Online Voltage Stability Assessment for Load Areas Based on the Holomorphic Embedding Method
TL;DR: In this paper, an online steady-state voltage stability assessment scheme is proposed to evaluate the proximity to voltage collapse at each bus of a load area using a non-iterative holomorphic embedding method.
Journal ArticleDOI
Multi-Stage Holomorphic Embedding Method for Calculating the Power-Voltage Curve
Bin Wang,Chengxi Liu,Kai Sun +2 more
TL;DR: A multi-stage scheme to solve such a precision issue and calculate an accurate P-V curve and is verified on the New England 39-bus power system and benchmarked with the result from the traditional continuation power flow method.

Image Embedding of PMU Data for Deep Learning Towards Transient Disturbance Classification
Yongli Zhu,Chengxi Liu,Kai Sun +2 more
TL;DR: In this paper, a real synchrophasor set composing of three different types of disturbance events from the Frequency Monitoring Network (FNET) is used. And an image embedding technique called Gramian Angular Field is applied to transform each time series of event data to a two-dimensional image for learning.
