Abstract: Extensive penetration of distributed generation (DG) is one of the critical challenges near future for efficient and low carbon energy utilization in the world. Since DG installation greatly influences existing power systems, it is required to install DG with suitable location and adequate size, thus some decision-making tools for optimal DG installation are necessary.
This paper presents a new approach for optimal location and sizing of DG. Although approximate methods are generally adopted in this area because of the problem difficulty arising from the combinational nature, an exact enumerative method is proposed in this paper because of its simplicity and versatility. The usefulness of this enumerative method is demonstrated in a simple pilot system and some quantitative/qualitative characteristics in DG installation are also clarified..

Keywords: Distributed generation, optimal location, power loss reduction, exact solution method
