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...
PLC is the acronym for ??PowerLine Communication?? and means data communications via power wiring. PLC was initially used for tele-protection and tele-monitoring of electrical substations by means of high voltage power lines, in order to avoid costs of microwave or fiber optic links. More recently, PLC has been also adopted for automatic smart metering. However, only with the advent of low-cost digital...
This paper deals with the application of the Chirp Spread Spectrum (CSS) modulation for the synchronization of wireless sensors. Chirp modulation is a well known technique for precise localization, originally developed for RADAR applications. When CSS is used for communication purposes, radio frequency pulses are modulated in order to convey also user data. This approach allows for robustness, thanks...
WirelessHART (WH) is a recently standardized wireless fieldbus. The connection between WH and the host plant network is obtained with Access Points and Gateways. These devices have complex (and costly) architecture, but do not offer flexibility with respect to new update of the specification, and have limited diagnostic capabilities. In this paper, the architecture of a smart WH Access Point, which...
