Abstract
Primary frequency control using smart loads with
reactive only compensation (SLQ) has been shown in the past.
In this paper, further improvement in frequency regulation is
shown using smart loads with a back-to-back converter (SLBC)
arrangement. This introduces additional flexibility and thereby,
allows independent and wider control over active and reactive
power consumption of the smart load. The improvement in
frequency regulation with SLBCs is compared against SLQs
through two separate case studies on 4-generator, 2-area test
system and also the 39-bus New-England test system. A future
scenario with reduced system inertia is considered for both case
studies. Unlike previous exercises involving smart loads, in this
study a detailed representation is used for both the multi-machine
transmission system and the distribution networks down to the
medium voltage (MV) level where the smart loads (SLBC/SLQ)
are connected. This avoids the inaccuracies associated with load
aggregation or use of system equivalents wherein the network
constraints, spatial voltage variations etc. are not captured
properly.
