Abstract :
This paper presents an efficient data structure management technique to improve the computational process of the power system state estimation (PSSE). The paper also presents a new formulation for the exact decoupled rectangular coordinates PSSE, which makes faster state estimation possible. The performances of these techniques are evaluated using several power system networks including IEEE 14 and 30-bus systems.
