Handling current-magnitude measurement in transmission and distribution system state estimator

A framework for handling current magnitude measurements for both transmissi on and distribution system state estimation is given. A fast-decoupled form ulation is developed to enhance both computation time and storage requireme nt. This method is based on the equivalent current measurements, the rectan gular co-ordinates and the weighted least square approach. Tests have shown that the proposed method can outperform other formulations in handling the current magnitude measurements.
