摘要
采用最小绝对值状态估计算法辨识网络拓扑错误。在传统的最小二乘法状态估计模型中引进扩展变量和量测量,构成最小绝对值状态估计问题,进而转化为线性规划的标准形式求解。在一实际测验系统上进行了试算。
The least absolute value state estimation algorithm is employed in this paper to identify the network topology errors. Extended variables and measurements are introduced into the conventional state estimation model of least square method, which composes a least absolute value state estimation problem. Correspondingly, the problem can be solved through the linear programming model. The proposed least absolute value state estimation algorithm is tested on an actual testing system.
