Computer simulation and analysis of power systems
are necessary for both planning and operation. These analyses
require an appropriate mathematical model of the power system
that includes many inter-related linear/nonlinear differential
and algebraic equations. Such mathematical model is also
needed for the design of an appropriate control system. In this
paper, the comprehensive dynamic model of power systems
including dynamic voltage restorer (DVR) is presented. In this
procedure, the individual components of a power system are
modeled using appropriate frame of references. Then all related
equations are transformed to a common network frame of
reference and tied to each other through the Y-matrix of the
transmission network. The validity of the proposed dynamic
model is verified by the simulation results of a five-bus system
using Matlab Simulink software.
