Development of a mathematical model for reactive power transmission costs in electric power systems

Abstract

The paper gives detailed analyses to help determine the increase in production costs due to the transmission of reactive power. On the basis of that and with due consideration to the cost of VARS compensation equipment, a mathematical model is developed to determine an economically justified transmission distance for VARS in electric power systems. Standard voltages and line parameters are used for the computations. MATLAB computer programming is used to obtain the numerical results. The developed mathematical model and the numerical results could be useful to electric power systems engineers.
