an invaluable resource for addressing the myriad critical
technical engineering considerations in modern electric power
system design and operation Power SyStem
B
Power System Monitoring and Control (PSMC) is becoming increasingly significant in the e
v
r
design, planning, and operation of modern electric power systems. In response to the a
n monitoring
existing challenge of integrating advanced metering, computation, communication, and i •
w
control into appropriate levels of PSMC, Power System Monitoring and Control presents a
a
comprehensive overview of the basic principles and key technologies for the monitoring, ta
n and Control
protection, and control of contemporary wide-area power systems. A variety of topical a
b
e
issues are addressed, including renewable energy sources, smart grids, wide area stabilizing, •
coordinated voltage regulation and angle oscillation damping—as well as the advantages m
it
of phasor measurement units (PMUs) and global positioning system (GPS) time signal. a
n
i
Analysis and synthesis examples, along with case studies, add depth and clarity to all topics. Hassan Bevrani • Masayuki Watanabe • Yasunori Mitani
• Provides an up-to-date and comprehensive reference for researchers and P
engineers working on wide-area PSMC o
w
• Links fundamental concepts of PSMC, advanced metering and control theory/
e
techniques, and practical engineering considerations r

• Covers PSMC problem understanding, design, practical aspects, and topics such S
y
as smart grid and coordinated angle oscillation damping and voltage regulation
s
t
• Incorporates the authors’ experiences teaching and researching in international
e
locales including Japan, Singapore, Malaysia, and Australia m

Power System Monitoring and Control is ideally suited for a graduate course on this topic. It m
is also a practical reference for researchers and professional engineers working in power
o
system monitoring, dynamic stability and control. n
