Multilevel Converters for Large-Scale Photovoltaic and Energy Storage Systems

Dear Colleagues,

The Guest Editor is inviting submissions for a Special Issue of Energies on the subject area of “Multilevel Converters for Large-scale Photovoltaic and Energy Storage Systems”.

In contrast to traditional power systems, the grid of the future will integrate large amounts of intermittent and stochastic renewable energy sources. Regulation of voltage and frequency in future grids will also likely be achieved in a decentralised but coordinated manner. This will lead to grids with a great deal of production and storage capacity that is directly connected to medium and high voltage parts of the network by means of power electronic converters. Given power electronic technologies will be responsible for the control of power between most renewable sources, energy storage devices and the grid, they will play a key role in the upcoming grid-transformation process.

Multilevel converters have become a standard for such applications as medium voltage drives, HVDC and FACTS and are promising for the integration of renewable energy sources and energy storage systems. Multilevel converters have the inherent benefits of high efficiency, excellent harmonic performance with reduced filtering requirements and the ability to be scaled in both voltage and current.

Given the increasing levels of photovoltaic penetration around the world, a large and effective grid-transformation process will require the advancement of the power electronic interface in large-scale photovoltaic and energy storage systems. Therefore, this Special Issue will focus on emerging power electronic technologies and applications in this area. Topics of interest for publication include but are not limited to:

• Novel multilevel circuit topologies;
• Power electronic modulation, control and optimisation;
• Power electronic grid support capabilities;
• Active submodule power balancing strategies;
• Common mode voltage/current utilisation in multilevel inverters;
• Fault-tolerant and reliable multilevel converters;
• Voltage source and current source converters;
• The role, design and optimisation of dc–dc conversion stages.

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.
