Forced Oscillation Source Location in Power Systems Using Multivariate Synchrosqueezing Transform
This paper proposes a multivariate synchrosqueezing transform(MS ST)based power system forced oscillation source location(FOSL)method to locate the forced oscillation source using measurement responses.The method uses the measurement responses to form the multi-channel measurement matrix of each generator,and the MS ST is employed to decompose the multi-channel measurement matrix to obtain the MSST coefficient matrix.Further,the MSST coefficient matrix associated with the forced oscillation mode is determined by using the proposed energy weight.Using the determined MSST coefficient matrix associated with the forced oscillation mode,the MSST-based forced oscillation dissipation energy of each generator is calculated and the forced oscillation source can be located via the proposed FOSL criterion.The performance of the proposed MSST-based FOSL method is evaluated by the simulation data of WECC 179-bus test system and the field-measurement PMU data of Liaoning power grid,and the results validate the accuracy and efficiency of the proposed method in FOSL.
