Abstract :
Power system stability analysis is extremely complex due to its multi-time scale nature, high dimensionality and non-linearity. For improving the efficiency of power system analysis, it is necessary to study multi-time scale dynamic models of power systems and relevant model reduction. In this paper, a singular perturbation model incorporating fast and slow dynamics is derived based on component equations of power systems. The systematically reduction method of power system is introduced to obtain reduced model of power system, and the simplified power system model obtained by neglecting fast dynamics and fixing slow dynamics corresponds to traditional power system model reserving structure
