Managing Vehicle Charging During Emergencies via Conservative Distribution System Modeling
Alejandro D. Owen Aquino, Samuel Talkington, Daniel K. Molzahn
Combinatorial distribution system optimization problems, such as scheduling electric vehicle (EV) charging during evacuations, present significant computational challenges. These c…
A Decomposition Algorithm for Large-Scale Security-Constrained AC Optimal Power Flow
Frank E. Curtis, Daniel K. Molzahn, Shenyinying Tu +3
A decomposition algorithm for solving large-scale security-constrained AC optimal power flow problems is presented. The formulation considered is the one used in the ARPA-E Grid Op…
Verifying Global Optimality of Candidate Solutions to Polynomial Optimization Problems using a Determinant Relaxation Hierarchy
Sikun Xu, Ruoyi Ma, Daniel K. Molzahn +2
We propose a method for verifying that a given feasible point for a polynomial optimization problem is globally optimal. The approach relies on the Lasserre hierarchy and the resul…
Robust AC Optimal Power Flow with Robust Convex Restriction
Dongchan Lee, Konstantin Turitsyn, Daniel K. Molzahn +1
Electric power grids regularly experience uncertain fluctuations from load demands and renewables, which poses a risk of violating operational limits designed to safeguard the syst…
Balancibility: Existence and Uniqueness of Power Flow Solutions under Voltage Balance Requirements
Bowen Li, Bai Cui, Feng Qiu +1
In distribution systems, power injection variability due to growing penetrations of distributed energy resources (DERs) and dispatchable loads can lead to power quality issues such…
Tightening QC Relaxations of AC Optimal Power Flow Problems via Complex Per Unit Normalization
Mohammad Rasoul Narimani, Daniel K. Molzahn, Mariesa L. Crow
Optimal power flow (OPF) is a key problem in power system operations. OPF problems that use the nonlinear AC power flow equations to accurately model the network physics have inher…
