Based on the component approach, three kinds of dynamic load models, including a single –motor model, a two-motor model and composite load model have been developed for the stability studies of Khuzestan power system. The study results are presented in this paper. Voltage instability is a dynamic phenomenon and therefore requires dynamic representation of the power system components. Industrial...

This paper studies dynamic stability of functionally graded beams with piezoelectric layers subjected to periodic axial compressive load that is simply supported at both ends lies on a continuous elastic foundation. The Young’s modulus of beam is assumed to be graded continuously across the beam thickness. Applying the Hamilton’s principle, the governing dynamic equation is established. The eff...

We propose a completely general, informed randomized dynamic load balancing method called random seeking (RS) suitable for parallel algorithms with characteristics found in many search algorithms used in artificial intelligence and operations research and many divide-and-conquer algorithms. In it, source processors randomly seek out sink processors for load balancing by flinging “probe” message...

The application of reconfigurable computing technology to solve high performance computing problems has received increasing attention in recent years. N-body problems such as Molecular Dynamics simulations are common candidates for such studies. The ability to perform dynamic load-balancing offers the potential of improving performance, but the implementation of hardware architectures implement...

the effect of axial deformation of shell particles on the dynamic instability (flutter) of cantilevered cylindrical shells made of functionally graded materials (fgm) under an end axial follower force is addressed. to this end, at first, results for free vibration of fgm cylindrical shells were verified with previous outcomes and they were in very good agreement. then, the effect of axial defor...

This paper reports design and preliminary evaluation of an integrated load distribution-load balancing algorithm which was targeted to be both efficient and scalable for dynamically structured computations. The computation is represented as a dynamic hierarchical dependence graph. Each node of the graph may be a subgraph or a computation and the number of instances of each node is dynamically d...

Nowadays, the usage of load emulators, is the best method for implementation and analysis of different electrical load change scenarios in laboratories. This paper presents an improved programmable load emulator which can emulate both reference active and reactive power simultaneously. The proposed control system can track the dynamic load changes rapidly and accurately in addition to pulse cha...

Voltage unbalance negatively affects both distribution network operators (DNOs) and customers by introducing overheating, accelerated thermal ageing of equipments, reduced efficiency and therefore additional financial cost. Once a new source of unbalance appears in the network, the overall degree of unbalance of the network will be increased, contributing to the system losses additionally. The ...
