Abstract—Active and reactive power losses have become one of the most challenging in power system. Loss reduction through various methods have evolved and hence improving voltage profile. One effective loss minimization method is reactive power management by placing shunt compensators at appropriate places with proper size. This paper presents a complete methodology for optimal allocation of two VAR compensator which are Static Var Compensator (SVC) and shunt capacitors to improve the overall performance of a radial primary distribution network. The impact of optimal allocation of shunt compensators on primary distribution networks performance with different load levels (20% increased or 20% decreased) is also studied. Modified IEEE 33-bus primary distribution network is used to verify the effectiveness of the proposed methodology with different load levels. Implementation of the suggested methodology is carried out by Power World Simulator (PWS). The outcome of this work helps in design and operational reactive power planning for the voltage and reactive power management
