Power Quality of Renewable Energy Source Systems

Dear Colleagues,

The power quality delivered by the distribution companies to consumers has always been a relevant issue, especially to industrial consumers where power quality is directly related to productivity. However, until a few years ago, power quality was mostly synonymous with continuity of service, the main concern was minimization of power interruptions. Since last decade of the twentieth century, the power quality has become a strategic issue for all sectors involved in this market, from distribution companies to consumers, with a particular emphasis on industrial consumers as well as equipment manufacturers.

The concept of power quality involves a wide range of electromagnetic phenomena that can occur in the power grid. Such changes may occur in different parts of the electrical power system, at customer facilities or in the distribution network. In recent years the electric power market has undergone huge transformations, electricity production has become decentralized and consumers (who can now also be producers) have the opportunity to choose their supplier. The integration of renewable-based microgeneration systems into distribution grids has brought various disturbances to the grid (harmonics, voltage unbalance, voltage fluctuations, frequency deviations, etc.), leading to increasingly degraded power quality.

This Special issue focuses on the analysis of the consequences that renewables-based microgeneration systems have on networks. Find new solutions for networks management (network optimization models, efficiency and losses), integrating consumers and micro-producers in order to keep quality parameters at high levels. The grid integration of Storage Systems and Electric Vehicles can also be addressed.

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 250 words) can be sent to the Editorial Office for assessment.

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.
