Power Quality Monitoring with Energy Saving Goals

Dear Colleagues,

The energy transition that we are currently witnessing and the constant increase in demand for electricity mean that issues related to power quality are becoming ever-more critical. Power quality is described as a set of parameters describing the properties of a process of supplying energy to the user under normal operating conditions, determining the continuity of the power supply and characterising the supply voltage. However, the power quality is also related to the receivers’ parameters, such as the harmonic content in currents or absorbed reactive power. These parameters significantly affect voltage degradation and are essential due to losses in energy transmission. Monitoring power quality factors and appropriate decision-making processes or devices can, therefore, impact energy savings by reducing losses. In addition, monitoring quality parameters in the electrical grid can prevent costly failures or predict the production downtime. The measurement results of the analysed grid provide a base for power grid optimization processes involving solutions (e.g., active power filters, UPFCs, compensators) that improve the power quality and reduce losses.

In summary, this Special Issue will collect articles and review papers related to the monitoring and measurement of power quality parameters to save energy. Since monitoring alone does not give any results without further actions, it is also necessary to consider technical solutions, i.e., devices and processes that use the obtained measurements and generate direct or indirect energy savings.

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.
