With more penetration of solar power plants, photovoltaic generation will be exerting more influences on the power system. The main purpose of this paper is to study the dynamic characteristics of the power system with photovoltaic generation. First, power flow and bus voltage variations of the system with photovoltaic generation are calculated. Then according to the related interconnection cri...

Shear band spacing in Zr-based bulk metallic glasses (BMGs) under dynamic loads is found to vary with position and local strain rate in the indented region. To investigate the dependence of shear band evolution characteristics on local strain rate and normal stress, a micromechanical model based on momentum diffusion is proposed. The thermomechanical model takes into account the normal stress d...

In development of floating photovoltaic generation system, finding a suitable place of installation is as important as development of economically feasible and stable structure. Especially since floating photovoltaic system has its facility floating on water surface, it is extremely important to review the effects of weather conditions such as wind, water flow and floating matters, various fact...
