The Fundamental Concept of Unified Generalized Model and Data Representation for New Applications in the Future Grid Conference Paper uri icon


  • The concept of interoperability of data and model as presented in this paper is viewed as being very useful for implementing variety of future applications related to power system monitoring, protection, control and operation. To illustrate the proposed concept, two applications are used: state estimation and fault location. Generalized State Estimators (GSEs) consider both measurements and switching device statuses as variables to be estimated. We propose a unified generalized state estimator that uses only one class of network objects (node-breaker), which would avoid model conversions, enables unified topology processing, and supports flexible forms of generalized estimation. The proposed Fault Location (FL) application uses different types of measured data which utilizes power system static data modeled using bus-branch. Significant number of mappings is required to correlate the measured data and model. It is shown that both applications will be simplified if unified generalized representation of data and model as suggested in this paper is utilized. 2012 IEEE.
