Replicating Real-World 23-Hz Oscillations Caused by Large Electronic Loads
Lingling Fan, Ali Yazdanpanah, Yunzhi Cheng +5
In 2024, Texas operators observed 23-Hz oscillations in real power measurements close to a large electronic load (LEL). Oscillations emerged when the load's power consumption reach…
GridSweep Simulation: Measuring Subsynchronous Impedance Spectra of Distribution Feeder
Lingling Fan, Zhixin Miao, Jason MacDonald +1
Peaks and troughs in the subsynchronous impedance spectrum of a distribution feeder may be a useful indication of oscillation risk, or more importantly lack of oscillation risk, if…
Real-Time Simulation of Level 1, Level 2, and Level 3 Electric Vehicle Charging Systems
Li Bao, Lingling Fan, Zhixin Miao
A charging system is required to convert ac electricity from the grid to dc electricity to charge an electric vehicle (EV) battery. According to the Society of Automatic Engineers…
A Modular Small-Signal Analysis Framework for Inverter Penetrated Power Grids: Measurement, Assembling, Aggregation, and Stability Assessment
Lingling Fan, Zhixin Miao
Unprecedented dynamic phenomena may appear in power grids due to higher and higher penetration of inverter-based resources (IBR), e.g., wind and solar photovoltaic (PV). A major ch…
SOCP Convex Relaxation-Based Simultaneous State Estimation and Bad Data Identification
Hossein Ghassempour Aghamolki, Zhixin Miao, Lingling Fan
Traditional largest normalize residual (LNR) test for bad data identification relies on state estimation residuals and thus can only be implemented after running Power System State…
Achieving SDP Tightness Through SOCP Relaxation with Cycle-Based SDP Feasibility Constraints for AC OPF
Lingling Fan, Hossein Ghassempour Aghamolki, Zhixin Miao +1
In this paper, we show that the standard semidefinite programming (SDP) relaxation of altering current optimal power flow (AC OPF) can be equivalently reformulated as second-order…
Least Square Estimation-Based SDP Cuts for SOCP Relaxation of AC OPF
Zhixin Miao, Lingling Fan, Hossein Ghassempour +1
This paper presents a method that generates affine inequalities to strengthen the second-order conic programming (SOCP) relaxation of an alternating current optimal power flow (AC…
Achieving Economic Operation and Secondary Frequency Regulation Simultaneously Through Feedback Control
Zhixin Miao, Lingling Fan
This article presents an exciting finding for the power industry: the parameters of secondary frequency control based on integral or proportional integral control can be tuned to a…
Dual Decomposition-Based Privacy-Preserving Multi-Horizon Utility-Community Decision Making Paradigms
Vahid. R Disfani, Zhixin Miao, Lingling Fan +1
Two types of privacy-preserving decision making paradigms for utility-community interactions for multi-horizon operation are examined in this paper. In both designs, communities wi…
Least Squares Estimation-Based Synchronous Generator Parameter Estimation Using PMU Data
Bander Mogharbel, Lingling Fan, Zhixin Miao
In this paper, least square estimation (LSE)-based dynamic generator model parameter identification is investigated. Electromechanical dynamics related parameters such as inertia c…
