N2 - This paper presents an approach to evaluate the smoothing effect of wind power generators on power system operation based on actual wind output data in Tohoku area in Japan. Conventional LFC (Load Frequency Control) model is used and the effect of the smoothing effect on frequency control is evaluated. For evaluating the smoothing effect, spectral analysis and integration of each frequency of wind outputs are utilized. In this study, the smoothing effect in multi areas is evaluated and the decrease of the power spectrum density of individual wind generator is confirmed by comparing with the density of integrated wind generators in wide areas. Moreover, we assume many wind generators are connected to power systems, and analyze the smoothing effect of integrating wind power generators on power system operation. By using this multi-generator model, the influence of generator integration on the LFC is evaluated by investigating the change of frequency deviations. In addition, a method to suppress the frequency deviation caused by wind power fluctuations is proposed with control of batteries equipped in Electric Vehicles (EVs)’ in the power system model consists of wind generators and EVs.
