A New Line Voltage Stability Index (NLVSI) For Voltage Stability Assessment
2019Power system is probably one of the most complex dynamical systems. In these systems, active and reactive power demand is increasing day by day, other way it can be said that the stress on these systems is increasing. Under these stressed conditions, they are operating at the stability limits to meet their load demand.

Voltage Stability Analysis of Radial Distribution Networks
Electric Power Components and Systems, 2003 The paper presents voltage stability analysis of radial distribution networks. A new stability index is proposed to identify the nodes that are on the verge of voltage collapse. The value of the proposed voltage stability index is calculated at each node

Introduction to Voltage Stability
2021Voltage stability is a branch of power system stability that has developed late. In general, the research on voltage stability can be divided into three stages. In Stage I from 1940s when the first voltage stability criterion dQ/dU [1] was put forward by Malkovich, a Russian scholar, to the mid-1970s, insufficient attention was been paid to voltage ...

On Electronic Voltage Stabilizers
Review of Scientific Instruments, 1939Voltage stabilizing circuits employing thermionic tubes can be classified into four groups, according to their derivation from (1) the transconductance bridge, (2) the amplification factor bridge, (3) the simple degenerative amplifier, and (4) combination circuits involving two or more of the foregoing classes or utilizing amplified control voltages ...

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.

In this chapter, we extend the techniques of intrinsic geometry and examine the problem of voltage stability in network theory. In order to carry out this investigation, we determine stability domains by first specifying the three-parameter model for the reformulation of the problem.

Voltage stability of microgrids
2019This chapter focuses on voltage stability of microgrids. Some control schemes to maintain voltages of all the buses of a microgrid at acceptable levels in normal conditions and after being subjected to disturbances will be presented. Voltage stability enhancement and reactive power sharing in inverter-based microgrids are discussed, including droop ...

Stabilization of Load Voltages
2015In the present chapter, the results of Chap. 10 for interpretation of changes or “kinematics” of load regimes are used. Obtained geometrical transformations describe the movement of an operating point along regulation and stabilization trajectories.
