A new method for analyzing frequency and voltage fluctuations of power system with wind generators installed

This paper proposes a new method for evaluating characteristics of frequency and voltage fluctuations of power system in which wind generators are installed. In this paper, a new method based on the transfer function models for frequency response and voltage responses of the power system is developed, from which voltage response of each node in the power system as well as the frequency response can be obtained easily and quickly. Its accuracy is investigated by comparing the results between the proposed method and PSCAD/EMTDC simulations.
