Gil-González, "Power Flow in Bipolar DC Distribution Networks Considering Current Limits," in IEEE Transactions on Power Systems, vol. 37, no. 5, pp. 4098-4101, Sept. 2022, doi: 10.1109/TPWRS.2022.3181851.https://hdl.handle.net/20.500.12585/12310Power electronics converters are equipped with current controls that protect the converter from over-currents. This protection introduces non-differentiable equations into the power flow problem. The conventional Newton's method is not suitable in that conditions. This letter proposes a fixed-point iteration to overcome this difficulty. The technique is derivative-free, and hence, it can naturally include the saturation given by the converters' current protection. Exact conditions for convergence and uniqueness of the solution are demonstrated using Banach's fixed point theorem.
