Chance-constrained optimal power flow with non-parametric probability distributions of dynamic line ratings

•A chance-constrained DCOPF with non-parametric correlated probabilistic forecasts of DLR and wind power.•The model co-optimizes energy and reserves with typical risk aversion levels of TSOs.•Assuming a normal distribution overestimates the probabilistic forecasts of DLR.•DLR reduces wind power curtailment and dispatch costs in highly congested networks.
