摘　　要：针对假数据攻击行为的定位准确度较低,影响智能电网稳定运行能力的问题,提出基于GCL算法的智能电网假数据攻击定位方法。根据偏差系数求解结果,根据假数据的透明度水平定义CL算法模型;计算电网假数据样本的先验阈值指标,构建假数据攻击行为定位模型;按照电网区域划分原则,分析假数据攻击行为的隐蔽性,判定电网假数据隐蔽性攻击行为能力强度;计算假数据样本的识别特征,完善自适应定位标准,判断已存储数据参量,实现基于GCL算法的假数据攻击定位方法的设计。实验结果表明,该定位方法找到母线扰动事件中的假数据分别在位置S1、S2、S3、S4、S5,线路扰动事件当中的假数据分别在位置S6、S7,定位结果与实际情况一致,准确度较高,可以为电网运行提供技术支持。Aiming at the problem that the location accuracy of false data attacks is low and affects the stable operation ability of smart grid,this paper proposes a location method for false data attacks in smart grid based on GCL algorithm.According to the result of deviation coefficient,CL algorithm model is defined according to the transparency level of false data.The prior threshold index of false data samples is calculated,and the false data attack behavior location model is constructed;According to the principle of power grid regional division,the concealment of false data attack is analyzed,and the capability strength of power grid false data concealment attack is determined;Calculate the identification characteristics of false data samples,improve the adaptive positioning standard,judge the stored data parameters,and realize the design of false data attack positioning method based on GCL algorithm.Experimental results show that the location method finds that the false data in bus disturbance events are located at S1,S2,S3,S4 and S5 respectively,and the false data in line disturbance events are located at S6 and S7 respectively.The positioning result is consistent with the actual situation,with high accuracy,which can provide technical support for power grid operation.
