Innovative Strategy of Protection and Control for the Grid

Dear Colleagues,

Although the pairing of energy storage systems with a renewable energy source ensures a smooth and steady power supply, particularly in the case of unfavourable weather conditions, high integration of smart grid renewable energy resources produces more challenges for the reliable operation of the grid. The impacts of the loss of a portion of the electric grid range from minor inconveniences for most users (when the outage is on a small scale and short-lived) to potentially catastrophic situations (when the blackout covers a large region for a long duration). There is usually a trade-off between a reduced blackout risk and increased cost. The focus of this Special Issue is on the development of a coordinated protection and control scheme for the system, which reduces risk and improves grid resiliency. The post fault stability concerns will be a part of the decision-making process while addressing the protection issues, and hence, disastrous consequences can be avoided with minimum time delays. Moreover, this Special Issue also focuses on the seamless integration of energy storage with an existing grid with considerable penetration of renewable energy resources, leading to its universal deployment. As the deployment of battery storage, PV and wind generation is rapidly increasing, their optimal allocation would certainly improve grid resiliency during extreme events. Therefore, a new multi-objective optimization approach will be required to decide the optimal sizing and location of battery storage, PV, and wind generation for improved system resilience.

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. Inventions 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 1800 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.
