  We analyze the dynamics of a distribution circuit loaded with many induction
motor and subjected to sudden changes in voltage at the beginning of the
circuit. As opposed to earlier work \cite{13DCB}, the motors are disordered,
i.e. the mechanical torque applied to the motors varies in a random manner
along the circuit. In spite of the disorder, many of the qualitative features
of a homogenous circuit persist, e.g. long-range motor-motor interactions
mediated by circuit voltage and electrical power flows result in coexistence of
the spatially-extended and propagating normal and stalled phases. We also
observed a new phenomenon absent in the case without inhomogeneity/disorder.
Specifically, transition front between the normal and stalled phases becomes
somewhat random, even when the front is moving very slowly or is even
stationary. Motors within the blurred domain appears in a normal or stalled
state depending on the local configuration of the disorder. We quantify effects
of the disorder and discuss statistics of distribution dynamics, e.g. the front
position and width, total active/reactive consumption of the feeder and maximum
clearing time.
