The security of smart grid is affected by the quality of power big data.In order to improve the security of power grid,the vulnerability location of smart grid is located through power big data.The two-dimensional wavelet threshold denoising method is used to filter the noise data in smart grid power big data,remove the redundant data in power grid power data,and complete the quality optimization of power big data.Data mining technology is applied to build the model of smart grid security vulnerability mining,and the model of big data and vulnerability mining is used to locate the security vulnerability of smart grid.The experimental results show that the proposed method can achieve high-precision location of big data vulnerability in smart grid,and has positive significance for the security protection of big data in smart grid.
