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…
Rejection of Smooth GPS Time Synchronization Attacks via Sparse Techniques
Erick Schmidt, Junhwan Lee, Nikolaos Gatsis +1
This paper presents a novel time synchronization attack (TSA) model for the Global Positioning System (GPS) based on clock data behavior changes in a higher-order derivative domain…
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…
A GPS spoofing detection and classification correlator-based technique using the LASSO
Erick Schmidt, Nikolaos Gatsis, David Akopian
This work proposes a global navigation satellite system (GNSS) spoofing detection and classification technique for single antenna receivers. We formulate an optimization problem at…
Probabilistic State Estimation in Water Networks
Shen Wang, Ahmad F. Taha, Nikolaos Gatsis +2
State estimation in water distribution networks (WDN), the problem of estimating all unknown network heads and flows given select measurements, is challenging due to the nonconvexi…
A New Derivative-Free Linear Approximation for Solving the Network Water Flow Problem with Convergence Guarantees
Shen Wang, Ahmad F. Taha, Lina Sela +2
Addressing challenges in urban water infrastructure systems including aging infrastructure, supply uncertainty, extreme events, and security threats, depend highly on water distrib…
