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...

The Karnaugh map popularly known as the K-map is a method to simplify a given Boolean expression. The Karnaugh Map (K-Map) based technique breaks down beyond six variable. Telecommunication engineer at Bells lab Maurice Karnaugh refined the works of Edward Veitch ad created these k maps. The results are transferred from truth table to the rectangular grid numbering of cells is done according to...

Under the present European directive concerning common rules for the internal market in electricity, distribution companies are not allowed to own Distributed Generation (DG) but encouraged to include it as a planning option to defer investment in traditional grid reinforcements. Distribution system operators (DSOs) have used the provision of capacity contracted to DG as a viable alternative un...

Terrain aided aircraft navigation can be used to detect and correct errors in inertial navigation systems The idea of terrain aided naviga tion is to measure the vertical distance to the ground and compare it with a map on board the aircraft The comparison between the mea surements and the map can be made in a number of ways Both batch and recursive algorithms have been applied to this problem ...

This paper presents a method for building a probability grid map for autonomous mobile robots with ultrasonic sensors using a data association filter (DAF). The method is based on evaluating the possibility that the acquired sonar data are all reflected by the same object. The DAF is able to associate data points with each other. Data affected by specular reflection are not likely to be associa...

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...
