The Network Of Workstations (NOWs) is the trend for distributed computing, and the costeffectiveness of networking system is one of the key issues for NOWs. The IEEE 1394 bus can be a cost-effective solution for linking a network of computers, in this paper, we tested the performance of IEEE 1394 on the Linux system, and discussed how to improve the IEEE 1394 performance towards cluster computi...

Power system security enhancement is a major concern in the operation of power system. In this paper, the task of security enhancement is formulated as a multi-objective optimization problem with minimization of fuel cost and minimization of FACTS device investment cost as objectives. Generator active power, generator bus voltage magnitude and the reactance of Thyristor Controlled Series Capaci...

The problem of Transmission Loss Allocation (TLA) among the power system agents has become more important with the increase of the competition level in electricity markets. In this paper different Transmission Loss Allocation methodologies are considered. The comparison between them, which is not available in the literature, has been made. The methods considered in this paper are; Postage Stamp...

This paper describes an application of boundary scan IEEE Std. 1149.1 at system level. It provides the description of the design and the implementation options of a VME boundary scan controller board prototype and the corresponding software. The prototype was designed to use the Module Test and Maintenance (MTM) bus, existing in the VME 64x backplane, to apply the IEEE 1149.1 test vectors to a ...

This paper presents a new approach for estimating and improving voltage stability margin from phase and magnitude profiles of bus voltages using sensitivity analysis of Voltage Stability Assessment Neural Network (VSANN). Bus voltage profile contains useful information about system stability margin including the effect of loadgeneration pattern, line outage and reactive power compensation, so i...

The progression towards smart grids, integrating renewable energy resources, has increased the integration of distributed generators (DGs) into power distribution networks. However, several economic and technical challenges can result from the unsuitable incorporation of DGs in existing distribution networks. Therefore, optimal placement and sizing of DGs are of paramount importance to improve ...

In this paper, swarm optimization hybridized with differential evolution (PSO-DE) technique is proposed to solve static state estimation (SE) problem as a minimization problem. The proposed hybrid method is tested on IEEE 5-bus, 14-bus, 30-bus, 57-bus and 118-bus standard test systems along with 11-bus and 13-bus ill-conditioned test systems under different simulated conditions and the results ...

In the deregulated power systems, transmission congestion is one of the significant and main problems of the electrical networks which can cause incremental cost in the energy. This problem has resulted to new challenging issues in different parts of power systems which there was not in the traditional systems or at least had very little importance. Transmission congestion happens when the maxi...
