PG&E/EPRI
Protection
and Control
Workshop
The Electric Power Research
Institute (EPRI) is forming a
research program specifically aimed
at improving the understanding of
protection and control issues, as
well as development and testing of
new methods that result in optimal
power system protection for the
21st Century. To ensure that this
research program is responsive
to industry needs, Pacific Gas
& Electric hosted a workshop
in San Francisco, organized by
Vahid Madani in cooperation
with Pei Zhang (EPRI) in order to
gather information and facilitate
a discussion between industry

experts from North and South
America, Europe and Asia. The
ultimate goal of this effort is to
reduce research and development
costs by collaboratively developing
solutions to protection and
coordination challenges.
Participation in this process at an
early stage will enable stakeholders
to shape the direction of this
critical program and maximize
benefits from the fruits of the
program.
The workshop included multiple
presentations by experts from
different countries addressing

of large phasor measurements
systems for adaptive system
protection and improvements
in system visibility, stability and
analysis. The new IEEE C37.118
and IEC 61850 standards and
their impact on the field were also
discussed. The experts shared their
experience from projects in Brazil,
Italy, Japan, Mexico and the United
States.
Participants in the workshop
discussed out-of-step conditions
detection, verification of system
models, dynamic state estimation
and dynamic stability related
simulation.
