Effect of change in number and power factor of DG on optimal allocation for minimal actual power loss in RDS

Abstract

Due to its remarkable techno-economic advantages, Distributed Generator (DG) penetration is growing drastically. To minimize the power losses and enhance the voltage profile, determining the precise size & position of DG is critical. The proposed paper compares the effect of variations in the number & power factor of DG on its optimal allocation in the Radial Distribution System (RDS) for minimizing the active power loss & enhancing the voltage profile using Grey Wolf Optimization (GWO) algorithm. The Direct Load Flow (DLF) approach is applied to address the system's power flow. Under altering DG parameters, the proposed method computes and compares appropriate DG allocation in standard IEEE 33 & 69 bus RDS.
