Hosting Capacity Quantification of Smart PV Inverters in Distribution Networks Based on Difference-of-Convex Programming

Smart inverters bring new reactive power regulation resources, and the control and evaluation of distribution networks have become a new problem. In this paper, we propose an optimization model to quantify the hosting capacity of smart PV inverters in distribution networks based on different-of-convex programming (DCP). First, a second-order cone programming-based model is proposed to relax the non-convex equality constraints and obtain the initial solution. Second, a DCP-based model is proposed to recover a feasible solution that eliminates the relaxation error. At last, the model is tested on a modified 13-bus system, and the results show the validity of the model.
