Special Issue Information

Dear Colleagues,

The scope of this Special Issue covers all issues in the electrical and electronics engineering background like power converters, power supplies, grid connected inverters and battery charger circuits. The final goal is achieving the high sustainability in electrical and electronics engineering. The field of electrical and electronics engineering is also experiencing this transit of power converters, power supplies, grid connected inverters and battery charger circuits, where we need further consideration of how this change and sustainability matters can be harmonized.

The Special Issue will address practical and theoretical issues associated with Sustainability in electrical engineering. Topics of interest include, but are not limited to the following:

  • Power converters;
  • Switching mode power supplies;
  • Grid-connected inverters;
  • Power electronics;
  • Sustainability in electrical engineering;
  • Battery-charging circuits;
  • Issues in electrical engineering;
  • Power systems.

We look forward to receiving your contributions.

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. Sustainability 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.

For remote offshore wind farms, transmitting power to the main onshore grid via a Voltage Source Converter High Voltage Direct Current (VSC-HVDC) system is the mainstream of power transmission. It is not only cost-effective in long-distance transmission, but also can fully meet the grid side requirements such as black start, voltage support, fault ride through and frequency support. However, it still has some problems, such as the possible impact on the power grid needing to be paid attention to. In this paper, its impact on the torsional responses of turbine generator units neighboring to the onshore side of AC bus is studied by using the DIgSILENT PowerFactory software. It is found that the effects of the Sub-Synchronous Torsional Interaction (SSTI) with onshore controls and the generator de-rating operations can significantly affect the damping ratio of turbine torsional modes, whereas the effects of the machine configurations and the amount of wind farm power integrated can affect the electrical torque disturbance. The most noteworthy is that their effects can be superimposed on each other if these factors act simultaneously, which would lead to increased vibrations and reduce the turbine shaft’ s life. The findings will be helpful for avoiding accidents caused by torsional vibrations when it is going to integrate a VSC-HVDC connected wind farm into a power grid. Full article

The aim of this study is to draw a comprehensive image of the relationship between life cycle sustainability assessment (LCSA) impact using the three dimensions, namely life cycle costing (LCC), life cycle assessment (LCA), and social life cycle (SLC), and solid oxide fuel cells (SOFCs). By systematically reviewing and analyzing 43 articles from 17 different peer-reviewed journals between 1998 and 2021, the analysis shows that SOFC-related applications may substantially contribute to a cleaner energy sector in the future via high-level temperature power generation. The result indicated that SOFCs have better implications for environmental performance, as well as being the least cost-effective option for commercially competitive purposes. The review revealed several gaps in the literature; several studies assessed LCA using particular or very few indicators, and the few indicators may not sufficiently assess the environmental impact of SOFCs. Further, limited studies shed the light on the association between SLC and SOFCs. Future LCSA studies ought to adopt dynamic criteria, especially environmental impact analysis considering social and economic factors, to enable a feasible comparison of results. Future studies should also target various industrial sectors in developing countries. Full article
