Load balancing is an important issue in distributed systems. In addition, using distributed generation sources such as photovoltaic is increasing. Power electronic converters are main interfaces between the sources and the grid. In this paper, a method has been proposed to reduce the load imbalancing in distribution networks using PV Grid Interface Converter. Two DC/DC and DC/AC converters have...

During the past several years, the grid application executed same jobs on one or more hosts in parallel, but the recent grid application is requested to execute different jobs linearly. That is, the grid application takes the form of workflow application. In general, efficient scheduling of workflow applications is based on heuristic scheduling method. The heuristic considering relation between...

Users and resources frequently join and leave computational grid, hence the state of the grid changes dynamically. So, an effective job scheduling strategy is needed that consider the dynamically changed conditions in the grid. Most of the existing scheduling strategies are mainly based on selecting resources that have less resource response time or less grid bandwidth while these resources may...

The parallel and distributed systems represent one of the important solutions proposed to ameliorate the performance of the sequential association rule mining algorithms. However, parallelization and distribution process is not trivial and still facing many problems of synchronization, communication, and workload balancing. Our study is limited to the workload balancing problem. In this paper, ...

In this paper, a novel and simple control strategy, based on state feedback method is suggested to control the power injection system (PIS). The considered PIS is composed of, a DC voltage source, a voltage source inverter (VSI) and a L-C-L filter. The DC source includes the battery source with boosted voltage. The battery can be charged with photovoltaic cells. Since, the grid voltage acts as ...

Developing Data Grids has increasingly become a major concern to make Grids attractive for a wide range of data-intensive applications. Storage subsystems are most likely to be a performance bottleneck in Data Grids and, therefore, the focus of this paper is to design and evaluate a data-aware load-balancing strategy to improve the global usage of storage resources in Data Grids. We build a mod...

Grid technology, which together a number of personal computer clusters with high speed networks, can reach the same computing power as a supercomputer does, also with a minimum cost. However, heterogeneous system is called as grid. Scheduling independent tasks on grid is more difficult. In order to utilize the power of grid completely, we demand an efficient job scheduling algorithm to execute ...

Parallel connection of inverter modules is a solution to increase reliability, efficiency and redundancy of inverters in Micro-Grid system. Proper load sharing among parallel inverters is a key point. The circulating current among the inverters can greatly reduce the efficiency or even cause instability of the system. In this paper, a control strategy for improving the load sharing performance ...

Brushless doubly fed reluctance generator (BDFRG) has been recently suggested as a wind generator. Different control methods are presented in literature for the BDFRG, but there is a gap on control under unbalanced grid voltage condition (UGVC). This paper presents a predictive direct power control (PDPC) method for the BDFRG under UGVC. The proposed PDPC method is based on power compensation s...
