An experimental study on the load modelling using PMU measurements

Proper load modelling has significant effect on various power system studies. Due to faster refresh rate and high accuracy of the measurements, phasor measurement units (PMUs) have potential to significantly improve the existing load modelling practice. This paper presents an experimental study on modelling the loads in a university environment by using measurements obtained from the PMUs. Both static and dynamic load models are considered in this study. The load model parameters are found by minimizing the sum of square of errors between the measurement and the model output by using suitable optimization algorithm. Promising results are obtained from the experimental studies as well as on studies conducted on Real Time Digital Simulator(RTDS®).
