Consumption Manner Effect on Renewable DG Allocation in Reconfigurable Distribution Systems

Abstract

Distributed generation (DG) allocation in reconfigurable electric energy systems is an efficient way for energy loss reduction in modern power systems. On the other side, load profile and electricity consumption method affect the amount of energy losses in such systems. Consequently, power demand fluctuations have a fundamental role in determining energy loss value and, therefore, the network topology and optimal generation of DG units. Nevertheless, load variability consideration in DG allocation of reconfigurable networks significantly increases the computational efforts and processing time, while its neglect causes inaccurate calculation of energy losses. Accordingly, the present paper intends to assess the impact of consumption patterns on renewable DG allocation and switching plans to find out the importance of load variations consideration in minimizing power losses via DG placement and network topology modification. The AMPL, as an important classic optimization tool, was used for the analysis of the proposed idea in several distribution systems.
