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.
