Siting and Sizing of Capacitors in RPDF Considering Load Variations: A Profit-Based Evaluation

This is the authors' abstract. We don't add key points for this paper.

Minimizing real and reactive power losses in Radial Power Distribution Feeders (RPDF) is crucial due to a sharp increase in load demand and investment point of view. About 7% of total US power generation is lost during transmission and distribution with RPDFs in urban, semi-urban, and rural areas contributing significantly. Integrating shunt capacitors in RPDFs can reduce reactive line current, lowering losses, and enhance bus voltage profiles to achieve financial profit (FP). This paper proposes a Dandelion Optimizer to optimize reactive power support in RPDFs. No sensitivity-based indices have been considered in this work to locate optimal buses for reactive power injection. Simulation has been carried out on renowned IEEE 34-bus RPDF and found that DO outperforms other methods in the literature in terms of minimizing real power loss, bus voltage enhancement, and increased FP.
