New Formulation for Distribution System State Estimation
2012 VI Andean Region International Conference, 2012This paper presents a new formulation for system state estimation of passive electric distribution networks. The fundamental idea discussed here is how to obtain the state of the system at maximum demand condition using three sources of information: 1) a quasi-symmetric matrix called TRX representing network structure and topology, 2) power ...

Branch Current based Distribution System State Estimation
2019 International Conference on Electrical, Electronics and Computer Engineering (UPCON), 2019For last some decades there has been significant changes in distribution systems. These changes have a substantial impact on the system configuration thereby creating new opportunities of monitoring. In particular, the smart grids, perhaps the next stage of the distribution systems. Such developments need a comprehensive knowledge of the system.

Load pseudomeasurements in distribution system state estimation
2015 IEEE Eindhoven PowerTech, 2015Distribution system state estimation (DSSE) is an essential tool in active distribution grids in order to enhance the awareness of the power system operators regarding the state of the distribution system. One of the peculiarities of the DSSE is the lack of adequate real-time measurements.

Distribution system state estimation using semidefinite programming
2015 North American Power Symposium (NAPS), 2015Growing penetration of distributed energy resources connected to power distribution networks requires accurate, robust, and dependable real-time system monitoring tools. This paper considers the state estimation (SE) problem in distribution systems and proposes a new convex relaxation based approach to solve it as a semidefinite programming problem ...

An improved state estimator in distribution systems
2011 IEEE International Conference on Computer Science and Automation Engineering, 2011An improved state estimation algorithm based on branch current is put forward to revise leverage-point measurements with gross errors in distribution systems. Using the inherent characteristic of leverage-point measurement, this method introduces structure robust factors into the objective function of the weighted least absolute value (WLAV) estimator ...
