Abstract

This paper presents the idea of a partitioned linear state estimator (PLSE) as an alternative to the classical linear state estimator (LSE). PLSE is found to be especially useful for performing state estimation in large systems comprising of multiple entities. The best example of this is different utilities functioning under an independent system operator (ISO). The proposed technique is immune to the number of tie-lines that exist between the utilities as well as the number of utilities that are present under the ISO. Its biggest advantage is that it reduces discrepancies occurring at the boundaries while requiring minimum exchange of information between the utilities. The IEEE-14 bus system is used as the test system for presenting the idea. The results indicate that PLSE is a robust method for performing state estimation in big systems.
