Sequential quadratic programming models for solving the OPF problem in DC grids

open access: yesElectric power systems research, 2019
In this paper, we address the optimal power flow problem in dc grids (OPF-DC). Our approach is based on sequential quadratic programming which solves the problem associated with non-convexity of the model.
