Making Every Bit Count for -Optimal State Estimation
Cameron Khanpour, Daniel Turizo, Samuel Talkington
We study the problem of controlling how a limited communication bandwidth budget is allocated across heterogeneously quantized sensor measurements. The performance criterion is the…
Differentiating Through Power Flow Solutions for Admittance and Topology Control
Samuel Talkington, Daniel Turizo, Sergio A. Dorado-Rojas +2
The power flow equations relate bus voltage phasors to power injections via the network admittance matrix. These equations are central to the key operational and protection functio…
Admittance Matrix Concentration Inequalities for Understanding Uncertain Power Networks
Samuel Talkington, Cameron Khanpour, Rahul K. Gupta +5
This paper presents conservative probabilistic bounds for the spectrum of the admittance matrix and classical linear power flow models under uncertain network parameters; for examp…
Discrete Shortest Paths in Optimal Power Flow Feasible Regions
Daniel Turizo, Diego Cifuentes, Anton Leykin +1
Optimal power flow (OPF) is a critical optimization problem for power systems to operate at points where cost or other operational objectives are optimized. Due to the non-convexit…
Conditions for Estimation of Sensitivities of Voltage Magnitudes to Complex Power Injections
Samuel Talkington, Daniel Turizo, Santiago Grijalva +2
Voltage phase angle measurements are often unavailable from sensors in distribution networks and transmission network boundaries. Therefore, this paper addresses the conditions for…
Invertibility Conditions for the Admittance Matrices of Balanced Power Systems
Daniel Turizo, Daniel K. Molzahn
The admittance matrix encodes the network topology and electrical parameters of a power system in order to relate the current injection and voltage phasors. Since admittance matric…
Generator Controller Tuning Considering Stochastic Load Variation Using Analysis of Variance and Response Surface Method
Frank A. Ibarra, Daniel Turizo, César Orozco-Henao +1
This article proposes a method for generator controller tuning in a power system affected by stochastic loads. The method uses the Analysis of Variance to detect the controllers wi…
