A time-domain approach for distribution and transmission network modeling

A state variable approach based on a time-domain analysis is presented for identifying the parameters of a distribution or transmission network model using actual recorded data. The data used in the model development were simulated data and actual recorded data. The actual recorded data were obtained during normal operating and capacitor switching conditions in a primary distribution feeder. The method describes the network in state variable format, which is applicable to steady-state and transient conditions. The conversion of state variable representation to frequency-domain impedance transfer functions is also presented
