The paper presents comparative studies of state estimation for a power system with and without the UPFC device. Weighted least squares state estimation is considered. Such parameters of state estimation are taken into account as: the condition number of the gain matrix, parameters characterizing accuracy of estimation results, and number of iterations in a computational process. During investigation,...
The paper presents a comparative investigations of the state estimation of a power system with UPFC in the polar and rectangular coordinate systems, paying special attention to types of utilized measurements. The estimation with the use of the weighted-least-squares method is considered. During investigations, impact of a coordinate system, in which the state vector is considered, stress of a power...
