  • Abstract This thesis proposes a series of methods for analyzing load variations and uses the measured data from substations as an analytic case. It expects to obtain the characteristics of load variations during different time periods, which is taken as base to establish the index of frequency regulation costs allocation. Firstly, moving average method is applied to get the load trend and analyze load variation quantity; simultaneously the load characteristics of each substation during every time period are determined. Subsequently the frequent degree of load variation effect is separated by using the autocorrelation function later and autocorrelation values are transferred to the frequency spectrum via Discrete Fourier Transform. And the frequency spectrum is revised by a high pass filter. It can get the load variation frequency factor with analysis and apply it to costs allocation.
    This thesis would also prove the effect of frequency regulation costs allocation caused by the load variation frequency, based on the comparison between considering the effect of load variation frequency and not considering it. The considerable factors for frequency regulation costs allocation should include the effects of the load variation quantity and load variation frequency so that they can be more reasonably applied to frequency regulation costs allocation.
