The journey towards sustainable transportation has significantly increased the grid penetration of electric vehicles (EV) around world. connection EVs to power poses a series new challenges for network operators, such as loading, voltage profile perturbation, unbalance, and other quality issues. This paper presents coalescence knowledge on impact that electro-mobility can impose grid, identifie...

    Hub covering location problem, Network design,   Single machine scheduling, Genetic algorithm,   Shuffled frog leaping algorithm   Hub location problems (HLP) are synthetic optimization problems that appears in telecommunication and transportation networks where nodes send and receive commodities (i.e., data transmissions, passengers transportation, express packages, postal deliveries, etc....

in this article we present an algorithm for converting a network problem with several sources and several sinks including several transfer nodes and condition of supplying the demand of any sink from a particular source to the transportation problem.  towards this end, and considering the very special structure of transportation algorithm, after implementing the shortest path algorithm or solvi...

– We introduce a model for the dynamic self-organization of the electric grid. The model is characterized by a conserved magnitude, energy, that can travel following the links of the network to satisfy nodes’ load. The load fluctuates in time causing local overloads that drive the dynamic evolution of the network topology. Our model displays a transition from a fully connected network to a conf...

this paper proposes a new mathematical model for designing and planning postal parcels carriage and postal networks. the objective of postal network designing is to determine the location, size and connection between the postal stations in a city, province or country. in this paper, a kind of multiple locations-allocations hub problem with limited capacity in collecting, distributing and broadc...

Advanced metering infrastructure (AMI) is the core component in smart grid. Moreover, two-way communication between the user and the power utility is realized through AMI. Composition of AMI is described. AMI security requirements are illustrated. The threats on the smart meters, communications network, and data collector are analyzed, respectively. Passive and active defenses are investigated....

A networked dynamical system consists of numerous loosely coupled systems. These networked systems are found throughout our national infrastructure in the guise of our electrical power grid and transportation networks. Interruptions in the smooth operation of these networks can disrupt the lives of millions of users. Increased demand due to demographic shifts and greater regulatory burdens have...
