  title={Decentralized Model-free Loss Minimization in Distribution Grids with the Use of Inverters},
  author={Ilgiz Murzakhanov and Spyros Chatzivasileiadis},
Nowadays, distribution grids are undergoing massive penetration of renewable energy sources (RESs), especially rooftop photovoltaic solar panels (PVs) and small wind turbines (WTs), which lead to a greater ratio of fluctuating generation. As a result, the inherited problems of distribution grids, such as poor voltage profile and high power losses, become even worse due to bidirectional flows. To operate a grid in the optimal mode, we propose a communication- and model-free algorithm that…
