Experiments have provided suggestive but inconclusive insights into the relative contributions of transmembrane voltage and intracellular calcium handling to the development of cardiac electrical instabilities such as repolarization alternans. In this study, we applied a novel combination of techniques (action potential voltage clamping, calcium-transient clamping, and stability analysis) to ca...

This paper proposes an algorithm for optimal placement of FACTS devices in transmission line to maintain the power system voltage stability and optimal sizing of the FACTS device. The aim of this paper is to improve voltage stability and reduce the total power losses. Here, voltage stability means no variation in the voltages of each bus beyond its boundaries and system stability is the ability...

It can’t be ignored that the impact of distribution network to the static voltage stability of the distributed generation. In this paper, we first introduce the stability indices of the traditional grid on static voltage and the analytical method, at the same time, we put forward the corresponding advantages, disadvantages and applicable scope. Then, we present a summary of the current research...

Abstract—In today’s world, electrical energy has become an indispensable component of all aspects of modern human life. Reliability, security and stability are the key aspects of any power system. Failure to meet any of these three aspects results into a great impediment to modern life. Modern power systems are being subjected to heavily stressed conditions leading to voltage stability problems...

The stability index is a function of real & reactive power injected at that node as well as of node voltage. The report presents stability analysis of radial distribution networks. Two voltage stability indexes are used for identifying the node, which is most sensitive to voltage collapse. Therefore to calculate node voltages for varying operating conditions a simple load flow technique for sol...

This paper focuses on the grid-connected photovoltaic (PV) systems and their impact on the voltage stability of the power system. The modeling of the PV systems for the voltage stability analysis is presented. The impact of a large penetration of PV generation on the voltage stability is examined through numerical simulations conducted on the IEEJ West 10-machine test system. Several of interes...

in this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is presented. the majority of existing control approaches are based on control torque strategy, which require the knowledge of robot dynamics as well as dynamic of patients. this requires the controller to overcome complex problems such as uncertainties and nonlinearit...
