Dear Colleagues,

The Guest Editors are inviting submissions to a Special Issue of Energies on the subject area of “Modeling and Mitigation of Reliability Issues in Power Converters for Modern Power Grids”.

In recent times, there has been a strong determination to implement microgrids (MGs) as alternatives to conventional grids. In MGs, there are different power-electronics-based power sources that gather energy from renewable energy sources and also provide bidirectional power flow for storage devices. Thus, power electronic converters are used in wide ranges of power levels, voltage, and current rates for AC and DC MGs. With progress in the manufacturing technology of power converters, gird-connected interfaces for the distributed power sources have been developed in recent decades. By increasing the roles of power converters in MGs, providing continuous and reliable conditions for feeding vital and high-power applications must be attained by researchers and network owners. Therefore, the reliability challenges of power converters are becoming an important issue. Photovoltaic and wind power systems, energy storage devices, and electric vehicles are starting to have important roles in future MGs. Different types of inverters, DC–DC converters, and unidirectional/bidirectional chargers must be designed from a reliability standpoint to guarantee fault-free operation during their lifetime and provide alternative solutions to unexpected events.

We are certainly aware of the technical, economic, and industry-based reliability challenges of power converters for modern MGs and are open to contributions on these aspects. We cordially invite you to submit your original works and research papers to this Special Issue. Potential topics include but are not limited to:

• Fault diagnostics, prognostics, and mitigations for power converters;
• Lifetime model formulations for power components;
• Fault-tolerant strategies and designs;
• Real-time health conditions of circuit elements;
• Identification and introduction of different factors that impact the reliability of power converters;
• Heat sink approaches and cooling system designs;
• Reliability-driven multiobjective design optimization of power converters;
• Practical reports of reliability issues in power converters of transportation electrification segment, including but not limited to electric vehicles, electric ships, and more electric aircrafts;
• Review papers related to the reliability and fault-tolerant capability of power converters;
• Software tools for reliability analyses;
• Artificial Intelligence applications for reliability-based design of power electronic systems.

Content Types

Regular Paper:

New results in the field of reliability issues of power converters which are applicable for modern power grids: for example, reliability issues of power components, devices, module, system-level, circuit, control, system, or application issues.

Letter:

This type of papers gives authors the opportunity to publish contributions within less than one month of submission to ensure rapid dissemination of their original ideas. This option let the authors record their ideas rapidly, even more rapid than conferences. Then the authors can publish a fully extended version of their work in scientific journals. 2–6 pages (excluding references) limitation is recommended for this type of papers.

Technical Reports:

One of interesting type of papers which are welcomed is "Technical Reports". Experts in industry may face with reliability issues in their case studies, present solutions for those issues. The gust editors say welcome to hear their technical reports. Because, providing experiment insight for researcher is very valuable.

Review Paper:

Review papers are always interesting articles for researcher to know the last progress in a filed. This type of papers can be written by experts, who have defined their Ph.D./MSc courses with their supervisions, and anyone know very well the research and technical developments in the field to provide a guidance map for future steps.

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 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. 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.
