A new voltage stability control model was presented to guarantee the static voltage stability of power system using the active power constraints of weak branches as the static voltage stability margin constraints. A local index for voltage stability was used to recognize the key contingencies, the weak branches and their maximum active power. Based on DC power flow equations, a static security ...

Introduction: Muscular fatigue is a common phenomenon in daily sports activities and is worsening motor performance. The aim of this study was to determine the effect of neck muscular fatigue on static and dynamic postural control in elite male volleyball players. Correspondence: Maryam Mazidi, MSc. Department of Sp...

Stability augmentation systems make the aircraft more stable. There are SASs for both the dynamic stability (whether the eigenmotions don’t diverge) and the static stability (whether the equilibrium position itself is stable). First, we’ll look at the dynamic stability: how can we effect the eigenmotion properties? Second, we’ll examine the static stability: how do we make sure an aircraft stay...

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...
