Grid Technology has proven to be a suitable means for the efficient sharing of various resources within a well–defined community. The EC–funded projects LeGE–WG and e–LeGI have set out to apply this technology for technology enhanced learning services. Previously, the applicability of distributed skill maps for adaptive e–Learning within a grid network has been discussed. In this paper, we prop...

There are numerous advantages of using Electric Vehicles (EVs) as an alternative method of transportation but an increase in EV usage in the existing residential distribution grid poses problems such as overloading the existing infrastructure. In this paper, we have modeled and simulated a residential distribution grid in GridLAB-D (an open-source software tool used to model, simulate, and anal...

The main goal of this study is the use of Lyapunov’s stability theory to a three-phase four-wire shunt active power filter (SAPF), since this method has been applied effectively to other areas of converter. The dynamic model of the SAPF is first established, after that, a combination of fuzzy tracking control and Lyapunov function is suggested in order to impose a desired transient waveform on ...

This paper presents a status report on some of the highlights that have taken place within the OGSADAI project since the last AHM. A description of Release 6.0 functionality and details of the forthcoming release, due in September 2005, is given. Future directions for this project are discussed. This paper also describes initial results of work being done to systematically benchmark recent OGSA...

The design of high integrity, area efficient power distribution grids has become of practical importance as the portion of on-chip interconnect resources dedicated to power distribution networks in high performance integrated circuits has greatly increased. The inductive characteristics of several types of gridded power distribution networks are described in this paper. The inductance extractio...

Closed-ring operation of distribution grids has several advantages over more common distribution grid configurations incorporating normally-open points. As power flows are able to naturally balance out between feeders of a ring shaped distribution grid, it is expected that peak loading will be reduced, and with that, grid losses. As such, investment costs can be postponed or avoided and operati...

Smart grid has been introduced to address power distribution system challenges. In conventional power distribution systems, when a power outage happens, the maintenance team tries to find the outage cause and mitigate it. After this, some information is documented in a dataset called the outage dataset. If the team can estimate the outage cause before searching for it, the restoration time will...

This paper describes the concept and characteristics of smart grid distribution systems, basic difference between conventional and smart grid distribution systems, functional management and reliability evaluation of smart grid distribution systems. In smart grid distribution system, remotely controlled high rated power electronic switches are used in the place of normal disconnecting switches o...

An adaptive unstructured grid generation scheme is introduced to use finite volume (FV) and finite element (FE) formulation to solve the heat equation with singular boundary conditions. Regular grids could not acheive accurate solution to this problem. The grid generation scheme uses an optimal time complexity frontal method for the automatic generation and delaunay triangulation of the grid po...
