摘要
En 中文
A highly-linear branch-current-based state estimation model for distribution system is proposed in this paper. This algorithm is based on the concepts presented in Baran and Kelley (1995), Baran and Kelley (1995) proposed a novel branch-current-based approach to solve distribution state estimation. However, the treatment of current magnitude measurements and the complicated gain matrix in Baran and Kelley (1995) greatly degrade its value in real-world applications, The approach presented in this paper substantially revised the original method. A new algorithm with constant gain matrix and a decoupled form was developed, Tests have shown that the proposed method is robust, efficient and needs minimal storage requirement. The new algorithm provides a very good theoretical foundation for developing more applications and researches in this area.
