Optimal Placement of Distributed Energy Resources and Shunt Capacitors with Consideration of Existing On-line tap changer using Honey Badger Optimization

In this study, the optimal allocation of distributed energy resources (DERs) and shunt capacitors (SCs) in the distribution network (DN) is presented. Furthermore, the effect of existing voltage regulator (VR) device such as on-line tap changer (OLTC) on the optimal deployment of DERs is examined. In this study, the objective functions considered are the cost of annual energy loss (CAEL) and deviation of node voltage. To solve the considered allocation problem, newly published heuristic optimization technique, Honey Badger Optimization (HBO), is applied. The results are obtained for the real-life India 108 bus radial distribution system. These results clearly show that more payback in terms of reduced CAEL is obtained upon the utilization of existing VR devices. The obtained results are also compared with the results presented by other optimization methods in the literature. The comparitive analysis indicates the superiority of the HBO algorithm over others, especially in terms of the reduced CAEL.
