Modeling, Security Analysis and Optimized Operation of New Power Systems

Dear Colleagues,

Against the backdrop of the global energy transition and increasingly ambitious carbon-neutrality goals, power systems are undergoing a profound transformation characterized by high penetration of renewable energy sources, extensive integration of distributed resources, and growing interdependence with multiple energy sectors. This evolution introduces unprecedented complexity and uncertainty into system operations, posing significant challenges to traditional modeling paradigms, security assessment frameworks, and control strategies. Ensuring the secure, stable, economical, and low-carbon operation of this new power system has become a critical and pressing global issue.

Advanced modeling, precise security analysis, and intelligent optimization constitute fundamental pillars for understanding, managing, and enhancing the performance of future grids. They form the essential foundation for achieving situational awareness, enabling adaptive protection, and implementing resilient control in environments increasingly dominated by power electronics and stochastic generation.

This Special Issue aims to compile the latest research and innovative solutions addressing core challenges in modeling, analyzing, and optimizing the operation of new power systems. It seeks to advance both the theoretical foundations and practical methodologies that underpin a secure and efficient grid transition. We invite the submission of high-quality original research and review articles. Topics of interest include, but are not limited to, the following:

1. Novel modeling frameworks for new power systems integrating renewables, storage, and active demand.
2. Dynamic security assessment and stability analysis for power-electronics-dominated systems.
3. Data-driven and AI-based methods for system state estimation, situational awareness, and security forecasting.
4. Optimization models and algorithms for low-carbon, economic, and secure dispatch under high uncertainty.
5. Fault analysis, characteristic extraction, and resilience assessment for new power systems.
6. Advanced protection schemes, including wide-area protection and adaptive relaying, for complex fault conditions.
7. Co-simulation and hybrid modeling techniques for coupled cyber–physical power systems.
8. Coordination of protection, control, and converter strategies to enhance system security and resilience.
9. Risk-based operational planning and real-time decision-making frameworks.
10. Case studies, practical applications, and performance evaluations of new methodologies in real-world or large-scale test systems.

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. Electronics 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.
