Power System Static-State Estimation, Part I: Exact Model

TLDR

The static state of a power system is the vector of bus voltage magnitudes and angles, and its estimation involves processing redundant meter data through iterative techniques while addressing modeling errors and interconnection issues. Initial computer simulations demonstrate the feasibility of the proposed static‑state estimation approach.

Abstract

The static state of an electric power system is defined as the vector of the voltage magnitudes and angles at all network buses. The static-state estimator is a data processing algorithm far converting redundant meter readings and other available information into an estimate of the static-state vector. Discussions center on the general nature of the problem, mathematical modeling, an interative technique for calculating the state estimate, and concepts underlying the detection and identification of modeling errors. Problems of interconnected systems are considered. Results of some initial computer simulation tests are discussed.
