Optimum location for operation of small size distributed generators

Abstract

Optimizing the size and finding the best location of required number of micro gas turbine running Distributed Generators (DG) to minimize the active power losses is the focus of this paper. Since the excitation field of the synchronous machines discussed in this paper is produced by permanent magnets, the reactive power is not controlled. To minimize the active power losses and satisfy the demand load, a two-stage approach has been proposed for the allocation and sizing of DGs in a distribution system with time-varying loads. The strategic placement of DGs can help to reduce energy losses and maintain the voltage within an acceptable boundary. The proposed method has been tested on a 9-bus test system.
