IEEE Power & Energy Magazine - July/August 2021 - 6

find flexibility? Elsewhere, or " closer
to home " ? This issue mainly focuses on
finding in-house flexibility via creative
demand-side management, storage
utilization, effective operation algorithms
(encompassing both transmission
and distribution networks), and others.
Describing several starting, ongoing, and
recently completed projects, the articles
in this issue illustrate how to get in-house
flexibility within a power system.
The mostly in-house flexibility
sources considered in this issue include
the following:
✔ using adaptive optimal control
techniques to derive dynamic
operation limits (involving both
transmission and distribution
networks) to gain flexibility
✔ leveraging the interrelations among
electric power, natural gas, and
heat systems to enlist flexibility
from multiple energy systems
✔ without significantly altering
the routines of the owners of
electrical vehicles, creating flexibility
out of the batteries of these
electrical vehicles
✔ coordinating the use of different
storage facilities at various
locations to create flexibility via
cloud computing
✔ in jurisdictions with high levels of
both solar and wind power, coordinating
different demand-side management
interventions to counteract
the pernicious effects of steep ramps
at the beginning and end of the day
✔ using demand-side management
and storage to create the flexibility
required to delay infrastructure
reinforcement.
Mark McGranaghan complements
the feature articles with his " In My
View " column that reviews different
flexibility instruments while providing
historical insight.
Enlisting in-house flexibility constitutes
a most valuable endeavor that
will contribute to the increasing, but
smooth, integration of weather-dependent
renewable sources in power systems.
This will ultimately result in decarbonizing
these systems.
Leader's Corner
IEEE Power & Energy Society (PES)
Secretary Jonathan Sykes provides his
insights regarding the challenges the
industry and our Society have endured
through the pandemic and how we
are growing from the experience. He
touches on many of the characteristics
that exhibit the resilience of PES and its
members to meet these challenges as we
embrace greater transparency and diversity
in our processes and leadership.
History
This issue's " History " column explores
the subject of short circuit protection.
Author Robert D. Barnett rejoins our
pages to bring us a treatment of the
challenges of fault protection in the
early years of electrification. Beginning
in the 1890s and taking us up
to the 1920s, this article covers early
protection devices, including fuses,
