Control and Optimization Processes for Renewable‑Dominated Power Systems

Dear Colleagues,

The rapid transition to renewable-dominated power systems marks a fundamental shift in how electricity grids are planned and operated. Unlike conventional systems anchored by synchronous generators, these new grids feature high shares of power electronics, low inertia, and considerable generation uncertainty. While essential for decarbonization, this evolution poses serious challenges to system flexibility, stability, and security. Traditional control and optimization frameworks, designed around predictable generation, are ill-suited to handle the multi-timescale dynamics processes and variability of modern renewables. There is therefore a pressing need to develop novel theories, algorithms, and architectures that can fully harness the agility of renewable energy resources to support the safety and efficient operation of power systems.

This Special Issue aims to showcase cutting-edge research on control and optimization strategies for renewable-dominated power systems. We invite contributions that address foundational theories, advanced methodologies, and real-world implementations for improving flexibility, stability, and cost-effectiveness. We particularly encourage work that transcends conventional generation–transmission–distribution boundaries and offers integrated solutions coordinating diverse adjustable assets—from large-scale wind/solar plants and storage systems to demand-side flexible loads.

Topics of interest include, but are not limited to:

• Multi-timescale modeling, simulation, and analysis of flexibility and stability;
• Stochastic optimization for dispatch, unit commitment, and real-time operation under uncertainty;
• Grid-forming control and active frequency/voltage regulation for converter-interfaced renewables;
• Damping control and oscillation mitigation;
• Data-driven, AI/ML, and digital-twin methods for state awareness and predictive control;
• Co-optimization frameworks addressing the coupling between flexibility reserves and stability margins;
• Hierarchical and distributed coordination of storage, EVs, flexible loads, and other adjustable resources;
• Market design, demand response, and transactive energy that align economic incentives with grid security.

We warmly welcome original research and comprehensive reviews from academics, engineers, and policymakers. Through this collection, we hope to foster cross-disciplinary dialogue that charts a clear path toward the sustainable, resilient, and efficient power systems of the future.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes 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.
