web, cognitive radio, and cognitive networking serve as attempts to incorporate
intelligence into communication and are
extensions of the active networking concept. the fundamental nature of complexity and communication in the form
of active networking and communication
complexity plays a role in power system
information theory.

Chapter 12
state estimation and stability are fundamental components of control of the power
grid and are also used in communication
systems; both topics are reviewed with particular emphases on application in power
systems. networked control extends control of the power grid over communication
networks and must overcome challenges
that variable performance and reliability of
the communication network impose upon
the control system.

Chapter 13
Phasors, symmetrical components, and
synchrophasors are explained. understanding synchrophasors and their applications allows their communication

and networking requirements to be better
understood and their properties to be exploited to improve communication. compression of synchrophasors, by both passive (classical source coding) and active
(active networking techniques) means,
is also explained. For applications to use
synchrophasors, they must be transported
in a standard manner. thus, synchrophasor standards are reviewed.

Chapter 14
Advances in power electronics will
impact both the smart grid and its supporting communications. Advances in
high-power, solid-state electronics along
with communication will enable the
power grid to operate in a more efficient
and flexible manner. A comprehensive
review of power electronic advances in
FActs and the solid-state transformer
is given. superconducting technology
offers new capability to power grid components that may be leveraged not only
for power system efficiency but also for
new communication and computation
technologies such as quantum computation within the power grid.

Chapter 15
technologies exhibit trends that allow
us to anticipate new innovation far beyond the limited smart grid horizon. core
themes are smaller-scale power generation and management, nanogrids, power
system information theory, wireless power
transmission, the ability to harness power
from geomagnetic storms, and the integration of quantum phenomena with power
grid, including quantum communication,
computation, and energy teleportation.
Power system information theory enables
maxwell's demon within the power grid.
nanoscale communication networks are
discussed for future nanogrids. spacebased power generation is also explored.

Appendix
there is an introduction to the concept of cosimulation and a description
of freely available power system and
communication network simulators.

Advanced 720Mvar SVC Solution
for 750kV Substation in Dunhuang
Duhuang, a fortress of ancient Silk Road, now becomes an
important power transmission hub in western China. Large
amount of renewable energy is transmitted from Dunhuang to
other parts of China to satisfy the increasing electricity
consuming demands.
As a power stability expert, NR Electric is actively involving in
this project. Our 720Mvar SVC solution, including SVC valves,
SVC protection & control system, Controllable Shunt Reactors
(CSRs) and CSR protection & control system, has guaranteed
the reliable and stable operation of renewable energy
grid-connection for almost two years.
