State estimation in the energy management center of active distribution networks has attracted many attentions. Considering an increase in complexity and real-time management of active distribution networks and knowing the network information at each time instant are necessary. This article presents a two-step multi-area state estimation method in balanced active distribution networks. The prop...

content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....

The building sector is responsible for about 7% of overall greenhouse gas emissions in the US. Cutting by electrifying heating and cooling supply through heat pumps (HPs) leads to an increase electricity demand potential overloading lines transformers distribution systems. Although many studies investigate maximum HPs existing systems Europe, they neglect a relieving effect combining with rooft...

Merging the adaptive networks with the free space optical (FSO) communication technology is a very interesting field of research because by adding the benefits of this technology, the adaptive networks become more efficient, cheap and secure. This is due to the fact that FSO communication uses unregistered visible light bandwidth instead of the overused radio spectrum. However, in spite of all ...

Natural gas is now the largest source of energy in the international community and Iran has the largest natural gas reservoirs in the world. The development of gas networks has covered 98% of the urban population and more than 85% of the rural population of Iran. On the other hand, the exporting and conversion of natural gas into petrochemical products, electricity generation and use for indust...

We consider gas flow in pipeline networks governed by the isothermal Euler equations and introduce a new modeling of compressors in gas networks. Compressor units are modeled as pipe–to–pipe intersections with additional algebraic coupling conditions for the compressor behavior. We prove existence and uniqueness of solutions with respect to these conditions and use the results for numerical sim...

The use of ionic liquids (ILs) for gas separation processes recently has attracted much attention due to high solubilities of different gaseous species in ionic liquids [1]. The preparation of supported ionic liquid membranes (SILMs) is also reported for selective separation of different organic or gaseous compounds. Research activities have amongst others focused on CO2 separation from gas str...

Natural gas usually contains significant amounts of acid gases when it is extracted from underground reservoirs. Therefore, it must be treated by appropriate processes to remove these acidic components. In this study, the simultaneous absorption of carbon dioxide and hydrogen sulfide from natural gas into diethanol amine solution was simulated using CFD. Absorption process was performed in a we...

In this paper we consider the problem of creating a two dimensional spatial representation of gas distribution with a mobile robot. In contrast to previous approaches to the problem of gas distribution mapping (GDM) we do not assume that the robot has perfect knowledge about its position. Instead we develop a probabilistic framework for simultaneous localisation and occupancy and gas distributi...

In this paper, the combined natural gas and electric optimal power flow (GEOPF) is presented. It shows fundamental modeling of the natural gas network to be used for the GEOPF, and describes the equality constraints which describe the energy transformation between gas and electric networks at combined nodes (i.e., generators). We also present the formulation of the natural gas loadflow problem,...
