Extraction of Transmission Parameters for Siting and Sizing of Distributed Energy Sources in Distribution Network

Abstract EN

This paper introduces a novel method for sitting and sizing the grid connected distributed generator (DG) for installation in distribution system at any input load condition, which is based on two port transmission equations, named as modified transmission parameters (MTP) method by considering the loss minimization as a constraint.

If properly organized, with the help of various transmission parameters optimal DG allocation with minimum transmission losses, contribution of DG as well as the main supply source to each load, type of DG required to handle the existing power flow scenario, and operating power factor at which DG should operate can be easily investigated.

Apart from this the author has also investigated the worst location for DG installation and referred to it as Consecutive Bus.

The method has been tested on two test distribution systems with varying sizes and intricacy and the results have been compared with the two established methods reported earlier.

Relative study presented has shown that the proposed method leads existing methods in terms of its simplicity, computational time, and handling less number of variables.
