Abstract

Distributed Generation (DG) technology has emerged as a key important issue in distribution system planning, reliability and optimization for quite sometime now. Apart from economic power generation and its efficient transfer, major interests have been observed to plan the distribution system with the presence of small energy sources. This paper addresses a novel technique for optimal placement and sizing of DG into electric power distribution systems. Emphasis has been made to find the impact on voltage profile and power loss of the distribution network with different DG locations and sizes subject to satisfaction of network security constraints. A power flow based simple mathematical formulation has been made. Programs were developed in Matlab for solving the problem. Results reveal that while finding the optimal location and sizing of a DG in a distribution system, both power loss and network security aspects of the network must be considered in addition to minimum voltage deviation as they influence the optimal results significantly.
