Abstract
It is expected that in the future, customers will play a much more active role in modern power distribution
systems. Instead of being passive agents, customers will be encouraged to participate in many other
functions, such as frequency and voltage control, by providing a rapid, active, and reactive power reserve
for peak load management through price responsive methods and also as energy providers through
embedded generation technologies. This article introduces a new technology, called demand as voltagecontrolled
reserve, which can help mitigation of momentary voltage sags. The technology can be provided
by thermostatically controlled loads as well as other types of load. This technology has proven to be
effective in distribution systems with a large composition of induction motors, when voltage sags present
slow recovery characteristics because of the deceleration of the motors during faults. This article presents
detailed models, discussion, and simulation tests to demonstrate the technical viability and effectiveness of
the demand as voltage-controlled reserve technology for mitigating voltage sags.
