Dear Colleagues,

Electrical utilities and customers are interested in enhancing the quality of the generated and distributed electrical energy. The main aims are to produce clean electrical power and to distribute it to the end customers with acceptable power quality performance in a cost-effective manner. At present, the importance of power quality has increased because of the booming developments in various power-electronic devices and renewable energy resources under the umbrella of smart grids. Consequently, power quality plays an essential role in modern electrical power systems. In its broadest sense, power quality is a set of constraints that allow electrical systems to operate with reliable, secure, and continuous good quality of power with no additional loss of performance due to any abnormalities. However, new challenges and opportunities have emerged in modern systems’ power quality performance. Consequently, a great deal of attention should be paid to power system quality in order to meet the future system requirements, particularly with the unprecedented large-scale integration of renewable energy sources in electrical systems. If the renewable energy sources are not adequately allocated, it may lead to various voltage and power quality problems. Therefore, novel solutions must be sought to enable networks to cope with these developments in order to realize resilient power networks that can host high renewable penetration while ensuring acceptable power quality performance.

In this Special Issue, we are calling for original contributions that cover the emerging challenges in power quality in modern power systems. It is our pleasure to provide a platform to bring together university scientists, researchers, and leading researchers to share their thoughts, ideas, experiences, and research results on all aspects of the power quality of modern electrical systems and smart networks.

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. 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.
