Topology and Admittance Estimation: Precision Limits and Algorithms
Yuxiao Liu, Ning Zhang, Qingchun Hou +2
Distribution grid topology and admittance information are essential for system planning, operation, and protection. In many distribution grids, missing or inaccurate topology and a…
Sparse Oblique Decision Tree for Power System Security Rules Extraction and Embedding
Qingchun Hou, Ning Zhang, Daniel S. Kirschen +3
Increasing the penetration of variable generation has a substantial effect on the operational reliability of power systems. The higher level of uncertainty that stems from this var…
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…
Embedding Lithium-ion Battery Scrapping Criterion and Degradation Model in Optimal Operation of Peak-shaving Energy Storage
Qingchun Hou, Yanghao Yu, Ershun Du +5
Lithium-ion battery systems have been used in practical power systems for peak-shaving, demand response, and frequency regulation. However, a lithium-ion battery is degrading while…
Probabilistic duck curve in high PV penetration power system: Concept, modeling, and empirical analysis in China
Qingchun Hou, Ning Zhang, Ershun Du +3
The high penetration of photovoltaic (PV) is reshaping the electricity net-load curve and has a significant impact on power system operation and planning. The concept of duck curve…
