During the last years, the installation of Distributed Energy Resources (DERs) and the expected diffusion of Electrical Vehicles (EVs), is increasing the complexity of the distribution grid, making the management of the grid operated by Distribution System Operators (DSOs) more difficult. The Smart Grid approach tries to provide a response to these troubles, by means of a strong interaction between...
Smart Grids require a pervasive communication network to interconnect their intelligent devices (e.g. generators, protections, and meters) that are usually distributed over a wide area. Recently, the Long Term Evolution (LTE) wireless cellular network communication technology has been introduced and its diffusion is rapidly increasing. As a consequence, LTE may be considered as a viable opportunity...
In the last years, the increasing focus on energy savings is the key factor in the transformation of the legacy distribution grid toward the so called smart grid. One of the most evident, it is the wide diffusion, in some countries, of smart metering technologies for monitoring of customer electrical consumption. The proven benefits of this technology suggested to the Italian regulative agency the...
This paper deals with time synchronization of devices attached to a smart grid, whose accuracy tightly depends on the accurate estimation of the Time of Arrival (ToA) of the synchronization related messages sent over the power line communication systems. Usually smart grids are quite complex “systems of heterogeneous systems”: the aim of this paper is to suggest a ToA detection mechanism that can...
