Abstract

DGs Technology has become the center of attention of the researchers and engineers because it is considered as an appropriate solution to overcome the shortage of electricity supply and power quality problems. DGs placement in appropriate locations with the right type and size is a challenging issue. This research discusses the simultaneous placement and sizing of multi-types of DGs in unbalanced radial distribution systems for power loss reduction and voltage deviation improvement while maintaining harmonics at the standard limit. The optimizations are performed simultaneously on three parameters; the locations, the types and the sizes of DGs. Genetic Algorithm (GA) is employed to ensure the optimal point is reached. The proposed method is applied on Kaliasin East Java radial distribution systems. The results show that the placement of four DGs type III are the most effective in reducing power loss and …
