Dear Colleagues,

The primary objective of a power system is to safely provide reliable energy services to society at an affordable cost. Achieving this objective must be done according to a fast transformation from fossil to sustainable energy sources, new paradigms for transmission, distribution, and consumption. Existing power system analysis and planning methods are potentially compromised by the rapid transition occurring globally, characterized by the increasing penetration of variable renewable energy (VRE), inverter-based resources (IBR), and distributed energy resources (DER). New analysis and planning methods must also consider the flexibility of the electric power system—often defined as the ability to cope with variability and uncertainty.

This Special Issue is focused on new approaches for power system analysis and planning accounting for technical and economical challenges to the transition to a decarbonized and sustainable environment. Contributions to this Special Issue are expected to address the most relevant challenges of today’s power system operation and planning.

The main topics of interest for this Special Issue include but are not limited to:

• Power system analysis approaches including variable renewable energy (VRE), inverter-based resources (IBR), and distributed energy resources (DER): power flow, short-circuit, frequency and voltage stability, hosting capacity, and static and dynamic state estimation;
• Power system analysis/dynamics for facilitating the connection of electric vehicles and storage devices;
• Integration of renewable energy at transmission- and distribution-level considering flexibility resources.
• Planning of flexibility resources in different timescales; demand side management, energy storage systems, and thermal rating of equipment, among others;
• Stochastic models for generation, transmission, and distribution planning
• Optimization approaches, network models, short-long-term approaches, etc. Transmission, generation and distribution planning and analysis;
• Methodologies, models, and tools for planning: interconnection studies, unit commitment and production cost studies, planning of flexibility resources;
• Planning of HVDC grids and links;
• Joint expansion planning of power systems and other energy networks as gas pipelines.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Sustainability 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.
