SITING AND SIZING OF DISTRIBUTED GENERATION
UNITS USING GA AND OPF
ABSTRACT
This paper deals with the important task of finding the optimal siting and sizing of
Distributed Generation (DG) units for a given distribution network so that the cost
of active and reactive power generation can be minimized. The optimization tech-
nique is based on Genetic Algorithm (GA) and Optimal Power Flow (OPF) calcu-
lations. Using the suggested technique of this paper, the search space of GA is lim-
ited and the optimum generation condition can be achieved. The proposed proce-
dure has been applied to a distribution system and the results of simulations indi-
cate that the application of the suggested technique can result in considerable sav-
ings.
