Assessing the Optimality of LinDist3Flow for Optimal Tap Selection of Step Voltage Regulators in Unbalanced Distribution Networks
Krishna Sandeep Ayyagari, Sherin Ann Abraham, Yiyun Yao +4
The adoption of distributed energy resources such as photovoltaics (PVs) has increased dramatically during the previous decade. The increased penetration of PVs into distribution n…
Observers for Differential Algebraic Equation Models of Power Networks: Jointly Estimating Dynamic and Algebraic States
Sebastian Nugroho, Ahmad Taha, Nikolaos Gatsis +1
Phasor measurement units ({PMUs}) have become instrumental in modern power systems for enabling real-time, wide-area monitoring and control. Accordingly, many studies have investig…
Revisiting the Water Quality Sensor Placement Problem: Optimizing Network Observability and State Estimation Metrics
Ahmad F. Taha, Shen Wang, Yi Guo +4
Real-time water quality (WQ) sensors in water distribution networks (WDN) have the potential to enable network-wide observability of water quality indicators, contamination event d…
State Estimation in Water Distribution Networks through a New Successive Linear Approximation
Shen Wang, Ahmad F. Taha, Lina Sela +2
State estimation (SE) of water distribution networks (WDNs) is difficult to solve due to nonlinearity/nonconvexity of water flow models, uncertainties from parameters and demands,…
Receding Horizon Control for Drinking Water Networks: The Case for Geometric Programming
Shen Wang, Ahmad F. Taha, Nikolaos Gatsis +1
Optimal, network-driven control of Water Distribution Networks (WDN) is very difficult: valve and pump models form non-trivial, combinatorial logic; hydraulic models are nonconvex;…
Tuning-Free, Low Memory Robust Estimator to Mitigate GPS Spoofing Attacks
Junhwan Lee, Ahmad F. Taha, Nikolaos Gatsis +1
The operation of critical infrastructures such as the electrical power grid, cellphone towers, and financial institutions relies on precise timing provided by stationary GPS receiv…
