A review of negative sequence current
John Wang,Randy Hamilton +1 more
TL;DR: In this paper, the rotation direction of the negative sequence current was clarified to avoid potential confusion in synchrophasor metering, and the authors also explained that all sequence components rotate in the same direction.

Newton-Raphson State Estimation Solution Employing Systematically Constructed Jacobian Matrix
TL;DR: In this article, elements of the state estimation Jacobian matrix are obtained considering the power flow measurements in the network elements, these elements are processed one-by-one and the Jacobian Matrix H is updated suitably in a simple manner.
