Optimum siting and sizing of a large distributed generator in a mesh connected system

This paper proposes a new approach to optimally determine the appropriate size and location of the distributed generator (DG) in a large mesh connected system This paper presents a visual optimization approach in which the planner plays an important role in deter mining the optimal siting and sizing of the DG through the choice of the appropriate weight factors of the parameters included in the optimization technique according to the system deficiencies. Losses, voltage profile and short circuit level are used in the algorithm to determine the optimum sizes and locations of the DG The short circuit level parameter is Introduced to represent the protective device requirements in the selection of the size and location of the DG The proposed technique has been tested on the IEEE 24 bus mesh connected test system The obtained results showed clearly that the optimal size and location can be simply determined through the proposed approach (C) 2009 Elsevier BV All rights reserved
