Dynamic Load Modelling Using Real Time Estimated States

1. KIOS Center of Excellence, University of Cyprus

Dynamic load models are necessary for accurate monitoring and control of the system during various events as well as for better understanding the behavior and the characteristics of the system. In this paper, a realistic approach of load modelling using real time estimated states is studied. Since Phasor Measurement Units (PMUs) are not installed yet at every bus, a linear state estimator is used to provide the state of the buses without PMUs. The overall impact of the real time estimated states and the inaccurate load model parameters are studied on the IEEE 39-bus dynamic test system. In addition, the realistic approach of load modelling is enhanced by using various load types while errors that affect the estimated states, such as line parameter errors and measurement gross errors are also considered. Furthermore, a sensitivity analysis with inaccurate load model parameters is performed to show their effect on the results of load modelling.
