Symmetry and Stability in Advanced Power and Energy Systems

Dear Colleagues,

The relentless growth in energy demand, coupled with the imperative for decarbonization, is driving a profound transformation of power systems worldwide. The large-scale integration of intermittent renewable energy sources and the rapid adoption of electrified transportation, particularly Electric Vehicles (EVs), present unprecedented challenges to the stability, reliability, and efficiency of the grid. These modern energy systems are inherently complex and dynamic, requiring advanced methodologies for their analysis, control, and optimization.

In this context, the principle of symmetry offers a powerful and elegant framework. From the fundamental theory of symmetrical components in fault analysis to the symmetrical structures in power electronic converters and the balanced operation of three-phase systems, symmetry is a cornerstone of power engineering. However, new asymmetries introduced by distributed generation and unbalanced loads must be managed to maintain overall system stability. This Special Issue, "Symmetry and Stability in Advanced Power and Energy Systems," aims to explore the intricate relationship between symmetrical principles and the stable operation of next-generation power and energy networks.

We invite the submission of high-quality research articles and comprehensive reviews that address the challenges and innovations at this intersection. Topics of interest for this Special Issue include, but are not limited to, the following:

• Stability analysis and control in power systems;
• Symmetrical components and their applications in modern grids;
• Advanced control strategies for renewable energy integration (solar, wind, etc.);
• Planning, operation, and control of energy storage systems;
• Power electronics for grid stability and power quality;
• Electric vehicle grid integration (V2G) and its impact on system symmetry and stability;
• Optimization and optimal control in hybrid energy systems;
• Resilience and cyber-security of symmetrical power architectures;
• Digital twins and real-time simulation for stable power system design;
• Probabilistic and AI-based methods for stability assessment.

We look forward to receiving your innovative contributions.

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. Symmetry is an international peer-reviewed open access monthly 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.
