Dear Colleagues,

Over the past decade, the increasing integration of inverter/converter interfaced power sources (e.g., wind power, solar power, battery technologies) has posed new challenges to power systems. An important one is the reduction of system inertia, which is the significant ability to maintain power system stability and resiliency. Subsequently, power system operation, stability, and resiliency will be critically affected, causing frequency/voltage oscillations, instability, and cascading failures.

One of the solutions toward stabilizing such power systems with massive renewable energy sources (RESs) and distributed generator (DG) penetration is by synthesizing additional inertia and damping properties virtually. This new concept is known as virtual inertia control, which has opened up new possibilities to monitor and control such a challenge. Control techniques such as virtual inertia and damping controls provide a key for maintaining a high share of RESs/DGs in future power systems without compromising system stability and resiliency.

This Special Issue deals with the design, operation, and control of interfaced systems between RESs/DGs and power grids to guarantee the secure stability of systems. This issue will serve to stimulate further research and to offer practical solutions to real-world power system stability and control problems with respect to system inertia variation triggered by the integration of RESs/DGs.

Submissions are invited from researchers and practitioners working in related areas, and to promote a venue for cutting-edge fundamental and applied research related to future grid control technology. In this context, the guest editor invites experts in this field to contribute original and unpublished papers to this Special Issue dealing with but not limited to the following research areas:

• Design, control, and analysis of virtual inertia systems for renewable energy integration
• Stability assessment of power systems under high renewable integration
• Voltage stability analysis with high renewable integration
• Frequency stability analysis with high renewable integration
• Oscillatory stability analysis with high renewable integration
• Power system protection for enhancing renewable integration
• Ancillary services and active management techniques with high renewable integration
• Optimal system planning, scheduling, and coordination methods to increase high renewable integration
• Intelligent control and innovative hardware solutions for large-scale grid integration of distributed generation and flexible loads
• Application of artificial intelligence and machine learning approaches for grid stability improvement
• Design, control, and analysis of active power system networks
• Grid support functions and ancillary services from renewable energy power systems, centralized, and decentralized/distributed techniques
• Reliability assessment with renewable integration

If possible, I also highly recommend multimedia submission with each article as it significantly increases the visibility, downloads, and citations of articles.

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.
