Placement of DG and Capacitor for Loss Reduction, Reliability and Voltage Improvement in Distribution Networks Using BPSO

Abstract

This paper presents mult i-object ive function for optimally determining the size and location of distributed generation (DG) and capacitor in distribution systems for power loss minimizat ion, reliability and voltage imp rovement. The objective function proposed in this paper includes reliab ility index, active power loss index, DG's and capacitor's investment cost index and voltage profile index which is minimized using binary particle swarm optimization algorith m (BPSO). The effectiveness of the proposed method is examined in the 10 and 33 bus test systems and comparative studies are conducted before and after DG and capacitor installation in the test systems. Results illustrate significant losses reduction and voltage profile and reliab ility imp rovement with presence of DG unit and capacitor.
