Dispatch optimization incorporating transient and voltage stability constraints
2000 Power Engineering Society Summer Meeting (Cat. No.00CH37134), 2002Stability aspects have often been incorporated in the dispatch/pricing procedure using trial and error methods, or approximated in the dispatch optimization directly as a set of linear constraints on generation/transmission. This paper presents the preliminary experiences with the development of an OPF model that incorporates both transient and voltage

Electric Power Components and Systems, 2006
This article presents a method to discriminate between transient voltage stability and voltage sag. Transient modeling based on matching pursuit with an overcomplete dictionary of wavelet functions is a powerful tool in the analysis of the transient phenomena in power systems because of its ability to accurately represent them in both time and ...

Optimal Quasi-Synchronous Compensator Dispatch for Transient Voltage Stability
2018 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2018The quasi-synchronous compensator is a type of synchronous generator, which can work in a low loading factor and provide reactive power support to power system. For the enhancement of transient voltage stability, this paper proposes an optimal dispatch method by regulating those quasi-synchronous compensators.

Transient stability enhancement and voltage regulation of power systems
IEEE Transactions on Power Systems, 1993Improvement of the transient stability and voltage regulation of a single-machine-infinite-bus power system under the effects of a symmetrical three-phase short-circuit fault is detailed. The dynamical model of the system is described. A design strategy for nonlinear controllers is considered, and the design of a nonlinear variable-structure excitation

Multi-objective congestion management incorporating voltage and transient stabilities
Energy, 2009Congestion in a power system is turned up due to operating limits. To relieve congestion in a deregulated power market, the system operator pays to market participants considering their bids to alter their active powers. After relieving congestion, the network may be operated with a reduced voltage or transient stability margin because of hitting ...

Analysis of Transient Voltage Stability via Quadratic Approximation Method
2006 International Conference on Power System Technology, 2006Based on the quadratic approximation of the stability region boundary, this paper proposes a transient voltage stability margin index, and analyzes the transient voltage stability of a one-generator-one-load system including an induction motor with electro-mechanical transient model.

Transient Stability Improvement Using Thyristor Controlled Quadrature Voltage Injection
IEEE Transactions on Power Apparatus and Systems, 1981A thyristor controlled quadrature voltage injection transformer is used to improve the transient stability performance of a generator connected, through a transmission circuit, to a power-system. The paper discusses the effect of alternative control strategies and shows that not only can first swing maximum angle be reduced, but the subsequent ...

Transient Stability of Grid-forming Voltage-source Converters-Slides
2023Abstract: Grid-forming voltage-source converters (GFM-VSCs) are emerging as an attraction solution for developing the future 100 percent power electronic based power systems. However, different from synchronous generators whose synchronization is governed by the physical law of swing equation, the synchronization dynamics of GFM-VSC is determined by ...

CNN based power system transient stability margin and voltage stability index prediction
2013 IEEE Computational Intelligence Applications in Smart Grid (CIASG), 2013Operators 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
2021Over 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.
