[en] The degree of market power (more precisely, the
potential for market power obtained from a market
concentration indicator such as HHI) increases as
system stress increases. This paper illustrates the effect
of system loading on the reactive power HHI for various
locations. The paper also illustrates the use of
sensitivity formulas to come up with measures intended
to improve (reduce) the overall HHI of a system by
judicious addition of reactive power resources. Better
results in terms of reduction of market concentration as
a result of reactive power are obtained when the voltage
collapse characteristics of the system are considered.
The concepts are illustrated using the 14-bus and 57
IEEE-test systems.
