Özet

In this study, a comprehensive investigation was carried out on ZIP models to represent the voltage-dependent behavior of residential electrical loads. To accurately capture the intrinsic dynamic responses of the selected appliances, a measurement-driven methodology was implemented, enabling a more precise and reliable characterization of their load behavior. The ZIP framework, widely employed for estimating the active and reactive power drawn by loads under varying voltage conditions, constitutes a fundamental modeling approach grounded in the physical representation of the power–voltage relationship. As part of this study, six commonly used household appliances were experimentally examined in the Electrical Laboratory of Karadeniz Technical University, Trabzon Vocational School. The appliances were tested across a voltage range of 180 V to 250 V in 10V increments. At each voltage level, a high-resolution set of electrical parameters was recorded with a temporal resolution of one second. The acquired dataset was subsequently processed in MATLAB using the least-squares estimation technique, through which the ZIP coefficients for each appliance were derived. In the final stage of this study, the power values predicted by the obtained ZIP models were compared with their measured counterparts. This comparison enabled a rigorous evaluation of the accuracy and representational capability of the models in describing the voltage-dependent power behavior of residential loads.
