Performance Analysis of Discrete Wavelet Multitone Transceiver for Narrowband PLC in Smart Grid
Smart Grid is an abstract idea, which involves the utilization of powerlines for sensing, measurement, control and communication for efficient utilization and distribution of energy, as well as automation of meter reading, load management and capillary control of Green Energy resources connected to the grid. Powerline Communication (PLC) has assumed a new role in the Smart Grid scenario, adopting the narrowband PLC (NB-PLC) for a low cost and low data rate communication for applications such as, automatic meter reading, dynamic management of load, etc. In this paper, we have proposed and simulated a discrete wavelet multitone (DWMT) transceiver in the presence of impulse noise for the NB-PLC channel applications in Smart Grid. The simulation results show that a DWMT transceiver outperforms a DFT-DMT with reference to the bit error rate (BER) performance
State-of-the-art in Power Line Communications: from the Applications to the Medium
In recent decades, power line communication has attracted considerable
attention from the research community and industry, as well as from regulatory
and standardization bodies. In this article we provide an overview of both
narrowband and broadband systems, covering potential applications, regulatory
and standardization efforts and recent research advancements in channel
characterization, physical layer performance, medium access and higher layer
specifications and evaluations. We also identify areas of current and further
study that will enable the continued success of power line communication
technology.Comment: 19 pages, 12 figures. Accepted for publication, IEEE Journal on

Upgrading the Power Grid Functionalities with Broadband Power Line Communications: Basis, Applications, Current Trends and Challenges
This article reviews the basis and the main aspects of the recent evolution of Broadband Power Line Communications (BB-PLC or, more commonly, BPL) technologies. The article starts describing the organizations and alliances involved in the development and evolution of BPL systems, as well as the standardization institutions working on PLC technologies. Then, a short description of the technical foundation of the recent proposed technologies and a comparison of the main specifications are presented; the regulatory activities related to the limits of emissions and immunity are also addressed. Finally, some representative applications of BPL and some selected use cases enabled by these technologies are summarized, together with the main challenges to be faced.This work was financially supported in part by the Basque Government under the grants IT1426-22, PRE_2021_1_0006, and PRE_2021_1_0051, and by the Spanish Government under the grants PID2021-124706OB-I00 and RTI2018-099162-B-I00 (MCIU/AEI/FEDER, UE, funded by MCIN/AEI/10.13039/501100011033 and by “ERDF A way of making Europe”)

Electric Vehicles Charging Control based on Future Internet Generic Enablers
In this paper a rationale for the deployment of Future Internet based
applications in the field of Electric Vehicles (EVs) smart charging is
presented. The focus is on the Connected Device Interface (CDI) Generic Enabler
(GE) and the Network Information and Controller (NetIC) GE, which are
recognized to have a potential impact on the charging control problem and the
configuration of communications networks within reconfigurable clusters of
charging points. The CDI GE can be used for capturing the driver feedback in
terms of Quality of Experience (QoE) in those situations where the charging
power is abruptly limited as a consequence of short term grid needs, like the
shedding action asked by the Transmission System Operator to the Distribution
System Operator aimed at clearing networks contingencies due to the loss of a
transmission line or large wind power fluctuations. The NetIC GE can be used
when a master Electric Vehicle Supply Equipment (EVSE) hosts the Load Area
Controller, responsible for managing simultaneous charging sessions within a
given Load Area (LA); the reconfiguration of distribution grid topology results
in shift of EVSEs among LAs, then reallocation of slave EVSEs is needed.
Involved actors, equipment, communications and processes are identified through
the standardized framework provided by the Smart Grid Architecture Model
(SGAM).Comment: To appear in IEEE International Electric Vehicle Conference (IEEE

Equipment management trial : final report
Executive Summary
The Equipment Management (EM) trial was one of the practical initiatives conceived and
implemented by members of The Application Home Initiative (TAHI) to demonstrate the
feasibility of interoperability between white and brown goods, and other domestic equipment.
The trial ran from October 2002 to June 2005, over which period it achieved its core
objectives through the deployment in early 2005 of an integrated system in trials in 15
occupied homes. Prior to roll out into the field, the work was underpinned by soak testing,
validation, laboratory experiments, case studies, user questionnaires, simulations and other
research, conducted in a single demonstration home in Loughborough, as well as in
Universities in the East Midlands and Scotland.
Throughout its life, the trial faced significant membership changes, which had a far greater
impact than the technical issues that were tackled. Two blue chip companies withdrew at the
point of signing the collaborative agreement; another made a major change in strategic
direction half way through and withdrew the major portion of its backing; another corporate left
at this point, a second one later; one corporate was a late entrant; the technical leader made
a boardroom decision not to do the engineering work that it had promised; one company went
into liquidation; another went up for sale whilst others reorganised. The trial was conducted
against this backdrop of continual commercial change. Despite this difficult operating
environment, the trial met its objectives, although not entirely as envisaged initially – a tribute
to the determination of the trial’s membership, the strength of its formal governance and
management processes, and especially, the financial support of the dti.
The equipment on trial featured a central heating/hot water boiler, washing machine, security
system, gas alarm and utility meters, all connected to a home gateway, integrated functionally
and presented to the users via a single interface.
The trial met its principal objective to show that by connecting appliances to each other and to
a support system, benefits in remote condition monitoring, maintenance, appliance & home
controls optimisation and convenience to the customer & service supplier could be provided.
This is one of two main reports that form the trial output (the other, the Multi Home Trial
Report, is available to EM Trial members only as it contains commercially sensitive
information). A supporting library of documents is also available and is held in the virtual
office hosted by Loughborough University Centre for the Integrated Home Environment
