Voltage stability index for online voltage stability assessment
2015 North American Power Symposium (NAPS), 2015This paper proposes a voltage stability index to predict voltage collapse in power system. The index is based on maximum loading capability of the bus combined with a thevenin equivalent method for the aggregated representation. The technique is applied to transmission test system. Using thevenin equivalent calculated by fast load flow or PMU data, the

The proximity of power systems to voltage collapse can be calculated for any of the buses using to the theory of bifurcation and multiple solutions to power flow behavior, in terms of system indicators such as real and reactive power. These indicators can be measured to identify voltage collapse.

TENCON '91. Region 10 International Conference on EC3-Energy, Computer, Communication and Control Systems, 2005
Radial voltage stability poses problems for power system planners and operators. This paper presents methods and aids which can meet the quite distinct needs of both planners and operators, with an emphasis on the practical aspects of the problem. An actual disturbance is described in which the first phase was due to system voltage instability, and ...

IET Conference on Renewable Power Generation (RPG 2011), 2011
The use of renewable energy sources is escalating every year. Thus, there is an increase of smaller generating units connected directly to distribution networks close to demand consumption, designing micro-grids. These sources must provide the power quality required to ensure the stability and reliability of the power system.

Static Voltage Stability Analysis of Distribution Systems Based on Network-Load Admittance Ratio
IEEE Transactions on Power Systems, 2019It is well known that a single (constant power) load infinite-bus system reaches a static voltage stability limit point, or equivalently, a singularity point of the power flow Jacobian, at the unity line-load admittance ratio, i.e., the equivalent ...

Stability of Voltage Regulators
Transactions of the American Institute of Electrical Engineers, 1950THE PRESENCE in many voltage regulator circuits of nonlinear control elements has prevented a complete mathematical treatment of the subject. However, Liapounoff's theory1 ofthe stability of dynamic systems affords a solution to the problem of stability of electric circuits subjected to small displacements from equilibrium.
