Special Issue Information

Dear Colleagues,

The electrical power system can be regarded as a comprehensive symmetrical system of power supply and power consumption, with load microelectronics technology being the core of many new technologies, emerging industries, The most common PQ events are associated with sags (dips), harmonics/interharmonics, transients, and asymmetrical variations. PQ is related to the safe and stable operation of power systems and users' high-quality electricity consumption. Therefore, the monitoring, prevention, and mitigation of PQ disturbances are of great concern for both parties. To achieve these goals, the study of many PQ issues and their methods of analysis remains a challenging task. Moreover, with the widespread use of power quality monitoring tools, more and more users and developers are starting to realize that power disturbances can carry valuable information about the conditions of a system and its equipment. As a result, initiatives that explore the “useful” aspects of power disturbances using power big data have emerged.

The topics of interest for this planned issue of Symmetry include but are not limited to:

  • Voltage sag perception, warning, location and treatment technology;
  • Transient characteristic analysis of AC/DC power grid under voltage sag conditions;
  • The division of harmonic responsibility;
  • Harmonic power flow algorithms considering distributed generation;
  • Study of generation, propagation characteristics and influence of ultra-high harmonics;
  • Harmonic source load identification;
  • Three-phase imbalance management;
  • Power quality data application;
  • Power quality in integrated energy systems;
  • The modeling of power quality interference sources;
  • The optimization and management of power quality problems in new power systems;
  • Three-phase unbalanced power flow analysis technology;
  • Power quality analysis and economic research.

Manuscript Submission Information

Manuscripts should be submitted online at 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.
