Comparative Study of Single and Multiple Point Renewable Energy Based DG Allocation Considering Improvement of Voltage Stability, Economic and Environmental Factors Using Jaya Algorithm

Abstract

An improved, fast and simple optimization algorithm, Jaya, is applied on a multi-objective, constrained problem to find the optimal allocation of a single and two distributed generators (DG), taking care of security limits. During sizing and optimal allocation of the DG/DGs, technical, social and economic conditions have been taken into account. The objective function is based on indices namely, voltage profile enhancement index (VPEI), emission cost benefit index (ECBI) and benefit cost ratio (BCR), so as to analyze the effect of the DG/DGs on IEEE 33 and IEEE 69 bus systems. This manuscript presents a comparative study of single DG and twin DG allocation of same capacity in total as well as the performance of Jaya in calculating the optimal size of DG considering the technical, social and economic impacts.
