Investigation on Optimal Placement and Sizing of Distributed Generation Units Using Optimization Technique

Distributed Generation (DG) has gained more importance to meet the increased load demand. Its integration in a distribution system in comparison to conventional system stacks numerous potential benefits related to losses reduction, improvement in voltage profile, etc. Few important issues involved with distributed generation are placement, sizing, its rating, mode of operation and technology etc. This paper focuses on one of the issue that is optimal placement of DG unit as the allocation of DG units at inappropriate places results in increase in system loss and also reduction in bus voltage profile. Alternative sources of energy based distributed generation has one of the considerable benefit as environmental friendliness. Hence, allocation of distributed generation units in proper place is an important aspect for maximizing the benefits stated above.
