Power system load modelling

This paper describes the progress that has been made by the authors in developing a device and a technique for power system load modelling. The applications developed under the FACTS initiative and the system identification technique using the correlation method with pseudo random sequences (PRS) have been adopted for signal injection and load modelling. Simulation studies for load modelling using PSCAD and Matlab have been carried out. Simulation results have shown that the proposed method is promising, and the design of the device for the injection of the pseudo random signal and the method used for load identification are successful
