A Review of Wireless and Satellite-based M2M Services in Support of Smart Grids

Abstract

The Smart Grid (SG) is an evolution of the electricity network that integrates the activities of power consumers, power generators, distribution grid, and devices connected to the grid (e.g., substations, transformers.) Machine-to-Machine (M2M) technology is designed for automated data exchange between devices, and thus has applicability to SGs. With M2M technology, organizations track and manage assets; inventories; transportation fleets; oil and gas pipelines; mines; widespread infrastructure; natural phenomena such as weather conditions, farm production, forestry condition, and water flows; and, as noted, SGs. Wireless communication is a staple of M2M. These wireless technologies range from unlicensed local (so called 'fog') connectivity, to licensed 3G/4G/5G cellular, to Low Earth Orbit (LEO) satellites. All of these technologies are relevant to the SG. Utilities have started to gradually support M2M and Supervisory Control And Data Acquisition (SCADA) systems over satellite links. This article focuses on wireless and satellite-based M2M services, as applicable to the Smart Grid, including the use of Internet of Things (IoT), particularly for the transmission and distribution space (T&D) sector; some comparisons to wireline solutions are also discussed.

WSN-Based Measurement of Ion-Current Density Under High-Voltage Direct Current Transmission Lines

“…The next-generation electric power system, smart grid, requires continuous devices monitoring, examining and completely controlling the overall grid, thereby allowing big data analytical services to forecast and evaluate the status of grid [18]- [21]. Internet of Things (IoT), or the interconnected web of technologies, is a network of such objects through which they can collect and exchange information.…”

IoT Applications to Smart Campuses and a Case Study

“…Applications range from infrastructure and critical-infrastructure support (for example smart grid, smart city, smart building, and transportation) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], to end-user applications such as e-health, crowdsensing [21], and further along, to a multitude of other applications where only the imagination is the limit (noting that the references included are only a miniscule subset of the available literature). Some refer to the field as "connected technology".…”
