Advanced Sensing Technologies for Grid Monitoring, Protection, and Control

Dear Colleagues,

Amid the accelerated low-carbon transition of the global energy system, the integration of large-scale renewable energy, distributed resources, and diversified loads into the power grid is driving the continuous evolution of traditional power grids toward the "New-Type Power System." During this transformation, the New-Type Power System has gradually presented a series of challenges, such as declining inertia, the emergence of bidirectional power flows, and increased operational uncertainty—thereby imposing higher demands on the grid’s capabilities in real-time perception, rapid response, and precise control. In this context, advanced sensing technology, as a core technology for building the smart grid, not only serves as the key foundation for accurate grid status perception, rapid fault location, and self-healing control, but also drives profound changes in the operational model of the New-Type Power System across multiple dimensions.

Specifically, the transformative role of advanced sensing technology is primarily reflected in three dimensions: monitoring, protection, and control. In terms of monitoring, it expands the scope of perception, enabling panoramic monitoring of operational status and early warning of potential risks. In terms of protection, by capturing transient fault signals in real time, it helps protection systems realize a leap from "passive response" to "active defense." In terms of control, as a key component of the generalized closed-loop system, it enables dynamic adaptive control based on real-time status information—significantly enhancing the system’s controllability, operational stability, and security.

To facilitate technical exchange and innovative practices in this field, this Special Issue aims to showcase the latest research advances and typical engineering applications of advanced sensing technology in grid monitoring, protection, and control. We kindly invite authors to submit their contributions to this Special Issue, focusing on topics including, but not limited to, the following:

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. Sensors 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 2600 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.
