Distribution system voltage regulation and var compensation for different static load models

Voltage regulation computations for distribution systems are strongly dependent an power flow solutions. The classical constant power load model is typically used in power flow studies of transmission or distribution systems; however, the actual load of a distribution system cannot just be modeled using constant power models, requiring the use of constant current, constant impedance, exponential or a mixture of all these load models to accurately represent the load. This paper presents a study of voltage regulation of a distribution system using different static load models. The effect of shunt capacitor compensation is also studied and illustrated in this paper far systems with different static load models.
