Validation of generic models for stability analysis of two large static var systems in New York using PMU data

Abstract

This paper presents an approach for the validation of generic standard models for an SVC and a STATCOM using voltage and current data measured by phasor measurement units (PMUs) at the respective substations where these devices are installed. The data used were recorded in real-time during system disturbances at different locations of the system. By using the measured voltage, as an input to the model, the response of the model is computed and compared with the measured response of the shunt dynamic device. An optimization algorithm is used to optimally estimate the gains of the modeled controls in order to achieve good agreement between the simulated and measured response of the device. The models used in this process are generic models for static var systems developed in previous work by the WECC SVC Task Force.
