This paper presents a mixed integer linear programming formulation for load-side control of electrical energy demand. The formulation utilizes demand prediction to determine if control actions are necessary, and it schedules both shedding and restoration times based on an optimization model that minimizes the net cost of load shedding. Operational constraints are satisfied through the use of mi...

We present a method to design distributed generation and demand control schemes for primary frequency regulation in power networks that guarantee asymptotic stability and ensure fairness of allocation. We impose a passivity condition on net power supply variables and provide explicit steady state conditions on a general class of generation and demand control dynamics that ensure convergence of ...

Frequency control rebalances supply and demand while maintaining the network state within operational margins. It is implemented using fast ramping reserves that are expensive and non-renewable, and which are expected to grow with the increasing penetration of renewables. The most promising solution to this problem is the use of demand response, i.e. load participation in frequency control. Yet...

The size of applications is becoming greater every day. Software components enable developers for easily building large applications with basic reusable parts. However, there is a need for a system support to allow these applications to scale to many users and to large networks. Current methods for load balancing cannot be applied, since they are mostly designed for local area networks and the ...

The potential of the Grid computing paradigm has led to the creation of several regional and national Grid environments. These environments are, however, like “Grid islands” with no resource sharing between them. We have presented an architecture to enable internetworking of Grids for resource sharing based on peering arrangements between Grids. This architecture and related mechanisms and poli...

The increase of energy consumption and the related costs in large data centers has stimulated new researches on techniques to optimize the power consumption of the servers. In this paper we focus on systems that should process a peak workload consisting of different classes of applications. The objective is to implement a policy of load control which allows an efficient use of the power deploye...

XML/GML/SVG based approaches are promising for building Web-based geographic information system (WebGIS). However, current XML/GML/SVG based WebGISs are lacking in spatial analysis. Some of them are designed for web mapping only. Others adopt a server-side solution for spatial analysis, which suffers from the “bottleneck” problem, and results in a high network transmission load. Load balancing ...
