Strength and Stability of Renewable Energy Systems: Challenges and Solutions

Dear Colleagues,

Renewable energy sources, such as wind farms and solar systems, are increasingly integrated onto electricity grids via grid-connected power electronic devices. The asynchronous nature and low inertia of power electronics tend to weaken the energy systems, which brings new system stability issues and, in the worst-case scenarios, could lead to cascading failure and blackout events in response to disturbances. This Special Issue focuses on the technical challenges in system strength and stability and encourages innovative and breakthrough technologies to strengthen renewable energy systems. Topics of interest include but are not limited to:

• Technical challenges in weak grids with high power electronic penetration
• System strength modelling and assessment
• Non-network system strength enhancement
• Power system stability analysis and control
• Power electronics operation and control
• Integration of renewable energy into electricity grids
• Control and coordination of renewable energy sources
• Energy storage optimization and control
• Review of technologies for system strength analysis and enhancement

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.
