net-load peaks to net valleys can smooth
variations in load profiles. when the
heating devices have suitable controllability, they can also be valuable sources
of reserves that mitigate forecast errors
and faults. the article examines the pros
and cons of thermal-electricity integration and lays out generic principles and
characteristics related to thermal sector
flexibility as well as demonstrates its possibilities with specific examples.
A major potential for flexibility in the
heat sector is created by the low cost of
storing heat, which provides an opportunity to shift electricity demand. Another
option is to utilize hybrid systems where
either electricity or fuel can be used to
produce heat depending on the price
variations of either option. this category
includes many different options, starting
from dual heaters in buildings all the way
to large district heating systems with cHp
plants, fuel boilers, and electric heaters. in
addition, the article examines flexibility

created by thermal loads in several countries around the world.
in "the triple Bottom line for Efficiency," authors casey et al., examine the
energy-water nexus and address efficiency financial, environmental, and social
impacts. the article looks at examples
that demonstrate the emerging integration
of the water network and energy grids,
particularly where water is used in the
power production, wastewater treatment,
and the end-use part of the electric grid.
water presents a variety of challenges for
the electric sector including the reduction
of water use in power plants, and using
efficient electric technologies for water
treatment, transport, desalination, industrial processes, and end uses can conserve
electricity, hence reducing water use in
power plants. water and wastewater treatment facilities are good candidates for
demand response because they are energy
intensive and have significant flexibility
through variable speed pumps and inher-

ent storage in water tanks. this operational flexibility can make these facilities
ideal partners for electric utilities seeking
to manage electric load through demandresponse programs.
"Unlocking Flexibility" by Dall'Anese
et al., examines integrated operational solutions that strike a balance among cost,
reliability, and environment while accounting for the affordability of energy,
sustainability, and social acceptability.
this article gives an overview of possible
joint control and optimization approaches
for multienergy systems. it also discusses the core challenges related to the
development of distributed control and
optimization algorithms that allow different parties to retain controllability of
their own energy assets while maintaining their individual performance and reliability objectives. the physical couplings
among systems is represented in mathematical terms through the so-called energy hub
approach that offers the flexibility to
