Comprehensive Assessment of Electric Drive Vehicles; Smart Grid
Security and Wireless Network Reliability
– : To convert
a critical mass of drivers to electric vehicle (EVs, we must first drive
market penetration by establishing policies to reduce ownership cost of
(EVs and plug-in hybrid electric vehicles (PHEVs. This is according to an
update on the challenges to Smart Grid in a new issue of Proceedings of the
IEEE. Electric vehicles (EVs, essential to Smart Grid’s future, are
considered one of the most promising ways to reduce fossil fuel
dependence.
This Smart Grid special issue, «The Electric Energy System of the
Future,» published in the Proceedings of the IEEE which is the world’s most
highly-cited general-interest journal in electrical engineering and
computer science since 1913, is one of the most comprehensive assessments
of this topic to date.
According to authors of this 13-article report, there is still a lot to
be accomplished in three dominant areas: governmental policies at both
federal and state levels, customer efficiency needs and new intelligent
computer software and hardware technologies.
In an article on (EVs, «Vehicle Electrification: Status and Issues,»
the authors concede while automakers recognize that electric vehicles are
critical to the future of the industry, widespread consumer adoption of EVs
is inhibited not only by actual costs but perception of costs.
Other EV issues which need to be addressed include best practices for
extraction and mining of rare earths and lithium; development and
deployment of EV technologies; standardization of industry protocols of
plugs and chargers; deployment of charging infrastructure; public education
and national and global political will for the adoption of smart grid
technology and renewable energy sources.
One of the most important challenges in Smart Grid is providing reliable
last mile network communication, according to the paper «Multigate
Communication Network for Smart Grid» by , Fellow IEEE and Bin Hu, Member IEEE. The paper describes
various techniques such as multigate, multi channel routing as well as a
packet scheduling technique to enhance the network performance in terms of
reliability, latency and throughput. According to the authors, «The results
indicate that a combination of multipath routing and the backpressure-based
packet-scheduling scheme can show a significant improvement in the network
reliability, latency, and throughput performance.»
Cyber security of the Smart Grid is another major priority. In the
article by , National
Coordinator for Smart Grid Interoperability at the National Institute of
Standards and Technology (NIST, it is noted that «If Smart Grid is to
become the electric system of the future, we must deal today with the
challenges it faces in terms of reliability and security in both
wired and wireless communication environments.»
In «High Assurance Smart Grid: A Three-Part Model For Smart Grid Control
Systems,» the authors admit that there is no single solution to Smart Grid
Cyber-security. «Rather, it’s only through a combined approach can grid
control systems be sufficiently engineered. «
According to the authors, the electric service reliability that defines
a multi-level framework and for architecture to be used throughout the
electrical system, a High-Assurance Smart Grid architecture that is both an
architectural approach and an aspirational goal is required.
