On Distribution Grid Optimal Power Flow Development and Integration
Sarmad Hanif, Rabayet Sadnan, Tylor E. Slay +8
Due to changes in electric distribution grid operation, new operation regimes have been recommended. Distribution grid optimal power flow (DOPF) has received tremendous attention i…
Estimating Driver Response Rates to Variable Message Signage at Seattle-Tacoma International Airport
Soumya Vasisht, Shushman Choudhury, Nawaf Nazir +2
We apply Bayesian Linear Regression to estimate the response rate of drivers to variable message signs at Seattle-Tacoma International Airport, or SeaTac. Our approach uses vehicle…
Optimization-Based Resiliency Verification in Microgrids via Maximal Adversarial Set Characterization
Nawaf Nazir, Thiagarajan Ramachandran, Saptarshi Bhattacharya +3
Critical energy infrastructures are increasingly relying on advanced sensing and control technologies for efficient and optimal utilization of flexible energy resources. Algorithmi…
Guaranteeing a physically realizable battery dispatch without charge-discharge complementarity constraints
Nawaf Nazir, Mads Almassalkhi
The non-convex complementarity constraints present a fundamental computational challenge in energy constrained optimization problems. In this work, we present a new, linear, and ro…
Optimal and resilient coordination of virtual batteries in distribution feeders
Sarnaduti Brahma, Nawaf Nazir, Hamid Ossareh +1
This paper presents a novel hierarchical framework for real-time, network-admissible coordination of responsive grid resources aggregated into virtual batteries (VBs). In this cont…
Stochastic multi-period optimal dispatch of energy storage in unbalanced distribution feeders
Nawaf Nazir, Mads Almassalkhi
This paper presents a convex, multi-period, AC-feasible Optimal Power Flow (OPF) framework that robustly dispatches flexible demand-side resources in unbalanced distribution feeder…
