Not All Warm Starts Help: Benchmarking Primal-Dual Initializations for ACOPF Algorithms
Babak Taheri, Daniel K. Molzahn
Warm starts are widely used to accelerate AC optimal power flow (ACOPF) solves, but the impact of different initialization strategies has received limited systematic study, particu…
Improving the Accuracy of DC Optimal Power Flow Formulations via Parameter Optimization
Babak Taheri, Daniel K. Molzahn
DC Optimal Power Flow (DC-OPF) problems optimize the generators' active power setpoints while satisfying constraints based on the DC power flow linearization. The computational tra…
Optimizing Parameters of the LinDistFlow Power Flow Approximation for Distribution Systems
Babak Taheri, Rahul K. Gupta, Daniel K. Molzahn
The DistFlow model accurately represents power flows in distribution systems, but the model's nonlinearities result in computational challenges for many applications. Accordingly,…
AC-Informed DC Optimal Transmission Switching Problems via Parameter Optimization
Babak Taheri, Daniel K. Molzahn
Optimal Transmission Switching (OTS) problems minimize operational costs while treating both the transmission line energization statuses and generator setpoints as decision variabl…
