Description
Summary:•A detailed EMT-type component-based load model is capable of almost accurately reproducing the measured dynamic behavior of load during and following a voltage sag.•Using measured data to derive relevant characteristics of the modelled load (e.g., connection or reconnection pattern of motor loads during and following voltage sags or load torque characteristics of single-phase motors) is beneficial to provide a more realistic representation of the load.•Approximate, yet reasonable load composition can reproduce the actual measured load behavior. All circumstantial data (i.e., geographical location, time, temperature, etc.) should be accounted for to achieve the best estimate of load composition. Nevertheless, load component data will always have some uncertainty no matter how hard one tries to obtain this information. Load modeling is one of the most important parts in power system simulation. This paper describes the efforts to develop a detailed EMT-type component-based load model. The aim of this new model is to capture the accurate behavior of loads in commercial and residential sectors. The developed model is validated and refined against field data which were recorded by Hydro-Quebec during voltage sag events. The simulations are performed using the time-domain simulation tool EMTP.
