LTE Development for Enabling Smart Grid Services

The term “smart grid” refers to a two-way communication network for electricity grid where devices wirelessly connected are able to remotely detecting status of electricity generations, transmission lines and substations, monitoring consumption of user electricity usage, adjusting the power consumption of household applications to conserve energy, and reduce energy losses.

The smart grid has been proposed as an alternative to the traditional electricity grid thanks to its exceptional advantages of real time control on consumption demands. Massive distributed energy micro-generation, through small-scale renewable energy sources, is replacing the traditional utility-consumer paradigm with that of a wireless networked ecosystem of multiple energy pro-sumers (energy producers and consumers), where thousand wireless devices can be used to monitor and control the smart grid.

The latest wireless network, 3GPP Long Term Evolution (LTE), is considered to be a promising solution for smart grids because it provides both low latency and large bandwidth. Recent machine-to-machine M2M and other developments in the latest LTE Releases have the potentiality to address challenges such as the large population of networked smart-grid devices, the ultra-high aggregate volume of smart-grid data and their mission-critical nature. However, LTE was not originally intended for smart grids applications, where data generated by the grid have specific delay requirements that are different from traditional data or voice communications. This seed research project, DevelopLTE4Grids, aims at filling this technological gap through an LTE/LTE-A wireless infrastructure.
