Evaluation of Optimal Access Location and Capacity of DG for Insertion in distribution System with Condensed Power Losses showing improved Critical Bus Voltage Stipulation

Abstract

This paper intent to enhance the revenue of optimally planned distributed generation (DG) insertion in distribution system in terms of condensed active and reactive power losses, improved critical bus voltage and system voltage profile which may undeniably ensures aided load expansion and system stability. The novelty of this paper is a multi-objective approach based on two port transmission parameters for optimally determining the size and access point for DG insertion in distribution system. To validate the proposed method the results obtained are compared with already published Analytical Method and the well known Exhaustive Load Flow method. The Comparative study presented has shown that the proposed method leads existing methods in terms of its ease, reduced computational time and handling less number of variables. Despite of that cross verification of results with multi-objective approach assures the optimality of estimated parameters with improved efficiency. To exhibit the utility of the method, it is implemented on standard IEEE 16 bus, 33 bus and 69 bus test radial distribution systems. The simulation is carried out in MATLAB environment for execution of the proposed algorithm.
