The load flow calculation mainly involves for calculating the voltages at each load points and real and reactive power losses across each branch. 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 profile improvement and power loss reduction for constant power type of load model. Keywords: Distribution systems, Load flow, static load models, voltage profile, and power loss.
