This general framework of LCNC and RSOC linked to
physical model of the power system/communication network
is generalized to allow for modeling of a wide range of smart
grid devices and controls. The next sections discuss the power
system, communication network, and control components in
more detail.
A. Power System Network Components
The power system network, which consists of an
interconnection of transmission lines and transformers, is
modeled by an interconnection of impedances modeling each
component. Network equations in terms of the nodal
admittance can be written for an n bus system from this as
follows [12]:
