The International Conference on Renewable Energies and Smart Technologies (REST-22)

Dear Colleagues,

Due to environmental and sustainability concerns, power systems worldwide are in the middle of a rapid transition. Large conventional generators are being phased out and replaced with mainly converter-interfaced renewable energy sources (RESs) such as wind power and solar photovoltaic.

The dominance of converter-based generation in modern power systems poses new stability issues and requirements for the controls due to the different physical characteristics and interaction with the grid of converter-interfaced components. A way to integrate RESs into power systems is through the concept of smart grid technology. However, safely and securely integrating large shares of variable RESs is still a challenge for most power systems. There is a need to replace the ancillary services provided by conventional generators, such as inertial, primary, and secondary voltage and frequency control. On the other hand, current electricity markets were designed on concepts developed for a generation fleet that was predominantly conventional fossil fuel. Therefore, there is a need for redesigning these markets and successfully integrating high levels of RESs.

This Special Issue focuses on the latest developments in renewable energies and smart technologies. In particular, the Special Issue targets applied research from both academia and industry on the following topics:

• Conventional and innovative inertia-based RESs, e.g., hydropower, tidal
• Inverter-based RESs, e.g., wind and solar
• Impact of RESs on power system dynamics
• Frequency regulation and control under high penetration of RESs
• Security of supply and generation adequacy in renewable-based systems
• Integrating RESs into existing and new electricity markets
• Decision-making under uncertainty in electricity markets
• Integration of distributed energy resources
• Control and management of RESs
• Network digitalization and smart metering infrastructures
• Distribution grid observability, automation, and supply quality
• Protection schemes, islanding, and microgrids operation
• Decentralized and distributed control solutions for energy systems
• Flexibility services and demand response programs
• Black start capability and emergency power reserves
• Grid modeling and simulations
• Energy storage and applications
• Grid forming and following converter control
• Ancillary services from inverter-based generators, i.e., voltage and frequency control, fast fault current injection

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 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. Applied Sciences 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.
