Abstract
This new state estimation method provides the same results as traditional iterative methods when given accurate measurements, and the method does not require an initial guess or have issues with solution convergence. The method has been programmed using MATLAB and has been tested on system of up to over 1400 buses. The computation speed of the new method is found to be competitive with the classical iterative weighted least-squares state estimation method, especially when parallel processing/multi-threading techniques are used. Synchronized phasor measurements can also be incorporated to speed up the solution time.
