Linear State and Parameter Estimation for Power Transmission Networks
In this paper, a linear framework for the combined state and parameter estimation of an electric power grid observed both by conventional and synchrophasor measurements is proposed. The method can be used for estimating parameters of transmission lines, tap-changers and shunts, while providing unbiased estimates of the bus voltages. The network components with incorrect parameters are identified via measurement residuals. The accuracy of the proposed method is evaluated for various cases of bad parameters using the IEEE 118 bus test system.
