TY  - JOUR
AB  - This paper presents a method for processing real-timedata error in generalized state estimation (GSE). Attention is focusedon the two main types of error: network topology errorsand bad data on analog measurements. The proposed approach isable to handle both errors without making any previous assumptionregarding the nature of those errors. The degrading effectsof topology errors over bad data processing when both topologyand measurement errors occur at the same time are evaluated andnew strategy is proposed to overcome it. GSE is treated as a constrainedoptimization problem where measurements and circuitbreakerstatus are modeled as equality constraints.Geometric testsbased on the geometric interpretation of the Lagrange multipliervector are then utilized to determine the source of the error. Theproposed strategy is tested on two model power networks representedat the bus-section level which is derived from the IEEE30-bus and 118-bus systems.
