Load Modeling in Power Systems Using WAMS Measurement System

Modern power systems are characterized by their complexity, nonlinearity, and dynamic nature, making their analysis heavily reliant on advanced computational techniques. The reliability and accuracy of power system simulations are significantly influenced by the models of the components involved, with load models playing a crucial role, especially in dynamic simulations. Inaccurate load models can lead to unreliable outcomes in power flow, short circuit, and stability studies. This study investigates load modeling using the Wide Area Measurement System (WAMS). A comprehensive system-wide load modeling strategy is proposed, selecting output variables of the power system. The goal function is developed utilizing WAMS data, and parameters are efficiently estimated using a sophisticated parameter estimation method. This approach is applied to the IEEE 14 bus system to assess its performance compared to conventional load modeling techniques.
