Recent Advances in Solar Photovoltaic Protection

Dear Colleagues,

Recently, there has been a rapidly growing trend towards the use of photovoltaic (PV) solar energy generation as a clean and easy-to-access energy source. As most PV components work in open environments, they are constantly subjected to environmental damage, including the destructive effects of chronic exposure to sunlight, dust, etc. This eventually leads to the improper operation of a PV system due to various faults and failures that can be either electrical, such as unintentional connections between two points with different voltage levels, or non-electrical, such as gradual cell or module degradation over a certain period of constant operation. The results can vary from a relative power loss in PV systems to catastrophic consequences, such as fire hazards. Hence, the protection of PV components is of particular importance.

Protection has conventionally been carried out using various electromechanical protection relays such as an overcurrent protection device (OCPD), a ground fault detector/interrupter (GFDI), a residual current device (RCD), an arc fault circuit interrupter (AFCI), etc. However, the performance of conventional electromechanical protection devices has proven to be unreliable when dealing with critical fault detection conditions. Consequently, an advanced automatic fault protection scheme is required to be able to protect the system against a wide range of faults in either critical or uncritical conditions.

Therefore, this Special Issue aims to publish high-quality papers on recent advances in the field of PV system protection, including the integration of artificial intelligence, digital twins, the Internet of things, etc. Potential topics include, but are not limited to, PV system fault detection, photovoltaic digital twin modelling, PV system predictive and preventive protection, PV system resilience and restoration, and recent techniques in photovoltaic feature engineering.

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. Solar is an international peer-reviewed open access quarterly 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 1000 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.
