Optimal Unified Power Quality Conditioner Allocation in Distribution Systems for Loss Minimization using Grey Wolf Optimization
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 11
Abstract
Compensation in power systems is essential to reduce the power loss and maintain the voltage profile. Reactive power compensation and voltage compensation are the different compensation techniques available in power systems. Series compensators aid to maintain the voltage profileby providing voltage compensation. Shunt compensators aid to reduce the power losses occurring in the networkby providing reactive power compensation. The functioning of series and shunt compensators are integrated in a device known as Unified Power Quality Conditioner (UPQC). This paper throws light on the loss reduction aspect of UPQC by determining the placement of UPQC using a single objective function of minimization of power losses. The voltage improvement aspect of UPQC is highlighted by determining the number of under voltage nodes in the network. The optimal location and rating of UPQC are obtained by Grey Wolf Optimization (GWO) method. UPQC is incorporated in Backward/Forward Sweep Load Flow method to determine the power flows in the branches and voltages at the nodes. MATLAB software is used to highlight the efficiency of the proposed device in two distribution systems.
