The paper proposes a methodology to model the impulse rate of sporadic impulsive noise, namely the impulsive noise that is generated by the transients during the on/off switching of electrical appliances. In particular, it is proposed to exploit the publicly available datasets of power consumption measurements campaigns to derive the instants when a switching on/off event occurs. The statistics of...
Home energy management systems can be used to monitor and optimize consumption and local production from renewable energy. To assess solutions before their deployment, researchers and designers of those systems demand for energy consumption datasets. In this paper, we present the GREEND dataset, containing detailed power usage information obtained through a measurement campaign in households in Austria...
Households account for a notable amount of overall energy consumption, thus they represent a field where it is possible to potentially obtain great energy savings. Energy management systems (EMSs) can be used to this end. They allow for monitoring and managing energy consumption of household appliances or renewable energy sources, as well as making users aware of their energy consumptions. User awareness...
The paper proposes a cross-platform simulator that allows to realistically simulate G3-PLC systems up to the network layer. The platform consists of two simulators: one for the physical (PHY) layer and one for the data link (DLL)/adaptation (ADP) layer. The former is implemented in MATLAB, while the latter in OMNeT++. To improve the performance and coverage of G3-PLC, a simple adaptive tone mapping...
Households account for a significant fraction of overall energy consumption. Energy usage can be reduced by improving the efficiency of devices and optimizing their use as well as by encouraging people to change their behaviour towards a more sustainable lifestyle. In this study, we investigate patterns of domestic energy use in Carinthia (Austria) and Friuli-Venezia Giulia (Italy). In particular,...
In this paper, we propose enhancements at the medium access control (MAC) sub-layer for the G3-PLC technology. In particular, we develop a convergent network, consisting of different network devices, to easily integrate G3-PLC in Ethernet local area networks (LANs). The proposed network leads to coverage and throughput improvements for in-home/building applications. Furthermore, since the G3-PLC medium...
The concept of the electrical grid conceived as an infrastructure that only delivers power to the end users is going to disappear. In the next years, the electrical grid will be viewed as a smart grid (SG), namely, a distributed complex large scale system that needs to smartly manage flows of electricity produced by big or small plants. To fully exploit the SG potentialities, we think that it is mandatory...
To support the requirements of smart grids (SGs) applications, telecommunication industries and standardization organizations have proposed to use narrow-band (NB) orthogonal frequency division multiplexing (OFDM) based solutions over power line communications (PLCs) networks. Among these solutions, the most important are the PoweRline Intelligent Metering Evolution (PRIME), the ERDF G3-PLC, and the...
We consider the problem of the joint allocation of power and cyclic prefix (CP) duration to maximize the system capacity in orthogonal frequency division multiplexing (OFDM). A closed form solution to the problem does not exist and the exhaustive search of the optimal values is practically unfeasible. Therefore, we propose a sub-optimal iterative power allocation algorithm jointly with the CP adaptation...
We study capacity improvements in WLAN technology that uses orthogonal frequency division multiplexing (OFDM) and, conventionally, time division multiple access (TDMA) to deliver high quality of service (QoS) traffic. We show that improvements are attainable via the adaptation of the cyclic prefix to the channel conditions w.r.t. the baseline system that uses a fixed value of CP. Furthermore, we compare...
