Abstract

This paper proposes a novel approach of voltage stability enhancement and power loss minimization in addition to maintenance of good voltage profile in radial distribution networks through optimally placed distributed generation, network reconfiguration and voltage control of PQV bus through variable reactive power source at P bus. A multi-objective function has been proposed that considers maximum system loadability enhancement and network loss minimization. Optimization of proposed multi-objective function, under distributed generation and network reconfiguration with presence of PQV and P buses in the system have been done using grey wolf optimization technique. Case studies performed on IEEE 33-bus radial distribution system shows that presence of PQV and P buses in the system yields significant enhancement in voltage stability margin under optimal placement of distributed generations and network reconfiguration.

Abstract

Optimal location and sizing of different types of renewable energy generation system at the distribution networks for the purpose of active power loss minimization is revealing much attention of electric power utilities in the recent days. In the present work, optimal location and sizing of different types of renewable energy generators (REGs) have been proposed for IEEE 33-bus test system. The vastness of the REGs is determined by minimizing the power loss in the distribution system. Power distribution losses have been minimized with the determination of optimal location as well as optimum size of distributed generator. In this work, various case studies such as active power loss, reactive power loss, combined real and reactive power, optimum power factor, and multi REGs placements have been considered for optimal location of REGs. A simple but efficient Repeated Load Flow (RLF) technique has been used to ascertain optimal location of REGs. The simulation results obtained from this RLF technique have als...
