Special Issue Information
Dear Colleagues,
The advancement of power systems is mainly driven by the integration of renewable energy sources (RES) and energy storage systems (ESS), in parallel with the evolution of network architectures that host RES and ESS, especially toward DC and hybrid AC/DC architectures. This ongoing transformation requires robust, efficient, and intelligent solutions in order to provide reliable and sustainable energy in different contexts, such as buildings, microgrids, and urban energy districts.
Current challenges related to RES and ESS comprise the conception of new hybrid topologies and conversion systems, as well as the development of new control strategies to achieve smarter grid interaction. Likewise, the use of emerging DC and DC/AC networks featuring power equipment such as lines and converters needs to revisit several aspects such as their modeling, system operation and management, protection, and diagnostics.
This Special Issue seeks to gather contributions that address these challenges through novel technical solutions and methodologies, as well as applied experiences and real-world applications. We welcome theoretical, design, modelling, experimental, and implementation studies.
Topics of interest include, but are not limited to, the following:
- Smart DC and hybrid AC/DC networks (LVDC, MVDC, HVDC);
- Photovoltaic systems, hybrid PV–wind systems, and novel topologies;
- Modelling and simulation of buildings, microgrids, and positive energy districts with RES and ESS integration;
- Urban renewable-energy architectures and positive energy districts;
- Geothermal energy networks and hybrid strategies featuring geothermal energy;
- Energy management for residential, commercial, and urban environments;
- Energy storage systems and strategies for networks with high renewable penetration;
- Control and optimization methods, including AI-, ML-, and fuzzy-logic-based approaches;
- Diagnostics, monitoring, and fault-tolerant operation of power equipment, including RES and ESS systems, power converters, electrical machines and drives, or power lines;
- Protection, stability, and resilience of DC and AC/DC hybrid grids with a strong presence of RES or ESS;
- Power electronic converters for RES and ESS integration, topologies, and dynamic control;
- Power generation in urban environments and microgrids;
- Diagnostics and advanced monitoring of PV systems;
- Electrical machines in distributed generation, conversion, and grid-support applications;
- Renewable energy solutions for neutral urban systems and cities;
- Power generation and conversion in smart cities and microgrids.

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. 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.
