This research article proposes a unique planning strategy of reactive power (VAr) considering static load model in power transmission system. An exponential static load model of active and/ or reactive power is considered during the study of load flow solution through Newton-Raphson method. This load model is designed with active and reactive exponents on the flow of active and reactive power through the transmission network. The power losses from load flow solution is measured and minimized through the proper placement of compensation devices. Here two types of FACTS (flexible ac transmission systems) are used in order to compensate reactive power. The separate and collective effect of active and reactive power modeling on load flow is also observed during the calculation of total operating cost (TOC) of the system. The TOC is formulated mathematically by adding different cost components such as cost due to real power loss, VAr generation cost component, compensation device cost component. To validate the impetus of the proposed planning strategy small, medium and large transmission systems are considered in this research work.
