 Abstract—This paper presents a new combined technique for

minimizing the power loss in distribution system by optimal

Distributed Generation (DG) installation together with capacitor

placement. Sensitivity analysis is used to identify the optimal

candidate locations of DGs and capacitor placement. Bacterial

Foraging Optimization Algorithm (BFOA) is applied to find the

optimal size of DGs and capacitors. BFOA is a swarm intelligence

technique which models the individual and group foraging

policies of the E. coli bacteria as a distributed optimization

process. The technical constraints of voltage and branch current

carrying capacity are included in the assessment of the objective

function. Different cases of DG and capacitor placement are

considered to assess the performance of the proposed method.

Proposed method has been tested on IEEE 33-bus radial

distribution system and the results obtained are encouraging.
