Power-Electronics-Enabled Transient Stabilization of Power Systems
2013Transient stability of electric energy grids is defined as the ability of the power system to remain in synchronism during large disturbances. If the grid is not equipped with controllers capable of transiently stabilizing system dynamics, large disturbances could cause protection to trigger disconnecting the equipment and leading further to cascading ...

Transient Stabilization of Multimachine Power Systems
2006In this chapter we provide a solution to the long-standing problem of transient stabilization of multimachine power systems with nonnegligible transfer conductances. More specifically, we consider the full 3n-dimensional model of the n-generator system with lossy transmission lines and loads and prove the existence of a nonlinear static state feedback ...

Transient Stabilization in Systems with Wind Power
2013This chapter analyzes transient stability problems in networks with high wind penetration. Disturbances caused by wind power perturbations and major equipment failures are considered, and their impact on system dynamics is analyzed. Next, the potential of power-electronically switched devices for the stabilization of system dynamics during high energy ...

Transient Stability of Dissipative Power Systems
IFAC Proceedings Volumes, 1984Abstract Stability criteria for on-line analysis of transient processes in power systems are discussed. A method to approximate separation manifolds by energy surfaces of corresponding conservative systems is derived by using the theory of differential manifolds in the spirit of Its applications in classical mechanics. Closed form stability criteria,

Improving of Transient Stability of Power Systems Using UPFC
IEEE Transactions on Power Delivery, 2005The objective of this paper is to answer to the following question: How the unified power flow controller (UPFC) parameters should be controlled in order to achieve the maximal desired effect in solving first swing stability problem. This problem appears for bulky power systems with long transmission lines.

Review on Transient Voltage Stability of Power System
2020 IEEE Sustainable Power and Energy Conference (iSPEC), 2020In recent years, there have been frequent blackouts caused by voltage instability worldwide, causing huge economic losses. The highly centralized load center at the receiving end needs to feed a lot of energy from the remote power center in China, which makes the transmission capacity of the power grid closer to the transmission limit, and the ...

A Unified Scheme for Power System Transient Stability Simulation and Transient Stability Assessment
2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019Transient stability assessment (TSA) is critical for power system stability analysis and control. Among all efforts to achieve TSA, the transient stability simulation(TSS) plays a fundamental role. In this paper, a unified scheme is proposed for TSS and TSA of numerous power system transient scenarios. The scheme mainly consists of two parts, which are
