Loss Allocation reduction to customers by optimal location and sizing of DG in electrical distribution systems

Abstract

This paper deals radial distribution system power losses allocation to connected consumers before and after distribution generator (DG) in a deregulated environment. Allocation of power loss is made in a proposed exact method way, which is calculated based on allocating power losses to consumers by taking each branch current suppling to customer load from substation to customer load. Proposes a new methodology to reduce the burden of loss allocation to customers by allocating the optimal DG size at best location. The best location derive based on highest value line of power stability index (PSI) and increase in small steps of DG values in best location obtain the optimal DG size at the best location. The impact of DG on voltage profile, system losses and customer losses allocation are visualized by an analytical approach. The robustness and scalability of proposed method is tested on 12 bus and 69-bus radial distribution networks and compared with the existing Golden Section Search (GSS) algorithm

Novel Technique for Optimal Placement and Sizing of DG in 3-Phase Unbalanced Radial Secondary Distribution System

“…Furthermore, a supervised BB-BC algorithm proposed to precisely determining the optimum location of the DG in the unbalanced distribution network to reduce the energy losses. A solution for the effect of DG on real power losses for consumers connected to the radial distribution system depends on the exact allocation of losses in [5], a new algorithm proposed for DG location and sizing. The algorithm is based on a PSI to identify the most sensitive bus and minimum power losses.…”
