Optimal Allocation of PV Based DG in Distribution Networks at Different Load Levels

Nowadays, renewable energy sources especially photovoltaic (PV) based distributed generation (DG) highly increased in distribution system. This paper study the performance of distribution system when single and multiple PV based DG are integrated in distribution networks at different load levels (light, nominal and peak). The best location and size of DG in distribution system is determined to reduce the total power losses and improve the system voltage profile. To achieve this target, Augmented Grey Wolf Optimizer (AGWO) and Loss Sensitivity Factor (LSF) is proposed. The proposed algorithm has been validated using IEEE 69-bus radial distribution system (RDS). The obtained results show the effectiveness of the proposed algorithm.
