The paper presents a detailed modeling and simulation of different control schemes of the real and reactive power flows in a three-phase voltage source inverter (VSI) interfacing a photovoltaic (PV) generation system to the power grid. Synchronisation of the inverter and grid AC waveforms is achieved using a phase-locked-loop (PLL) circuit. An effective decoupling strategy based on proportional...

The potential for Grid technologies in applied bioinformatics is largely unexplored. We have developed a model for solving computationally demanding bioinformatics tasks in distributed Grid environments, designed to ease the usability for scientists unfamiliar with Grid computing. With a script-based implementation that uses a strategy of temporary installations of databases and existing execut...

Monte Carlo applications are widely perceived as computationally intensive but naturally parallel. Therefore, they can be effectively executed on the grid using the dynamic bag-of-work model. This paper concentrates on analyzing the characteristics of large-scale Monte Carlo computation for grid computing. Based on these analyses, we improve the efficiency of the subtask-scheduling scheme by im...

In this paper, GridIMF provides the users with consistency while adapting to variability grid information. GridIMF designs hierarchical 3-tier information management model in accordance with participating intention, roles and operating strategies of grid information. In order to manage grid information in effective ways, GridIMF provides grid service while dividing to GVMS and GRMS. GVMS sugges...

Nowadays, the power system utility has started to consider the green power technology in order for the world to have a healthier environment. A small-scale hybridized solar PV-AC grid (HSPVACG) power system is proposed to be developed to operate with AC grid. This system consists of a photovoltaic array installed on the rooftop. Moreover the roof is flat, which implies that system can be placed...

BPEL4WS is a well-established business process standard that can be used to orchestrate service-based workflows. However, the rapid growth and automation demands of e-business and grid applications require BPEL4WS to provide enhanced semantic annotations to achieve the goal of business processes automation. Here, OWL-S (OWL for Web Services) is designed to represent such kind of semantic inform...

Against the problem of group task allocation with time constraints in open and dynamic grid environments, this paper proposes a decentralised indicator-based combinatorial auction strategy for group task allocation. In the proposed strategy, both resource providers and consumers are modeled as intelligent agents. All the agents are limited to communicating with their neighbour agents, therefore...

reaching an electricity system which is both economically efficient and environmentally friendly is motivating countries to design and execute different types of tou demand response programs. but there are certain deficiencies which prevent these programs to effectively modify the load shape. smart grid as a means could help the electricity system to reach the highest demand side management ...
