 للكاتب . A. E. Mansour Electrical Engineering Department, Faculty Of Engineering, Al-Azhar University ABSTRACT This paper presents, for large-scale power systems, a distributed bad-data pre-cleaning (BDPC)technique with subsequent hierarchical recursive static state estimation (RSSE) method when the meter placement used is optimal. The optimality here means that the meter configuration does satisfy the necessary and sufficient conditions for the detection …

 للكاتب : Ahmed E. Mansour Electrical Engineering Department, Faculty of Engineering , University of AL-Azhar ABSTRACT In this paper, applications of an optimal meter configuration system,(introduced in previous work for the author), on the different electric networks (AEP 14-bus system, AEP 30-bus system, and 34-bus network) will be presented. The meter configurations must satisfy the necessary and sufficient conditions for …
