This paper presents a novel analytical approach to determine the optimal siting and sizing of distributed
generation ( DG ) units in balanced radial distribution network to minimize the power loss of the system.
The proposed analytical expressions are based on a minimizing the loss associated with the active and
reactive component of branch currents by placing the DG at various locations. This method first identifies
a sequence of nodes where DG units are to be placed. The optimal sizes of DG units at the identified nodes
are then evaluated by optimizing the loss saving equations and need only the results of base case load
flow. To find out the best location for DG placement, a computational method is also developed. The proposed
method has been tested and validated on two IEEE test distribution systems (DSs) consisting of 15
and 33-buses and it has been found that a significant loss saving can be obtained by placing DG units in
the system using proposed analytical method.
