Comparative Analysis of Optimal Capacitor Placement and D-STATCOM towards Power Consumption and Power Loss Minimization

Abstract

The current situation presents the power utilities with a tremendous challenge: meeting an exponential increase in electricity consumption. Volt-VAr optimization (VVO) is a technique for maximizing efficiency by coordinating voltage and reactive power. In this work, Conservation Voltage Reduction (CVR) is coordinated with different VAr management schemes to maximize reduction in the total power losses and power consumption of the system. The suggested approach is applied on an exponential load model. To evaluate technical benefits three different cases have been performed on IEEE-33 bus system. Rao-1 optimization technique is applied to determine best size and position of both shunt capacitor and D-STATCOM. In comparison to other cases, the simulated results suggest that CVR and VAr control utilising D-STATCOM can maximize reduction in power losses and power demand.
