Abstract

Placement of multiple distributed generators (DG) in distribution system is addressed in this paper. A multiobjective index, formulated by combining the appropriately weighed diverse performance indices, is evaluated using Genetic Algorithm to assess the suitable locations and sizes of DG units to be placed. The impact of DG model on DG siting and sizing are also addressed considering different voltage dependent load models. The simulation study is carried out on a typical 25 bus Indian system and the results of the study show that the DG model significantly affects the placement location, size of the unit and penetration level (sum of the size of DG units) in a distribution system.
