Engineering Research Initiation Grant: A New Approach to Obtaining a Robust Power System State Estimator

该项目涉及一种预估程序的研究，以修改电网方程的结构，使线性规划(LP)型状态估计器一致地拒绝现有的粗差。示出了旋转变换(通过单变量示例)以期望的方式重构估计方程，使得变换坐标中的LP估计器拒绝先前接受的坏数据。我们将研究将这种方法扩展到多变量情况的可行性和实用性。确定了要完成的问题领域和相关任务。拟议工作的结果将与普通LP估计器进行比较测试。将为此目的开发和记录计算机程序。

This project involves the investigation of a pre-estimation procedure to modify the structure of the power network equation so that a linear programming (LP) type state estimator will consistently reject the existing gross errors. A rotational transformation is shown (by way of a single variable example) to restructure the estimation equations in the desired manner such that an LP estimator in the transformed coordinates rejects the previously accepted bad data. The feasibility and practicality of an extension of this approach to the multivariate case will be studied. The problem areas and the associated tasks to be accomplished are identified. The results of the proposed work will be comparatively tested against the plain LP estimator. A computer program will be developed and documented for this purpose.
