Abstract: Distributed Generation sources (DG) penetration in power system has seen phenomenal increase in recent times. Distribution system performance improves if DG’s are placed at optimal locations. As distribution network configuration greatly affect its operating conditions, network configuration and optimal location for DG needs to be analyzed concurrently. This research presents a recent meta-heuristic Biogeography Based Optimization (BBO) to minimize the power loss and improve voltage profile by identifying optimal switching combinations and DG allocation. Loss sensitivity analysis is performed to find the optimal locations for DG allocation. Load flow is carried out using backward forward sweep method. The objective is evaluated subject to operating limitations of the system. The proposed method has been tested on IEEE-33 bus radial distribution system under different operating conditions of DG placement and configuration. The results demonstrate the efficacy of the proposed method.
