Power Electronics for Renewable Energy Systems: Latest Advances and Prospects

Dear Colleagues,

The introduction of renewable energy sources changes the power grid at its core from a predictive unidirectional energy flow to a varying and bidirectional flow. Production must always be balanced against consumption to keep the grid frequency stable and voltage requirements must be fulfilled in all parts of the grid. With these major challenges comes the amount of waste power, in generation, distribution, and by the end-user. Power conversion is required at both the generator and load sides, often required handling bidirectional power flow. To account for sudden and unpredictable variations in production short term energy storage is becoming a very important source for grid stabilization. Clouds passing over solar power installations can create large voltage variations for nearby customers as a result of sudden reversed power flow direction that can be stabilized with line voltage regulators and dynamic voltage restorer. Flexible AC transmission systems are important for maximizing the power utilization in the system and controlling the power flow in the grid. 

This Special Issue addresses all aspects of requirements, design, development, reliability, market opportunities, etc., for electronics of renewable energy systems.

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. Electronics 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.
