Efficient Identification of Bus Split Events Using Synchrophasor Data
Yuqi Zhou, Hao Zhu
Accurate grid topology information is of paramount importance for routine power system operations, while the growing availability of synchrophasor data offers the opportunity to id…
Substation-Level Grid Topology Optimization Using Bus Splitting
Yuqi Zhou, Ahmed S. Zamzam, Andrey Bernstein +1
Operations of substation circuit breakers are important for maintenance needs and topology reconfiguration in power systems. Bus splitting is one type of topology change where the…
Transmission Switching Under Wind Uncertainty Using Linear Decision Rules
Yuqi Zhou, Hao Zhu, Grani A. Hanasusanto
Increasing penetration of wind and renewable generation poses significant challenges to the power system operations and reliability. This paper considers the real-time optimal tran…
Optimal Power Flow with Step-Voltage Regulators in Multi-Phase Distribution Networks
Mohammadhafez Bazrafshan, Nikolaos Gatsis, Hao Zhu
This paper develops a branch-flow based optimal power flow (OPF) problem for multi-phase distribution networks that allows for tap selection of wye, closed-delta, and open-delta st…
Dynamic Distribution State Estimation Using Synchrophasor Data
Jianhan Song, Emiliano Dall'Anese, Andrea Simonetto +1
The increasing deployment of distribution-level phasor measurement units (PMUs) calls for dynamic distribution state estimation (DDSE) approaches that tap into high-rate measuremen…
Hybrid Voltage Control in Distribution Networks Under Limited Communication Rates
Hao Jan Liu, Wei Shi, Hao Zhu
Voltage regulation in distribution networks is challenged by increasing penetration of distributed energy resources (DERs). Thanks to advancement in power electronics, these DERs c…
