Optimal analysis of time varying load radial distribution system with photovoltaic and wind generating system using novel hybrid optimization technique

The paper proposes the optimal placement of distributed generators (DGs) in radial distribution system along with reconfiguration. The DGs which are considered in this paper are designed with photo voltaic (PV) cells and wind power generation. The paper studies on the PV and wind generation penetration in radial distribution system as per the irradiation and wind velocity throughout the day. The irradiation levels are considered throughout the day. Unlike in former hybrid optimization techniques, the place -ment of DGs and reconfiguration is shared between two optimization techniques. The paper also details the reliability improvement of radial distribution system with reconfiguration and DGs placement. Some part of reconfiguration and DG locations are selected with one optimization technique and rest of recon-figuration and DG size are selected with another optimization technique. The combination of two opti-mization techniques properties leads towards the novel hybrid optimization. The methodology is formulated with the black widow algorithm and crow search algorithm. The performance of the method is tested on two test systems which are 16 bus RDS and 33 bus RDS.(c) 2022 Elsevier Ltd. All rights reserved.
