/Real Time Thermal Rating) and HVDC (High-Voltage Direct Current) devices;
• Advances in high-temperature, low-sag conductors;
• Modelling and implementation of innovative transmission technologies towards regional, continental and trans-continental applications and studies;
• Transmission evolution and transition for RES integration and exploitation towards the decarbonisation pattern.

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-anonymized 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.
