An analytical approach for optimal placement and sizing of Distributed Generation based on a combined voltage stability index

With the elevated loading and incremental demand for electrical energy, distributed energy resources (DER) such as solar photovoltaics, wind and biomass energy are becoming more pronounced in distribution systems. Location and capacity allocation of DERs have intensely impacted on the system losses in the distribution network. This paper presents an analytical approach to envisage the impact of Distributed Generation (DG) on network power losses, voltage profile and voltage stability. A detailed performance analysis is carried out on 12 node, revised 12 node and 69 node radial distribution network.
