A general and novel approach for the development of the linearized model for the dynamic stability analysis of multimachine power systems including HVDC links is presented in this paper. The modelling considers detailed representation of the generators and DC links with their associated controllers and nonlinear voltage dependent loads. The component models are formulated separately and are interconnected by the network model which is directly obtained from the load flow studies using Newton' s method. An example of a 3-machine power system is considered to illustrate the analysis presented in the paper.
