Microgrids have emerged as a practical solution to improve the power system resilience against unpredicted failures and outages. offer substantial benefits for customers through local supply of domestic demands well reducing curtailment during possible disruptions. Furthermore, interdependency natural gas networks is key factor in energy systems’ critical hours. This paper suggests probabilisti...

A video-on-demand server must satisfy a large customer base and a diverse archive of movies under changing movie popularity and daily load peaks. These requirements must be satisfied under the constraints imposed by storage device costs, capacities, I/O bandwidths, and geographic locations. In this paper we describe a partitioning of video data (movies) onto a video-on-demand storage hierarchy ...

A novel state-space model of a multi-node supply chain is presented, controlled via local proportional inventory-replenishment policies. The model is driven by a stochastic sequence representing customer demand. The model is analyzed under stationarity conditions and a simple recursive scheme is developed for updating its covariance matrix. This allows us to characterize the “bullwhip effect” (...

We propose new probabilistic models for the spatial distribution of supply and demand and use the models to determine how the trip length distribution is affected by the relative shortage or excess of supply, the spatial clustering of supply and demand, and the degree of attraction or repulsion between supply and demand at different spatial scales. The models have a multiplicative structure and...

Today's drivers of battery electric vehicles must deal with limited driving range in a sparse charging infrastructure. An accurate prediction energy demand and is therefore important enables reliable routing charge planning applications. Predictions entail uncertainty, which can be considered directly the use probabilistic algorithms. Machine learning algorithms are frequently applied this cont...

abstract: enviromental concerns, improvements in renewable energy technologies, governmental incentives for the use of these resources, and increased t&d; costs, are the main factors driving the energy sector into a new era, where considerable portions of electrical demand will be met through widespread installation of distributed energy resources (ders). the virtual power plant (vpp) is a dece...
