Symmetry in Renewable Energy, Power Systems and Power Quality III

Dear Colleagues,

The study of power systems is closely related to symmetry; e.g., multiphase power systems are inherently symmetric. The study of symmetrical and asymmetrical faults in power systems is a critical issue. The phase sequence arrangements of multicircuit overhead lines on the same tower directly affect power transmission system symmetry, influencing power grid operation and relay protection. Moreover, the field of symmetry is under intensive investigation in the analysis of grid interconnection, including symmetrical and asymmetrical network parameters in smart grid infrastructures. In the area of renewable energy, symmetry is present in the layout of wind power plants and photovoltaic plants, while solar systems’ different performance may be improved with symmetric and asymmetric concentrating CPC collectors.

This Special Issue invites researchers to submit original research papers and review articles integrating renewable energy and power systems with a consideration of theoretical or practical issues of symmetry. Applied case studies are especially welcome. Topics of interest include, but are not limited to:

• Symmetry in the topology of power grids;
• Symmetry in multiphase/polyphase power systems. Power network synchronization;
• Effect of symmetry on power quality of smart grids and distribution networks.
• Symmetric and asymmetric components;
• Symmetrical and asymmetrical faults in power systems;
• Symmetry analysis of phase sequence arrangements of multicircuit overhead lines;
• Symmetry studies of electrical signals using signal processing methods (FFT, DFT, STFT, WT, Wavelet...);
• Symmetry in power electronics devices and renewable energy components;
• Symmetry in renewable energy systems (including smart grids and microgrids);
• Symmetrical analysis of power plant layouts and location (including wind farms and photovoltaic plants);
• Algorithms for studying symmetry in renewable energy and power systems;
• Synchrophasor estimation algorithm for monitoring the symmetry of smart grids.

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. Symmetry is an international peer-reviewed open access monthly 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.
