TLDR
In this paper, a new technique for voltage sag state estimation is presented, based on estimating the number of voltage sags occurring at non-monitored buses from the number recorded at a limited number of monitored buses.Abstract:
This paper presents a new technique for voltage sag state estimation. The proposed method is based on estimating the number of voltage sags occurring at nonmonitored buses from the number of sags recorded at a limited number of monitored buses. This problem, contrary to the traditional state estimation where redundant measurements are available, is formulated as an underdetermined system of equations. In this paper, linear integer programming techniques are employed to solve this estimation problem. The performance of the proposed method is tested by means of several case studies applied in the IEEE 24-bus reliability test system (RTS) and in the IEEE 118-bus test system.read more
