Abstract: In order to reduce the error of voltage fluctuation tracking and shorten the tracking time, a high proportion new energy medium voltage power grid voltage fluctuation tracking method based on a double layer master slave game is proposed. Firstly, construct a two-layer master-slave game model, analyse the voltage regulation strategy of the high proportion new energy grid using the utility function, and collect operational data of the new energy grid. Secondly, wavelet transform is used to analyse the sudden changes in voltage signals and identify the sources of voltage fluctuations in the medium voltage power grid. Finally, the Hilbert Huang transform is used to decompose the voltage fluctuation source signal, obtain the instantaneous fluctuation frequency of the power grid voltage and complete the tracking of voltage fluctuations. The results show that the voltage fluctuation tracking error of the proposed method is significantly reduced, with a maximum error of only 1.3 V.

Keywords: double layer master slave game; high proportion; new energy grid; voltage fluctuation tracking; medium voltage distribution network.
