摘　　要：相对于输电网状态估计,配网状态估计中存在的最大问题就是量测不足。为了最大化利用配网同步相量量测(D-PMU)数据和高级计量体系(AMI)数据,研究了这两种数据的处理方法。通过对D-PMU电流相量的处理,解决雅克比矩阵病态构造的问题。通过"伪D-PMU数据"的计算,增加了量测冗余度,提高了算法抗虚假数据攻击的能力,并对其进行了严格的数学论证。对于AMI数据,基于谐波分量分解方法对低压节点负荷进行超短期预测,得到了同一时间断面注入功率数据。IEEE 123节点标准算例仿真结果表明,所提方法可以较好地预测超短期负荷数据,有效抵御虚假数据注入攻击,状态估计的准确性和一致性得到了提高。The biggest problem in distribution network state estimation,compared to transmission network state estimation,is insufficient measurement.In order to maximally make use of distribution network synchronous phasor measurement(D-PMU)data and advanced metering system(AMI)data,this paper studies the two data processing methods.Through the treatment of D-PMU current phasor,the problem of Jacobi ill-conditioned structure is solved.Through the calculation of"pseudo-D-PMU data",the redundancy of measurement is increased,and the ability of the algorithm to resist the attack of pseudo data is improved.IEEE 123 bus standard example simulation results show that the proposed method can be adopted to better predict ultra-short-term load data;compared with the traditional least square algorithm,the proposed method can be adopted to effectively resist the attack of false data injection,and the accuracy and consistency of state estimation are improved.
