In smart power grids, a smart meter placed at a consumerend point reports fine-grained usage information to utility providers. Based on this information, the providers can perform demand prediction and set on-demand pricing. However, this also threatens user privacy, since users’ specific activity or behavior patterns can be deduced from the finely granular meter readings. To resolve this issue...

ABSTRACT We present a dynami model of agent-based load balan ing on grids. Our goal is to explore the e e ts of agents' strategies on the quality of load balan ing. We show that under ertain onditions, the model exhibits a known phenomenon that the load is perfe tly balan ed. This result is in agreement with re ent experimental results on load balan ing through Anthill. On the other hand, under...

This paper presents the results of the analysis of 56,000 flat grids in a form suitable for minimum weight design.

We propose an integrated architecture for smart grids, that supports data aggregation and access control. Data can be aggregated by home area network, building area network and neighboring area network in such a way that the privacy of customers is protected. We use homomorphic encryption technique to achieve this. The consumer data that is collected is sent to the substations where it is monit...

Commercialization of Grid resources will become more and more important as utility computing and the deployment of Grids gains momentum. This results in the necessity to not only base Grid components on technical aspects, but also to include economical aspects in their design. This paper presents a framework that links technical and economical aspects to the management of computational resource...

An overview is given of finite volume central schemes for the numerical solution of systems of conservation and balance laws. Well balanced central schemes on staggered grid for the Saint-Venant model or river flow are considered. A scheme which is well balanced for channels with variable cross section is introduced. Finally, a scheme which preserves non static equilibria is introduced, and som...

Real-world flood simulators often use first-order finite volume (FV1) solvers of the shallow water equations with efficiency enhancements exploiting parallelisation on Graphical Processing Units (GPUs) and static adaptivity fixed grids. A second-order discontinuous Galerkin (DG2) solver greatly increases accuracy in predictions uniform grids, where it is comparatively costly to run, but its pra...

The paper presents a set of control system scenarios implemented in two testbeds developed in the context of the European Project CRUTIAL CRitical UTility InfrastructurAL Resilience. The selected scenarios refer to power control systems encompassing information and communication security of SCADA systems for grid teleoperation, impact of attacks on inter-operator communications in power emergen...

Grid computing has recently migrated from traditional high performance and distributed computing to pervasive and utility computing based on the advanced capabilities of the wireless networks and the lightweight, thin devices. This has as result the emergence of a new computing paradigm which is the Mobile Grid. This paper provides a discussion on Mobile Grid definition, the basic motivation an...

Utility distribution grids in the US are experiencing proliferation of Distributed Generation (DG) largely due to the need to comply with goals set by Renewable Portfolio Standards (RPS), the availability of economic incentives, and technology cost reductions. Interconnecting properly-sized DG units at strategic locations in the distribution grid may lead to important benefits and improve power...
