Topology error identification using branch current state estimation for distribution systems

The branch-current-based state estimation (BCSE) method is a novel approach to solve distribution state estimation (SE). However, without suitable topology error processing for BCSE, the value of the BCSE will be degraded in real world applications. Therefore, this paper introduces a method for topology error identification based on the use of normalized residuals resulting from the employment of the BCSE method. The effectiveness of the proposed approach is demonstrated and in addition, the topology error identification results obtained by using the proposed approach are presented in this paper.
