The equivalent split-circuit formulation is a novel approach that has\nrecently been applied to a range of power system related problems. As a result,\na linear and a nonlinear method for power system state estimation with\nsimultaneous treatment of the conventional and synchrophasor measurements have\nbeen proposed. In this paper, new circuit models are introduced for different\ncombinations of conventional measurements, thus providing a complete modelling\nframework for these methods. Additionally, handling cases of null injections\nand buses with no measurements are included. Simulations are performed on\nseveral test systems in order to evaluate the performance of both methods with\nthe enhanced modelling framework and to compare them to a hybrid constrained\nestimator based on the conventional WLS approach.\n
