Nonlinear design of excitation controller and power system stabilizer for voltage regulation and transient stability

Proceedings of the 2010 American Control Conference, 2010
This paper presents the nonlinear design of excitation controller and power system stabilizer (PSS) aimed at ensuring transient stability and satisfactory post-fault voltage regulation following a large disturbance. The proposed design offers the possibility to select the PSS gains so as to achieve both swings damping in an assigned time interval and ...

CNN based power system transient stability margin and voltage stability index prediction

2013 IEEE Computational Intelligence Applications in Smart Grid (CIASG), 2013
Operators at electric grid control centers are faced with the task of making important decisions in real-time. With the plethora of data available it becomes important to extract information from the available data, based on which knowledge of system condition can be formed. This knowledge can then be used in decision making.

Use of Voltage Stability Assessment and Transient Stability Assessment Tools at PJM Interconnection

2021
Over the past few decades, PJM has moved voltage, transient, and dynamic stability analysis—historically the domain of planners and back-office engineers—into the control room. PJM utilizes the Real-Time Transfer Limit Calculator (RTTLC) to perform voltage stability analysis and determine operation limits.

Voltage sensitivity-based transient voltage stability analysis considering HVDC recovery characteristics

TENCON 2015 - 2015 IEEE Region 10 Conference, 2015
This paper presents a method based on V-Q sensitivity and modal analysis to study the transient voltage stability of receiving AC network with HVDC feeding. When faults of receiving network occur, HVDC recovery characteristics are analyzed, which have an important effect on voltage stability of receiving network.

A transient voltage stability index based on critical equivalent impedance

2014 International Conference on Power System Technology, 2014
Criteria and indices of transient voltage stability have attracted much attention recent years. It is a difficult problem since dynamics of load components are involved, such as induction motors and HVDC converters. A transient voltage stability index based on critical equivalent impedance and time-domain simulation is proposed in this paper.

Influence of synchronous condenser transient parameters on voltage stability of HVDC

2018 13th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2018
Large-capacity synchronous condenser can provide a powerful dynamic reactive power for the HVDC transmission system. The dynamic characteristic of reactive power is mainly related to the parameters of synchronous condenser. Therefore, it is very important to study the influence of transient parameters on the voltage stability of AC-DC system.
