A Linear LMP Model for Active and Reactive Power with Power Loss
Yanghao Yu, Qingchun Hou, Yi Ge +2
Pricing the reactive power is more necessary than ever before because of the increasing challenge of renewable energy integration on reactive power balance and voltage control. How…
A Deep Reinforcement Learning Based Approach for Optimal Active Power Dispatch
Jiajun Duan, Haifeng Li, Xiaohu Zhang +6
The stochastic and dynamic nature of renewable energy sources and power electronic devices are creating unique challenges for modern power systems. One such challenge is that the c…
Bayesian Estimation Based Parameter Estimation for Composite Load
Chang Fu, Zhe Yu, Di Shi +4
Accurate identification of parameters of load models is essential in power system computations, including simulation, prediction, and stability and reliability analysis. Convention…
Sensitivity Based Thevenin Index for Voltage Stability Assessment Considering N-1 Contingency
Xiaohu Zhang, Di Shi, Xiao Lu +3
This paper proposes an approach to address the voltage stability assessment (VSA) considering N-1 contingency. The approach leverages the sensitivity based Thevenin index (STI) whi…
An Extended Kalman Filter Enhanced Hilbert-Huang Transform in Oscillation Detection
Zhe Yu, Di Shi, Haifeng Li +3
Hilbert-Huang transform (HHT) has drawn great attention in power system analysis due to its capability to deal with dynamic signal and provide instantaneous characteristics such as…
Online Coherence Identification Using Dynamic Time Warping for Controlled Islanding
Hasan Ul Banna, Zhe Yu, Di Shi +5
Controlled islanding is considered to be the last countermeasure to prevent system-wide blackouts in case of cascading failures. It splits the system into self-sustained islands to…
