- This paper is based on the concept of coupled single port network. The paper presents a
cubic spline based approach for estimation of Thevenin parameters and uses them to compute
loading margin. The paper also presents a novel approach for consideration of reactive power
limits, which provide operator with important information regarding critical generators. (https://ieeexplore.ieee.org/document/7284716)
- This paper highlights the issues with Thevenin based equivalent for wide area voltage
stability monitoring of multi-load power systems. Authors propose a new approach called
“Coupled single port equivalent” which retains the impact of multiple loads in the system.
Impedance match theorem is then applied on the obtained 2 port equivalent. (https://ieeexplore.ieee.org/document/5875916)
- This paper builds on the theory of coupled single port network concept and presents a
modified approach. The proposed modified approach is able to deal with underestimations of
system parameters and enhance the accuracy of reported voltage stability margin. (https://ieeexplore.ieee.org/document/6632943)
- This paper builds on the theory of coupled single port network concept and presents a
modified approach. The proposed new approach deals with underestimation of 2 port network
parameters. Modified ward equivalent is utilized to deal with the underestimations. (http://ieeexplore.ieee.org/document/6672811/)
