Power System Transient Stability Based on SVM
Advanced Materials Research, 2012In order to overcome the lack of which power system transient stability assessment model can not continue to learn and update the model online, in this chapter, a incremental learning method of support vector machine is proposed . The new data is added to the solution by constructing a recursive solution , which provides a new way of learning online ...

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 stability analysis of TNGT power system
2014 IEEE 8th International Conference on Intelligent Systems and Control (ISCO), 2014The increase in size and complexity of power system networks with a large number of interconnections has exposed the system to various contingencies, which lead to system instability. Therefore, it is necessary for a power system to remain in a state of operating equilibrium under normal operating conditions and to regain an acceptable state of ...

Robust Control for Power System Transient Stability
1993 American Control Conference, 1993The complexity of power system transients as well as a wide range of operating regimes are beyond practical limitations of modeling techniques used in control design. Thus, in order to provide reliable system operation, a controller must be insensitive to modelling errors.

Agent based power system transient stability enhancement
2012 IEEE International Conference on Power System Technology (POWERCON), 2012This paper describes an intelligent agent approach to power system fault diagnosis during disturbance condition for the enhancement of the transient stability with better coordination of protection devices using auto-reclosing technique. The protection device agents can dynamically adapt the change in the system and thus they have the full flexibility ...

Transient Stability Regions of Multimachine Power Systems
IEEE Transactions on Power Apparatus and Systems, 1966Analysis of the stability of power systems following a transient disturbance involves the study of a large set of nonlinear differential equations. A new approach to the quantitative study of the transient stability of large power systems is presented, using the second method of Liapunov.

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 Boundary Visualization for Power System
2006 International Conference on Power System Technology, 2006In terms of monitored operational information, a visual transient stability assessment (TSA) approach is presented to power system. In the procedure, the initial high-dimensional operation data points are projected into an intuitively understandable graphical representation with two-dimensional visualization. Moreover, the data with different operation

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 ...

Global Transient Stability and Voltage Regulation for Power Systems
IEEE Power Engineering Review, 2001Summary form only given as follows. This paper is concerned with the global control of power systems. It arises from the practical concern that transient stability and voltage regulation are both important properties of power system control, but they are ascribed to different model descriptions and relate to different stages of system operation (i.e ...
