Contingency Analysis Based on Partitioned and Parallel Holomorphic Embedding
Rui Yao, Feng Qiu, Kai Sun
In the steady-state contingency analysis, the traditional Newton-Raphson method suffers from non-convergence issues when solving post-outage power flow problems, which hinders the…
On Periodical Damping Ratio of a Controlled Dynamical System with Parametric Resonances
Xin Xu, Kai Sun
This report provides an interpretation on the periodically varying damping ratio of a dynamical system with direct control of oscillation or vibration damping. The principal parame…
A Dynamized Power Flow Method based on Differential Transformation
Yang Liu, Kai Sun, Jiaojiao Dong
This paper proposes a novel method for solving and tracing power flow solutions with changes of a loading parameter. Different from the conventional continuation power flow method,…
Adaptive Switching Control of Wind Turbine Generators for Necessary Frequency Response
Yang Liu, Yichen Zhang, Kai Sun +1
This letter proposes a new control strategy for wind turbine generators to decide the necessity of switches between the normal operation and frequency support modes. The idea is to…
Differential Transformation of Nonlinear Power Flow Equations
Yang Liu, Kai Sun
Differential transformation (DT) method has shown to be promising for power system simulation in our recent works. This letter applies the DT method to nonlinear power flow equatio…
A Network Decoupling Method for Voltage Stability Analysis Based on Holomorphic Embedding
Qiupin Lai, Chengxi Liu, Kai Sun
This paper proposes a network decoupling method based on Holomorphic Embedding (HE) for voltage stability analysis. Using the proposed HE method with a physical load scaling factor…
